Product Overview

CWA small intelligent capacitive liquid level switch, with a simple structure,Without a mechanical transmission structure, it will not cause mechanical wear, has a long service life, is easy to install, and has simple debugging. The new intelligent digital circuit design has high precision and good stability, improving the user's range of use and easily handling measurements of different materials. Software function optimization and improvement to meet the vast majority of solid needs/Body fluid measurement (including viscous materials) can be calibrated with just one click to set the appropriate alarm position; An additional operator can be used to view the measured values in real time and modify the matching alarm values. In addition, the delay value, hysteresis value, and high/low alarm switching can be modified to meet the usage needs of working conditions that cannot be applied.

Technical Features

At the bottomUnrelated to material density, suitable for use in conductive applications/Switching control of non-conductive liquids and solid particles

Ø Can be used in harsh environments such as high pressure, vacuum, high temperature, low temperature, strong vibration, and strong corrosive liquids

Ø Compact size, simple structure, good dynamic performance, high sensitivity, and strong resolution

Ø No movable parts during operation, reliable operation

working principle

CWA Small Intelligent Capacitive Liquid Level SwitchBased on the capacitance formed between the sensing electrode and the ground electrode,

To beThe measured material is a medium. When the material covers the sensing electrode, the measured capacitance value will increase and reach the set value

Output a switch signal when the value is reached.

C = ( 0.0884 × K · A) / TD

K =dielectric constant
