transmitterIt is one of the widely used instruments in industrial production, and many physical parameters can be measured through it, such as pressure, liquid level, and flow rate, which are of great significance for industrial production.

　　transmitterThe pressure indication is abnormal, which is related to factors such as reference pressure value, power supply, wiring, temperature, etc. To solve the problem of abnormal pressure indication, we need to do it.

1. Inaccurate reference pressure values can also cause abnormal pressure readings. So, we need to choose a reference pressure gauge with higher accuracy.

2. Check if the power supply of the pressure transmitter is normal and ensure that there is no significant load input in the circuit.

3. The wiring is incorrect. The wiring at the output of the pressure transmitter varies depending on the input of the pressure indicating instrument. Some transmitters can use direct input wiring, while others require connecting a resistor before connecting to the input.

4. The influence of temperature. When the temperature of the pipeline in the pressure transmitter is too high, it will affect the normal use of the pressure sensor, leading to the occurrence of faults. Therefore, it is necessary to strictly control the operating temperature of the pressure sensor and maintain it within -20~70 ℃.

4. Blockage of foreign objects. Once the pipeline of the pressure transmitter is invaded by foreign objects, it will cause blockage of the pipeline and result in abnormal pressure display values of the transmitter.

5. The device casing is not grounded. The solution to this problem is very simple, just ground the outer shell of the device.

The above is the summary and sharing of today's article on solving the problem of abnormal pressure indication of the transmitter. We hope it will be helpful for everyone to use this device in the future.
