Intelligent non-contact liquid level sensor use the water induction capacitor to detect the liquid.When no liquid approach the sensor,the sensor has the certain static capacitance to the gound due to the distributive capacitance exist.When the liquid level rise and close to the sensor,the liquid's parasitic capacitance will be coupled to the static capacitance then enable the sensor's capacitance increase and the changed capacitance signal will be imported into the controlling IC to coverter it into some signal viration, use some algorithm to detect and judge this singal viration level, when this signal viration excess certain values will be considered the liquid level reach the detecting point.
Applicable to non-metallic containers without direct contact with the liquid, not affected by scale or other impurities.
Intelligent liquid level benchmark adjustment and level memory function, liquid level display mode.
Electronic circuit structure rather than machinery ensures stable performance, durability and a long service life.
High stability, high sensitivity, strong anit-interference ability make sure it won't be affected by electromagnet, special designed to deal with power frequency interference and common mode interference
NPN signal output, where sensor the liquid, it will output low level otherwise there is not signal output.
