LEA-400 flat capacitive liquid (material) level switch
Solve various complex working conditionsLow level monitoringQuestion
LEA-400 flat capacitive liquid (material) level switch uses flat metal as one electrode of the capacitor and the container wall as the other pole of the capacitor. When the solution changes, the dielectric constant of the capacitor opens, thereby changing the capacitance. After circuit processing, the liquid level is output. Available forHigh temperature and high pressureStrong corrosion, easy to crystallize, anti-clogging, anti-freezing and solid powder, granular materials. Mainly used for low liquid (material) level monitoring, suitable forEmpty tank monitoring of various tanks, boxes, barns, and silos.LEA-100 useNewpeaceCapacitive level gauge control technology has stable and reliable technical characteristics and is suitable for extreme working conditions.
LEA-100 rod type capacitive liquid (material) level switchIt is a device that converts changes in the position of the measured object into capacitance. The capacitance level meter has the advantages of simple structure, high resolution, reliable operation, fast dynamic response, non-contact measurement, and the ability to work under severe conditions such as high temperature, radiation and strong vibration. It has been used in various fields of industrial and agricultural production.
