PNP Output Interface Outer Adhering Type Contactless Water Level Switch Detector Liquid Level Sensor
This is a Intelligent contactless liquid water level sensor detector,using an advanced signal processing technology and high speed signal processing chip.
Detecting the liquid level of various liquids,especially like the toxic substances, strong acids, strong bases,even not affected by the liquid vessel wall thickness,really non-contact detection.
This liquid water level sensor detector can work with any kinds of liquid and its metalloid container vessel .
Features:
Ntelligent level adjustment and memory function for the liquid level

Working principle
Intelligent non-contact level detector is using water detection capacitance to detect whether the liquid is present,
when there’s no liquid access to the detector,there’s static capacitance due to distributed capacitance exist in the detector,
when the level rise and close to detector, the stray capacitance of the liquid will couple to this static capacitance,make the final capacitance value of the detector become bigger,
this changing capacitance signal input into IC to convert the signal, making the changing capacitance convert to some changing signal,
and then by a certain algorithm to detect and determine the extent of the amount of change,
when the change exceeds a certain threshold level reaches the sensor point.
