In the air compressor, the pressure transmitter will be used, but in the process of mechanical operation, the air compressor pressure transmitter will produce the phenomenon of unstable output signal, today I will answer the cause of the failure. Fault 1: The pressure of the air compressor pressure transmitter can go up, but the output of the transmitter cannot go up In this case, you should first check whether the pressure interface is leaking or blocked, if it is confirmed, then check whether the wiring method is wrong and check the power supply, if the power supply is normal, you should simply pressurize to see if the output changes, or check whether the zero position of the pressure transmitter has output, if there is no change, the transmitter has been damaged, otherwise the instrument is damaged or other links of the whole system. Fault 2: The output signal of the air compressor pressure transmitter is unstable This failure can be considered a problem with the stressor. The pressure source itself is an unstable pressure, and it is likely that there is interference from high-power equipment in the environment where the instrument or pressure transmitter is used, the transmitter itself is vibrating badly, or the transmitter is damaged. Fault 3: The problem of the sealing ring of the air compressor pressure transmitter The pressure transmitter of the air compressor is pressurized for the first time, the output of the transmitter does not change, and the output of the pressurized transmitter changes suddenly, and the zero position of the transmitter cannot be returned after the pressure is relieved, which is likely to be the problem of the sealing ring of the pressure transmitter. It is common for the pressure transmitter to be compressed into the pressure intake port of the transmitter after the pressure transmitter is tightened due to the specification of the sealing ring, thus blocking the air compressor pressure transmitter.
