Product Name: Capacitive Liquid Level Switch
BS-DFA RF Capacitance Level limit switch (the limit switch) using the "RF" and "digital calibration technique" to solve the long-Capacitance Level limit switch in the use of drift, which is difficult calibration of the two major problems, so that capacitive level limit switch for applications made breakthrough progress. Especially the "digital calibration technique," is home and abroad. It will promote the capacitive level limit switch is more widely used in industries.
