Radio frequency admittance level switch

First, the working principle

Electrostatic capacitive material level switch is the use of material level switch probe (induction) and bucket wall (grounding electrode) as two plates of capacitor, when the medium between the two plates of capacitor changes, its capacitance change, also test the change of position switch analysis processing unit size, when the change value to switch Settings, which convert switch signal output, For controlled use, thus reflecting the height of the medium or liquid interface to be measured.

Two, product features:

1. The action is stable when the adhesive medium is measured

2, conductive, non-conductive medium can be used

3. Convenient detection of strong corrosive liquid

4, no moving parts, good mechanical strength

5, convenient installation, simple debugging
