JCL-16XX of Double capacitance liquid level sensor

Main features


Accurate linearity and temperature compensation technology to avoid test errors caused by temperature changes;Suitable for testing various non-conductive liquids; No calibration is required according to the test liquid; The measuring range can be customized according to customer's requirements, and the flange structure can be customized. There is no need to calibrate the detection liquid, and one calibration can be applied to the detection of different liquids; The problem that the capacitance liquid level sensor is easily affected by temperature is solved.It is suitable for liquid level measurement in high temperature field. 


Summarize


The double capacitance self-compensation principle is adopted to solve the problem that the traditional capacitive liquid level sensor is easily affected by temperature and medium, improve the detection accuracy and stability of the sensor capacitive liquid level sensor, and realize high-precision liquid level measurement under temperature change and medium change. There is no need to calibrate according to the test liquid! Capacitive liquid level transmitter adopts a coaxial capacitor, which consists of two coaxial cylindrical polar plate inner electrodes and outer electrodes. When liquid enters the container, the capacitance value between the sensor shell (outer electrode) and the sensing electrode (inner electrode) changes to output a liquid level signal, which is suitable for measuring various liquids.
