RF Admittance Level Switch

Product Description

RF Admittance Level Switch


RF Admittance Level Switch JCRF series adopts advanced RF admittance technology and overcomes the defects that the capacitor level switch could not eliminate the effect by conductive hanging material. The instrument operates reliably and various technical indexes have archived the international level, which is widely used in control and alarm of liquid, pulp, powder, material level and two different liquid levels. In addition, this product have status indication at site, it is a high cost performance and stable level sensor.


RF Admittance Level Sensor RF series consists of sensor unit and electronic unit. The sensor unit mainly includes three parts: measurement probe, shaded pole and ground terminal. The material level is reflected through the change of admittance between the probe and vessel wall. When the level reaches to the switch working point, the electronic unit makes response and driver replay acts,

thus output switch signal. The shaded pole can prevent fault signal generated due to the handing on the electrode from occurring.Only when the level actually archives the set point can the switch control signal be output.
