Diffusion silicon pressure transmitter common troubleshooting
1. During installation, the pressure sensitive component of the transmitter should be perpendicular to the direction of gravity. If the installation conditions are limited, the transmitter zero position should be adjusted to the standard value after installation.

2, the residual pressure can not be released, so the zero position of the sensor can not come down. The reason for eliminating this cause is to remove the sensor and directly check whether the zero position is normal. If the zero position is normal, replace the seal and try again.
3. The output of the pressurized transmitter does not change, and the output of the pressurized transmitter suddenly changes, and the pressure relief transmitter can't go back. The cause of this phenomenon is most likely caused by the pressure sensor seal.
4. Whether it meets the power supply requirements; there is no wiring error between the power supply and the transmitter and the load device. If there is no voltage on the transmitter terminal or the polarity is reversed, the transmitter can output no voltage signal.
5. The outer casing of the pressure sensor and transmitter should be grounded. The signal cable should not be mixed with the power cable. Strong electromagnetic interference should be avoided around the sensor and transmitter. Sensors and transmitters should be periodically verified in accordance with industry regulations during use.
6. When selecting the pressure sensor and transmitter, the user should fully understand the working conditions of the pressure measurement system, make reasonable selection according to the needs, make the system work in the state, and reduce the project cost.
7. Transfer to the sides of the measuring diaphragm through the spacer and the filling liquid in the component. The measuring diaphragm and the electrodes on the insulating sheets on both sides each constitute a capacitor.
8. The pressure transmitter is required to be inspected once a week, once a month. It is mainly to remove the dust inside the instrument, and carefully check the electrical components. The current value of the output should be checked frequently. The pressure transmitter is weak inside. It must be separated from the outside world by strong electricity.
