First, product overview
Non contact type liquid level sensor (hereinafter referred to as the intelligent liquid level sensor) using advanced signal processing technology and high-speed signal processing chip, break through the influence of the wall thickness, the height of the liquid level in the sealed container real non contact detection. The liquid level sensor (probe) is installed in the upper and lower part of the outer wall of the tested container (high and low liquid level), and the non metal container does not need to open the hole, and the installation is simple and does not affect the production. The liquid level can be realized on the high pressure sealed container of toxic substances, acid and alkali and other liquids were detected. The liquid level sensor has no special requirements for the material of the liquid medium and the container, and can be widely used.
Intelligent non-contact liquid level sensor is divided into four kinds of signal output interface, which are high and low level output interface, NPNOutput interface,PNP output interface,RS485Interface, respectively, corresponding to the four models:(please note that the customer to buy a good thank you!)
High and low level output interface - type:XKC-Y25-T12V
NPNOutput interface model:XKC-Y25-NO (NPN)
PNP output interface - model:XKC-Y25-NO (PNP)
RS485Interface model:Y25-RS485 XKC-

N open collector output, wide voltage range (5~24V), suitable for connecting all kinds of circuit and product application.
Three, working principle
The intelligent non-contact liquid level sensor is induction capacitor use of water to detect whether liquid exists, no liquid in proximity sensor, the sensor because of distributed capacitance, so the inductor to exist certain static capacitance, when the liquid level rises close to the sensor, the parasitic capacitance will be coupled to the static liquid the capacitance, the capacitance sensor value becomes large, the change of the capacitance signal input to the controlICSignal conversion, the variation of the capacitance will change into a signal, and then by a certain algorithm to detect and judge the change degree, when the change exceeds a certain threshold that the liquid level reaches the induction point.
