What is the voltage between electrodes of the Floatless Level Controllers "61F"?


Between the level electrode and the common electrode, when they do not soak in the liquid the voltage is about 7-8VAC. When they soak in the liquid the voltage decreases to about 0V according to the specific resistance of the liquid. Therefore, when the 61F is individually inspected, be sure to measure the voltage between their terminals by leaving the electrodes open.

In the case of a high-sensitivity model, that with 24VAC is also available.
