Disposal Method of Capacitive Transmitter on Site(I)

Capacitive transmitters are widely used in petroleum, chemical, metallurgy, electric power, food, paper, medicine, machinery manufacturing and other industries. The product is based on the capacitance dust level measurement principle for the probe and the conductive liquid to form a capacitor, wherein the metal core of the probing line is a pole of the capacitor, the conductive liquid is the other pole of the capacitor, and the middle is a high stability poly Tetrafluoroethylene, the insulating outer layer of the probe wire, serves as the medium between the two electrodes. As the liquid level changes, the area of the liquid surrounding the probe wire changes, causing the relative area of the two electrodes constituting the capacitor to change, resulting in a change in capacitance. .

Capacitive transmitter on-site troubleshooting methods:

1. The transmitter output signal is unstable or assumes a zero output condition. When presenting this situation, it should be considered: the pressure source itself is not stable; the degree of appearance or pressure sensor anti-disturbance; the sensor wiring is not normal; the sensor's own oscillation and fault causes; the polarity of the power supply is reversed.
