What Are the Functions of the Cable Identifier
What Are the Functions of the Cable Identifier
1. Left and right direction indication: the left and right arrows show the cable position, which is convenient and intuitive. 2. Tracking error prompt: the innovative patented technology of AC signal direction measurement is used to eliminate the ground wire return and induced current interference of adjacent and cross pipelines. When correctly tracking the cable to be tested, the pointer points to the front; When tracking to the adjacent cable, the pointer will be backward and a question mark will be displayed to prompt the tracking error. 3. High anti-interference: the unique digital processing method can completely suppress the power frequency and harmonic interference of adjacent operating cables. 4. Sound prompt: when it is very close to the top of the cable, there is a sound prompt. 5. Single key measurement of pipeline depth and current intensity: it can directly read the depth value and the current carried by the cable. 6. Multiple detection methods: in addition to the traditional sound peak method and sound Valley method, innovative and accurate methods are especially provided. The sensing range of the traditional sound peak method is too large, which is not conducive to accurate detection. Although the sound Valley method is accurate, it can not distinguish the parallel cable. The accurate method has a very narrow response range, is very accurate, and can distinguish the parallel cable. It is a better way to find the path in the complex area of the pipeline. 7. Two active detection frequencies: 1kHz, suitable for basic off-line detection; 15KHz is suitable for special situations. 8. Passive detection: it can directly detect the running cable without connecting the signal generator, and can also be used to detect other pipelines. 9. Historical curve display: the screen displays the historical curve of signal amplitude to visually judge the signal change. 10. Uniqueness identification: the detection caliper is used to identify the uniqueness of the cable. Through the combined signal sent by the detection generator, the amplitude and direction of the current on the cable can be accurately measured, and the identification results can be clearly given. 11. Built in battery for easy replacement: built in Ni MH battery provides reliable charging mode. Rechargeable batteries and dry batteries can be used interchangeably and can be replaced easily. Even if the battery fails, it can be easily replaced without repair, and it is conducive to emergency use without timely charging. 12. Low power consumption and long battery life: the instrument can work continuously for more than 30 hours by using a fully charged Ni MH battery or a new alkaline battery. 13. Automatic shutdown function: when the instrument does not operate within 30 minutes, it will automatically shut down to reduce battery consumption; When the battery is under voltage, the instrument will also shut down automatically to protect the battery. 14. The casing is durable, light and easy to carry.

Cable Fault Detector_ Medical Devices Will Maintain High Growth in the Coming Years
The medical and pharmaceutical chamber of Commerce of the all China Federation of industry and Commerce established the medical device Professional Committee yesterday and issued the 2012 analysis statement of the medical device industry. The statement shows that the dependence of some domestic high-end medical equipment markets on imports has decreased slowly last year. According to the deployment of deepening medical reform and the spirit of the 2012 national health work conference, the statement implies that China's medical device industry achieved a total sales revenue of 68.7 billion yuan in the first half of 2012, a year-on-year increase of 20.27%, The overall requirements of this year's work are: closely focus on the central task of deepening medical reform. It is predicted that China's medical devices will maintain rapid growth in the next 5-10 years, and the industry as a whole will maintain a growth rate of more than 20%. Among them, the focus is on food safety, occupational disease prevention and drinking water safety. According to the statistics of the statement, at present, although the number of medical device enterprises across the country has reached more than 14000, the competition pattern of the medical device industry is relatively scattered. In 2012, the food safety and health supervision of the health system should pay close attention to the following aspects: first, do a good job in food safety, More than 80% of them are small and medium-sized enterprises. The scale of enterprises is small, and there are problems such as insufficient R & D investment and weak technical ability. Because of fierce competition and low profitability, enterprises can only produce medium and low-end products or provide spare parts for foreign enterprises. " The head of the association hinted.

