Let's take a closer look at the problems that arise during the calibration of the pressure transmitter and how to solve them. Let me take you to know about it later. 1. Internal failure of the transmitter Because the production process of the transmitter is very complicated, there are situations in which the transmitter cannot work normally due to the unreasonable setting of the internal parameters of the transmitter, resulting in the failure of the entire system to operate normally, the switch tripping and other problems. Therefore, before using the transmitter, the internal parameters and standard parameters should be accurately calibrated to ensure the rationality of the transmitter parameter settings. The device can test normally. 2. Transmitter overload problem The transmitter may have overload problems during the working process. The overload of the transmitter will cause the internal current of the transmitter to increase, which will cause the temperature of the internal components of the transmitter to be high, which will affect the verification results. At the same time, it will reduce the service life of the transmitter. If the internal current is too large, the transmitter will be burned, which will not only affect the normal verification of the transmitter, but also bring huge potential safety hazards. In order to solve the overload problem of the transmitter, it is necessary to check the maximum load and pressure of the circuit before the transmitter is calibrated to minimize the occurrence of overload. In addition, it can also reasonably prolong the verification time, reduce the maximum current in the transmitter, and control the heating of the transmitter components. In the process of transmitter verification, it is necessary to arrange relevant professionals to maintain it to ensure the lubricity of its contact surface, eliminate hidden dangers, and provide guarantee for the normal verification of the transmitter. 3. Gas leakage If the precision of each part of the pressure transmitter is insufficient, it will lead to the leakage of internal gas during operation, which will not only affect the normal verification of the equipment, but also threaten the personal safety of the staff. When this happens, the staff needs to immediately reduce the air pressure to a suitable level, but the air pressure should not be too low, which will cause the transmitter to fail to perform normal verification. In order to avoid this situation, the transmitter components should be strictly screened before the installation process, and high-quality equipment materials should be used to minimize the probability of transmitter gas leakage. 4. Internal leakage The internal discharge fault caused by the poor insulation of the insulating material is one of the factors affecting the normal verification of the pressure transmitter. Therefore, when selecting transmitter components, it is necessary to select raw materials with good insulation properties. At the same time, it is necessary to pay attention to the cleaning of the equipment during use to reduce the probability of leakage. 5. Pressure transmitters are widely used in various industries and are bound to be distributed in various parts of the country, and the pressures are different in different places. The actual pressure of the transmitter's verification environment is likely to be different from the required standard atmospheric pressure, which will Interfere with the verification, making the final result inaccurate. Typically, the solution to this problem is the range shift method. The specific operation process is as follows: First, connect the pressure transmitter and the communicator to the verification system, the communicator will display the air pressure reading of the verification environment, and then use the communicator to change the upper and lower limit settings of the transmitter, namely The current upper and lower limit values u200bu200bare the sum of the original upper and lower limit values u200bu200bof the transmitter and the current air pressure value. Then, perform normal verification work. After the verification, restore the transmitter to the initial state, that is, the current upper and lower limit values u200bu200bare the difference between the new upper and lower limit values u200bu200bminus the current air pressure value. 6. Safety issues of on-site verification Because the use of pressure transmitters is mostly in various industrial sites, such as natural gas, oil and other construction sites. These places need to be strictly explosion-proof and anti-static, otherwise, there will be great safety hazards. Therefore, when carrying out the verification work, it is necessary to do a good job of safety protection, and to monitor the verification environment in real time to ensure the safety of the verification work. 7. The problem of weak inspection supervision During the inspection process, effective control measures must be taken, and relevant professional and technical personnel must be supervised during inspection. Before the verification, pre-experiments can be done in advance to improve the proficiency of the verification personnel, and to avoid the operation errors of the verification personnel during the verification process due to their unfamiliarity with the verification process. In order to ensure the accuracy of the verification results, repeated inspections can be carried out several times if necessary, and timely feedback should be given if there is a large error. I hope the above content can help you. If you have found any problems that have not occurred in the process of use, please feel free to call to inquire and solve the problem.
