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.
XKC-Y26-V products specifically for the development of non metal pipeline level detection.
Two, product characteristics

N strong compatibility, through a variety of non metal materials of the container pipe, such as plastic, glass, ceramics and other containers, the wall thickness of the induction tube20mmThe liquid level detection of a container or a pipeline which is suitable for various surfaces, arcs and cylindrical vessels.
N wide voltage range5~24V), 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.

Five, Application conditions
(a) the measured liquid medium viscosity
Dynamic viscosity<10mPaSTime normal measurement.10mPaS<Dynamic viscosity<30mPaSMay affect the detection. Dynamic viscosity>30mPaSWhen a large amount of liquid is attached to the vessel wall, it can not be measured.
Note: with the increase of temperature viscosity decreased, most of the high viscosity of the liquid temperature effect is more obvious, so the viscosity of liquid in the measurement of attention to the effect of liquid temperature.

1,Form top
Pay attention to the cleanliness of the liquid level gauge, try to prevent corrosion and avoid violent collision of other objects, blow.
Outdoor installation should avoid direct sunlight level meter main body, away from the heat source and pay attention to ventilation, if the ambient temperature exceeds the rated temperature, should take appropriate measures to protect the cooling.
When the environment temperature is too low, the instrument can be used to protect the box or other protective device for anti freezing protection, and pay attention to keep the level of dry.
The sensor should be regularly maintained and checked. (inspection interval is determined by the use of the unit according to the specific circumstances).