Can People Fool Benevolent Brother's 'Alibi Trackers' and Escape?The Museum of Brother Benevolent has been broken into, and his Kindergarten Lunch Box has been vandalized. Both the Box and its glass case was destroyed by a small bomb. This happened at night.It is not clear how the vandal(s) got into the building, but it is huge and has many possible entrance points. There were no Alibi transmissions nearby at the time. Investigators are puzzled.What actually happened was that the sacred Lunch Box had been sent on a tour a few months earlier. Somebody took the opportunity to place the bomb in the Box then, and it was counting down until the fateful night.This was inspired by the novelCan bug trackers be used for tracking tasks other than programming?Bug trackers can definitely be used to track tasks other than programming bugs. As an example, our organization has successfully configured JIRA to handle our customer service department. JIRA is hugely configurable, and the manager at the time spent several weeks creating components, and custom fields to handle everything from new client signups, client setups, billing issues, client complaints and work requests, all the way to cancellations. We've been doing this now for several years, and the sales, client services, and the account management and accounts receivable departments are extremely comfortable with the process.A task is created for the client, and subtasks are created for each of the above issues that come up, whether it be the actual setup, work request, etc.Of course, whether or not something like this will work for you depends on your exact needs. With the examples you gave, I know JIRA would work for you. However, in your case, if you are just needing something like this for you and you only, there are many free or cheap lightweight online task management systems out there that would most likely work better.

Combined with the fact that bittorrent clients constantly inform the tracker about how much data they have downloaded and uploaded, this allows the tracker to record a users stats between sessions and even dynamic IP changes
Brief Introduction of Cable Identification Instrument
Brief Introduction of Cable Identification Instrument
The working principle of the cable identification instrument needs to add a special signal to the identified cable, which should be received by a special receiver. Using this characteristic, the cable to be found can be identified. The cable identification instrument works according to the following principles: the cable identification instrument consists of a signal generator, a receiving clamp signal detector and an indicator. The signal generator mainly generates special pulse modulation signals, which are added to the stopped tested cable through the output line. The receiving clamp is used to find the tested cable on site. When the receiving clamp detector detects the special signal applied to the cable, The electric meter pointer on the signal detector swings synchronously with the frequency of the applied signal, while the signals detected on other cable lines are much smaller and in the opposite direction. It is easy to determine the tested cable by indicating the amplitude and direction of the electric meter. When the receiving clamp signal detector is used in combination with the signal generator, it can be used to distinguish the charged state of the cable, or assist in finding the short circuit position of the cable. When receiving clamp signal detector is used, clamp the cable with clamp.

Principle of Cable Fault Tester
Principle of Cable Fault Tester
At present, the cable fault tester based on impulse flashover method used by the majority of users of power cable fault tester can easily roughly measure the distance of fault point with rangefinder when solving low resistance fault and dead ground fault of low-voltage cable (the distance test of such fault point does not need high-voltage discharge equipment, but uses low-voltage pulse method), However, the method of lighting fire, discharging and listening to sound is still used to locate the fault point. At the same time, the Pathfinder and fixed-point instrument of this kind of instrument are separated, which makes it impossible to synchronize the fixed-point when finding the path, and the fixed-point often deviates from the path. Moreover, due to the limitations of the principle, it is difficult to find the accurate path of the cable when finding the cable path, It is generally between 1-2 meters wide. Starting from practicability, hn-a10 series cable fault locator just makes up for the above defects. It can test the fault point location, buried depth and path synchronization of cable. The indication of fault, path and buried depth of the instrument is very intuitive, without technical analysis and completely independent of the operator's experience. It makes the originally tedious fault test work become a relaxed and interesting thing. Therefore, if the majority of impulse lightning cable tester users have another ht-tc cable fault locator and the original distance finder, they can form a set of perfect low-voltage cable fault tester. At the same time, the low resistance and open circuit faults of high-voltage cables can also be quickly fixed, and the work efficiency can be improved several times. In fact, the majority of power consuming enterprises and units rarely contact the maintenance of high-voltage cables in daily production, because the maintenance right of high-voltage cables is generally specially maintained by the prefecture and municipal power departments. The number of low-voltage cables is far greater than that of high-voltage cables. For enterprises, factories and mining units, residential areas, scientific research institutes, more developed towns and villages, colleges and universities, some small and medium-sized cities and county-level power supply bureaus, the solution of low-voltage cable faults is what they are most concerned about. In fact, what low-voltage cable users need is a tool tester with simple operation, convenient carrying, strong practicability, low price and suitable for field operation. Because the insulation strength of low-voltage cable is low, if the method of ignition and discharge is used to test the fault of low-voltage cable, we find that this method sometimes causes secondary fault. More seriously, after ignition and discharge, the service life of the cable will be reduced and the fault incidence will be increased, which will seriously affect the normal power supply and production.

