the liquid level sensor of the oil tank and water tank adopts the principle of magnetic field to control the spring pipe electrocution on and off, converts the change of the measured liquid level into electrical signal output and connects with the instrument, so as to detect the height of the liquid level.
The level sensor’s Length 325mm, the resistance of full oil is 13Ω,the resistance of bottom is 120Ω , connector : DJ7021Y-1.5-11
Length can be customized to customer tank height.
