1. The pressure of the 3051 transmitter does not go up to the output of the transmitter, the output of the pressurized transmitter does not change, and the output of the pressure transmitter changes suddenly, and the zero position of the pressure relief transmitter cannot be returned.
In this case, you should check whether the pressure interface is leaking or blocked, check the wiring method and power supply, if it is normal, then check whether there is an output at the zero position of the sensor, or simply pressurize to see if the output changes, if there is a change, the sensor is not damaged, if there is no change, the sensor has been damaged. Finally, it may be the appearance of the damage, or the other parts of the whole system.
2. The output signal of the 3051 pressure transmitter is unstable
In this case, it should be considered that the stressor itself is an unstable pressure; The appearance or pressure sensor is not strong in anti-interference; The sensor is not well wired; The sensor itself oscillates badly, and the E. sensor is malfunctioning.
3. The output of the pressurized transmitter does not change, and the output of the pressurized transmitter changes suddenly, and the zero position of the pressure relief transmitter cannot be returned.
However, when the pressure is very high, the sealing ring is suddenly opened, and the pressure sensor is changed by pressure, and when the pressure drops again, the sealing ring returns to block the impulse port, and the residual pressure cannot be released, so the zero position of the sensor cannot be lowered. The way to rule out this cause is to remove the sensor to see if the zero position is normal, and if so, replace the seal and try again.