The Optical Fiber Connector
The Optical Fiber Connector
A fiber optic connector is a detachable (active) connection between an optical fiber and an optical fiber. The two end faces of the optical fiber are precisely butted together so that the optical energy output from the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent. It also minimizes the impact on the system due to its involvement in the optical link, which is a basic requirement for fiber optic connectors. To some extent, fiber optic connectors affect the reliability and performance of optical transmission systems.Basic introductionA connecting device for re-plugging between optical fibers, also called a fiber optic movable joint. The main performance parameters (and typical values) are: insertion loss ( 5dB), plug-and-repeat repeatability and interchangeability between connectors (500 changes). When used in a large-capacity high-speed transmission system, reflection is also required to be small.IntroductionOptical fiber connectors can be divided into single-mode and multi-mode connectors of common silicon-based fibers according to different transmission media, and other fiber-optic connectors such as plastics; the structure of the connector can be divided into: FC , SC, ST, LC, D4, DIN, MU, MT, etc. Among them, ST connectors are usually used for wiring equipment terminals, such as fiber distribution frames, fiber modules, etc.; and SC and MT connectors are usually used for network equipment terminals. According to the shape of the end face of the fiber, there are FC, PC (including SPC or UPC) and APC; according to the number of cores of the fiber, there are also single core and multi-core (such as MT-RJ). Fiber optic connectors are used in a wide variety of applications. In the actual application process, we generally distinguish according to the structure of the fiber optic connector. Here are some common fiber connectors:FC type fiber optic connector This connector was first developed by NTT Japan. FC is an abbreviation of Ferrule Connector, which indicates that the external reinforcement method is a metal sleeve and the fastening method is a turnbuckle. At the earliest, FC type connectors, the mating end faces of the ceramic pins used were planar contact (FC). The connector has the advantages of simple structure, convenient operation and easy manufacture, but the fiber end face is sensitive to fine dust, and Fresnel reflection is easy to occur, and it is difficult to improve the return loss performance. Later, this type of connector was improved by using a pin (PC) with a spherical end face, and the external structure was not changed, so that the insertion loss and return loss performance were greatly improved.SC type fiber optic connector This is a fiber optic connector developed by NTT Corporation of Japan. The outer casing has a rectangular shape, and the structure of the pin and the coupling sleeve is exactly the same as that of the FC type. The end face of the pin is mostly made of PC or APC type; the fastening method is a plug-and-pin type, which is not required. Rotate. Such connectors are inexpensive, easy to insert and remove, have small fluctuations in insertion loss, high compressive strength, and high installation density.The ST and SC interfaces are two types of fiber connectors. For 10Base-F connections, the connectors are usually ST type. For 100Base-FX, the connectors are mostly SC type. The core of the ST connector is exposed and the core of the SC connector is inside the connector. Biconic Connector The most representative of these types of fiber optic connectors was developed by Bell Laboratories of the United States. It consists of two precision-molded ends with frusto-conical cylindrical plugs and a double-conical plastic sleeve inside. The coupling assembly of the barrel.DIN47256 fiber optic connector This is a connector developed by Germany. The connector and coupling sleeve of this type of connector have the same structural dimensions as the FC type, and the end face treatment adopts PC grinding. Compared with the FC type connector, the structure is more complicated, and the internal metal structure has a spring that controls the pressure, so as to avoid damage to the end surface due to excessive insertion pressure. In addition, the mechanical accuracy of such a connector is high, and the value of the insertion loss is small. MT-RJ type connector MT-RJ started with the MT connector developed by NTT, with the same latching mechanism as the RJ-45 LAN electrical connector. The optical fiber is aligned with the guide pin mounted on both sides of the small sleeve for easy transmission and reception. The machine is connected, and the connector end face fiber is a double-core (interval 0. 75mm) arrangement design, which is the next-generation high-density optical connector mainly used for data transmission.LC connector The LC connector was developed by the famous Bell Institute and is manufactured using a convenient modular jack (RJ) latch mechanism. The size of the pins and sleeves used is half that of ordinary SC, FC, etc. , which is 1. 25 mm. This can increase the density of the fiber optic connectors in the optical distribution frame. At present, in the single-mode SFF, the LC type connector has actually occupied a dominant position, and the application in multi-mode has also grown rapidly.MU type connector The MU (Miniature Unit Coupling) connector is the worlds smallest single-core fiber optic connector developed by NTT based on the most widely used SC-type connector. The connector uses a 1. 