Level Switch
CRF312 Ultra High Temperature RF Admittance Level Switch
The electrode rod of RF admittance level switch consists of measuring electrode, shielding electrode and grounding electrode. These three kinds of electrodes are isolated by insulating material. When the media touches the measuring electrode the admittance between the measuring electrode and the grounding electrode will increase and the media level changes can be judged by the change of admittance.
