RF Admittance Level Switch

RF admittance level switch is a level sensor used for point-level detection of liquids, solids, or slurries in industrial processes. RF admittance level switch offers reliable and accurate level sensing, making it valuable in diverse industries like chemical processing, water treatment, and food production.

Feature

• Easy installation and debugging: Fully sealed integrated installation structure, all using digital integrated circuits, without any mechanical movable parts. Once installed, zero calibration does not require repeated debugging.
• Low temperature drift: Using digital electrical appliances, compared with existing products, the impact of ambient temperature and humidity on the instrument is greatly reduced, and no zero adjustment is required when changing seasons. The advanced circuit design can avoid false signals caused by material adhering to the probe, and can resist the effects of various fluctuations.
• Strong on-site adaptability: This radio frequency admittance level switch can detect solid and liquid materials in high temperature, high pressure, large dust, and high viscosity situations.
• One-time zero calibration: Due to the use of digital circuits, users can complete zero calibration at one time in a short position.

Tips: What is the working principle of RF admittance level switch?

A Radio-Frequency (RF) admittance level switch operates based on the principle of measuring the change in admittance as a probe comes into contact with a material. Admittance is the reciprocal of impedance, and it includes both conductance and susceptance. In this level switch, an RF signal is emitted from a probe, and as the material level rises, the capacitance between the probe and the material changes. This alteration in capacitance leads to a change in admittance, which is detected by the instrument. The switch triggers when the admittance reaches a predefined threshold, indicating the material has reached a specific level. This technology is commonly used in industries to monitor and control levels of liquids and solids in tanks and vessels, offering a reliable and accurate solution for various industrial applications.
