EHC-3,4

製品名EHC-3,4

Mounted on the top cover or other places of a water tank, and has stainless steel electrodes with different lengths
Detects the water level when a resistance value changes when water comes into contact with the electrodes with different lengths, which then send signals to the main unit of the level switch
