NK-24120 Vertical Stainless Steel Liquid Water Coolant Level Sensors for Truck Tank

Operating principle:

The water level detector adopts built-in frequency discrimination detection chip IC. The level signal sends from input end with level inductive surface which is isolated by insulating plastic casing. But because of the frequency discrimination function of chip, it can still detect level out of casing and then output an accurate potential signal, with water high potential, without water low potential. The product is called Full Sealed Inductive Level Sensor. Moreover, output end of chip can also mount a switch as a level switch or level automatic controller, detect and control by itself, plug and play.