25mm diameter bushing and self-retaining. The advantage of the organization is that it enables high-density installation. With MUs l.25mm diameter bushings, NTT has developed a series of MU connectors. They have socket type optical connectors (MU-A series) for fiber optic cable connection, backplane connectors with self-holding mechanism (MU-B series), and simplified sockets for connecting LD/PD modules and plugs (MU-SR series) )Wait. With the rapid development of fiber-optic networks to larger bandwidths and larger capacity and the widespread use of DWDM technology, the demand for MU-type connectors will also grow rapidly.MC connectorIn 2012, the domestic communication company independently developed a smaller and denser MC connector than the LC connector. The Nippon MC Fiber Optic Active Connector is a high-density single-core fiber optic connector for high-density applications such as high-capacity central rooms and high-density data centers. The MC fiber optic connector has a high density and can double the LC connector in the same space, making it the worlds smallest and densest connector.The main parameters:General structureThe main purpose of fiber optic connectors is to achieve fiber optic connections. Optical fiber connectors that have been widely used in optical fiber communication systems are numerous in variety and structure. However, the basic structure of various types of fiber optic connectors is consistent, that is, most fiber optic connectors are generally made of high-precision components (composed of two pins and one coupling tube). Alignment of the fiber.In this method, the fiber is inserted into and fixed in the pin, and the surface of the pin is polished to achieve alignment in the coupling tube. The outer components of the pins are made of metal or non-metal materials. The butt end of the pin must be ground and the other end typically uses a bend limiting member to support the fiber or fiber optic cable to relieve stress. The coupling tube is generally made of two semi-synthetic, fastened cylindrical members made of ceramic, or bronze, and is equipped with a metal or plastic flange to facilitate the mounting and fixing of the connector. In order to align the fiber as precisely as possible, the processing precision of the pin and the coupling tube is very high. PerformanceThe performance of fiber optic connectors, first of all, optical performance, in addition to the interchangeability, repeatability, tensile strength, temperature and number of insertions and removals of fiber optic connectors.(1) Optical performance: For the optical performance requirements of the optical fiber connector, the two most basic parameters of insertion loss and return loss are mainly used.Insertion loss (InsertionLoss) is the loss of the effective optical power of the link caused by the introduction of the connector. The smaller the insertion loss, the better. Generally, the requirement should be no more than 0.5dB.ReturnLoss (ReflectionLoss) refers to the ability of the connector to suppress the reflection of the link optical power, and its typical value should be no less than 25dB. In the practical application of the connector, the surface of the pin has been specially polished to make the return loss larger, generally not less than 45dB.(2) Interchangeability and repeatabilityThe fiber optic connector is a universal passive device. For the same type of fiber optic connector, it can be used in any combination and can be used repeatedly. Therefore, the additional loss introduced is generally less than 0.2 dB.(3) Tensile strengthFor a good fiber optic connector, the tensile strength is generally required to be no less than 90N.(4) TemperatureGenerally, fiber optic connectors must be able to operate at temperatures between -40oC and 70oC. (5) Number of insertions and removalsThe fiber optic connectors used can be plugged and unplugged more than 1000 times.Connection step1. The Fiber Optic Quick Connector is an innovative field termination connector that includes factory pre-installed fiber, pre-cast ceramic ferrules, and a mechanical splice mechanism.2. When the termination is completed, only the introduction fiber or the indoor fiber can be inserted into the mechanical connection mechanism, without using other tools, the termination process takes only about 2 minutes, which greatly saves the installation time. 3. The ferrule and end face of the fiber optic quick connector are pre-ground and pre-polished at the factory, and the mechanical connection mechanism is located at the end of the ferrule to fix the inserted fiber.4. The mechanical connection mechanism is mainly composed of a V-shaped groove and a clamping element; when a fiber needs to be inserted, the V-shaped groove is opened by a wedge-shaped clamp to facilitate the smooth insertion of the optical fiber.5. When the fiber is inserted into the V-groove and fixed, remove the wedge clamp from the V-groove. In order to facilitate users to better understand and select fiber optic connectors, Konnra Electronics hereby organizes the knowledge and classification of fiber optic connectors, and hopes to be helpful to the majority of users RELATED QUESTION Do I have to acquire some type of license to sell medical equipment on an e-commerce site?
