The RF radio frequency conductivity level switch is a continuous level measurement product based on the principle of radio frequency conductivity. The product has the advantages of high stability, high sensitivity, and a wide range of applications. Compared with the traditional capacitance level meter, it adopts modular design, which can realize the instrument setting concisely and conveniently, and once the setting is completed, it can be used normally and maintenance-free for life.

RF-conductivity technology incorporates Driving-Shield circuitry and chopper circuitry in the electronics unit, thus enabling separate measurements of impedance and capacitive reactance.

Radio Frequency Conductivity (RFCC) technology is one of the most widely used measurement technologies because of its high accuracy and the fact that it is not affected by the material hanging on the probe. From low temperature -100 ℃ to high temperature 800 ℃, from the vacuum to 6.3MPa strong pressure occasions, from the ultra-short range to 120 metres of large range, can be normal application, and can be applied to different types of materials.
