Product principle
LS380 series adopts capacitive principle sensor for liquid level measurement, and the signal is converted into standard industrial electrical signal output and display after processing by the rear processing circuit. Capacitive sensor built-in electrode and metal tank or box to produce capacitance value, capacitance value with the increase and decrease of the medium in the cavity changes, so as to determine the liquid level of the medium.
