Common fault types of pressure transmitters!

Pressure transmitters will inevitably have various failures during use, and their influencing factors are numerous. The following editor of Wo Tian introduces several common types of failures and hopes to help everyone.

1.Line failure: When a line failure occurs, the computer displays an abnormal value. Open the transmitter junction box, and check whether the circuit has a virtual connection, short circuit, or disconnection. The power supply, shake insulation, and resistance measurement And other methods for troubleshooting;

2.The output signal is zero: first check whether there is pressure in the pipeline, whether the meter is normally powered, Taiwan pressure transmitter, then check whether the polarity of the power supply is reversed, and finally check the electronic circuit board, pressure sensing film head, Transmitter power supply voltage, etc .;

3.There is no response under pressure: If there is no response under pressure, check whether the valve of the pressure taking pipe is normal, whether the jumper switch of the protection function of the transmitter is normal, whether the pressure taking pipe is blocked, check the zero point and range of the white feeder, and replace the transmission. Sensing film first class.

Nanjing Wotian Technology Co., Ltd. was established in 2005. It focuses on the production of pressure sensors. It is a domestic heavyweight pressure sensor manufacturer. It has the core technology of diffusion silicon pressure sensors and glass micro-fused pressure sensors. More than 1.5 million silicon pressure sensors are exported to more than 70 countries and regions. The company has factories in Nanjing and Anshan, and its headquarters is located in the scenic Nanjing Jiulonghu International Headquarters Base.

Nanjing Wotian Technology Co., Ltd. is a "high-tech enterprise", "Nanjing Engineering Technology Research Center" and "Nanjing Postdoctoral Innovation Practice Base".
