RF capacitor level switch

Product Overview

The UDE-508 series RF capacitor level switch is an intelligent level instrument. The product adopts RF capacitance measurement technology and digital calibration technology, which solves the two major problems of large temperature drift and difficult calibration of capacitive level switches in use for a long time. Especially the innovative design of "digital calibration technology" brings great convenience to users' use. It will further promote the wider application of capacitive level switches in various industries.
This product is easy to operate, just press the setting button to set the upper or lower limit; The control method is flexible, and users can choose between normally open or normally closed contacts. Can overcome the influence of adhesive layer and material splashing on measurement on the probe. In these situations, capacitor switches will not cause misoperation. Due to the absence of movable components in the detection area, it is impact resistant. The probe insulation is made of PTFE, which can withstand temperature, voltage, corrosion, and is not easily adhered.

structural principle

The sensor probe is installed on the top or side wall of the container, forming a capacitor between the probe and the container wall. When the medium is air, and the liquid level or material rises to bury the probe, the dielectric constant between the probe and the container wall changes, and the capacitance increases. The electronic circuit detects the increase in capacitance and outputs a switch value for alarm or control.
