RF Admittance Level Switches
Our RF level switch is widely applied in various products such as Building industry materials, cement, sand, lime, milk powder, flour, salt, food grains, powder, granular, chemical and mining etc. These comprise of a specially designed electronics and sensing probe using Driven Shield Coat Guard circuit and corresponding 3-Element Probe.
The electro-mechanical combination of the Coat Guard technique is there makes the system immune to the material build-up on the probe and material bridging between the probe and the hopper wall. The measured signal does not flow to the hopper wall through the probe in the backward direction but flows only through the material.
The salient features of this level measuring instrument are as follow:
