RF Admittance Level Switch

UVCR RF Admittance Level Switch is a new product developed from capacitive level switch.Anti-hanging material (the material adhered by the sensor is called hanging material) has better performance, more reliable work, more accurate measurement and wider applicability.The meaning of "admittance" in "RF Admittance" is the reciprocal of impedance in electricity.It is composed of capacitive reactance 、impedance and inductive reactance. And "radio frequency" is high frequency,Therefore, radio frequency admittance technology can be understood as a method of measuring admittance with high-frequency current.

The important difference between RF admittance technology and capacitance technology is that it adopts three-terminal shielding technology and the diversity of measurement parameters, which not only solves the problem of parasitic capacitance temperature drift of connecting cables, but also solves the problem of sensor hanging.

Features

• Advanced three-terminal shielding technology, strong anti-hanging ability.
• Circuit design of wide power supply, universal AC/DC power supply.
• Built-in 1000V spark protection, strong anti-interference ability.
• Integrated structural components, no blockage and need not maintain.
