Description
Intelligent non-contact type level detector(Hereinafter referred to level detector) adopts advanced signal processing technology and high speed signal processing chip, break through the effects of vessel wall thickness, realized the real non-contact measurement for the level height in the sealed vessel. Level sensor(probe) installed on the top and bottom(the high level and the low level) of the measuring vessel wall, non-metal vessel do not need to drill a hole, easy installation, good for the production. Can be used for different kinds of toxic, strong acid, strong alkali, and all kinds of level measurement in the high pressure sealed vessel or tank. The application of this product is very wide, no special requirements for liquid media and vessel material.
Features
1: XKC-Y26-xxx series sensor, suitable for non-metal pipe wall, and do not need to contact the liquid, will not corrode by strong acid, strong alkali, and other corrosive liquid. Will not affected by incrustation or other impurities.
2: Intelligent level adjustment and level memory function, level status display method, can realize multi points series connection, can support high and low level output, NPN, PNP signal output.
3: Detection is accurate and stable, can detect boiling water level.
4: Pure electronic circuit structure, non-mechanical work, life durability and stable performance.
5: High stability, high sensitivity, strong interference ability, free from external electromagnetic interference, there are special treatment for frequency interference and common mode interference, compatible with all 5 ~ 24V Power Adapter in the market.
6: Strong compatibility, penetrate various non-metallic container pipes, such as plastic, glass, ceramics and other containers, sensing pipe wall thickness up to 20mm; Suitable for various curve surface, arc-shaped, cylindrical vessel or pipe level measurement.
7: Wide voltage range(5~24V), suitable for connecting various circuits and product applications.
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.
