Pressure sensors are the most commonly used sensors in industrial practice and are used in a variety of industrial automation environments. However, for novices, we often encounter the inspection problem of the pressure sensor line in use, and many users do not know what to do. The following small series will introduce you to check the line problem of the pressure sensor. The pressure sensor is plugged in, and after the input pressure signal is given, the status of the voltage signal at the output of the pressure sensor is checked. If there is no voltage or the polarity is reversed on the pressure sensor terminal, it can cause the pressure sensor to have no voltage signal output. To rule out the above reasons, you should further check whether the components in the amplifier board circuit are damaged; Whether the circuit board connector has poor contact phenomenon, determine the fault point, and replace the faulty amplifier board if necessary. Pressure sensor in the line design and process assembly quality requirements are very strict, in the actual use of the line failure, after inspection and confirmation, it is best to contact the manufacturer to replace its faulty circuit board to ensure the stability and reliability of the long-term work of the instrument.
