Common Faults and Solutions of Pressure Transmitters
1. Abnormal output signal: Check whether the power supply is normal, the wiring is correct, and the sensor is damaged.
2. Zero drift: It may be caused by temperature change, and zero calibration is required; check whether the installation position is correct.
3. Large measurement error: Check whether the range setting is correct, whether the sensor is contaminated or damaged, and whether there is leakage in the pipeline.
4. Unstable signal: Check whether the wiring is loose, whether there is electromagnetic interference, and whether the medium has pulsation.
5. No output from the transmitter: Check whether the power supply is normal, whether the wiring is disconnected, and whether the sensor is damaged.
Regular maintenance and calibration are the keys to ensuring long-term stable operation of pressure transmitters.
