Capacitance level switch
Feature
Capacitance level switch use “one key calibration” technology, resolve the difficult issue which capacitance level switch calibration cumbersome in use process. Capacitance level switch can be used for bulk, grain, and powder, liquid. And it have upper and lower limit alarm, can be used at high temperature, high pressure, strong corrosion, dust, ultrafine particles environments. It also be widely used in metallurgy, petroleum, chemical industry, light industry, coal, cement, food industries.
Principle
The probe of the level switch and the tank side can be as a cpacitor, the capacitance changed based on the medium. Applied a high-frequency signals on the probe, there will be a small current through the media back to the sides of tank. The medium change on the probe, will cause high and low current change.
