The transmitter is an important part of the whole industrial automation system, and the pressure transmitter is mainly used for the measurement of gauge, absolute and negative pressure in the gas, liquid or process industry. With the application range of pressure transmitter is becoming more and more extensive, the problems encountered in the use process are becoming more and more apparent, do not panic when encountering pressure transmitter failure, the following teaches you how to quickly identify and solve the fault problem of pressure transmitter. Don’t panic when you encounter a pressure transmitter failure, teach you how to solve it quickly: Fault 1: The pressure source goes up, and the output of the pressure transmitter does not change with it. First of all, check whether there is air leakage or blockage at the interface of the pressure transmitter. After checking this item, no After the problem, check whether the pressure transmitter is wired in the wrong way. A lot of the time it’s a problem with the wiring. When the wiring is correct, it is necessary to simply apply pressure or check whether there is an output at the zero position of the pressure transmitter. If there is no change, the pressure transmitter is damaged, if there is, the pressure transmitter problem is ruled out, and the problem needs to be looked at other parts of the overall work system. Fault 2: Delay in pressure value change. If we encounter pressurizing the pressure transmitter during the use of the pressure transmitter, the output of the pressure transmitter does not change; Repressurization, sudden change in pressure transmitter output; The pressure transmitter does not return to the zero position after the pressure is relieved. This is the problem with the seals of pressure transmitters. Due to the non-compliance of the seal of the pressure transmitter, after its installation, the seal is compressed into the pressure transmitter inlet, thus blocking the pressure transmitter. Fault 3: The output signal of the pressure transmitter is unstable In this case, we need to make sure that the stressor is unstable. Then, the interference equipment on the site is investigated to avoid the occurrence of large interference power equipment at the use site of the pressure transmitter. Finally, it is necessary to see whether the pressure transmitter is not strong in anti-interference ability, or has been damaged by surge or pulse impact.
