Contactless intelligent type level detector adopts advanced signal processing technology and high-speed signal processing chip, breaking the effects of vessel wall thickness, made the measurement real contactless for the level height in the sealed container. Level sensor installed at the top and bottom of the measuring vessel wall, the non-metallic container does not need to drill a hole, easy installation, good for production. It can be used for different types of toxic, strong acid, strong alkaline, and all kinds of level measurements in the sealed vessel or high pressure tank. The application of this product is very wide, there are no special requirements for liquid media and container material. 1: XKC-Y26-PNP suitable for non-metallic pipe wall, and does not need to contact the liquid, it is not corroded by strong acid, strong alkaline and other corrosive liquid. It will not be affected by embedding or other impurities. 2: intelligent level adjustment and level memory function, level status display method, multi-point serial connection can be performed, It achieves the contactless detection of the liquid level in the closed container;The liquid level sensor is installed on the upper and lower sides of the container (the liquid level is high and low);The non-metallic container does not need to open the hole;It can detect the level of various toxic substances, strong acids, alkalines and various liquids in high pressure airtight containers The liquid level sensor has no special requirements for the type of liquid and container materials and can be widely used. Installation is simple and does not affect production. The output signal is the PNP signal. The specifications: Product model: XKC-Y26-PNP Input voltage (input): DC 5-24V Warning output signal: PNP Current Consumption: 5mA Output voltage (high level): input Output voltage (low level): 0 V Output current: 1 ~ 100mA Response Time:
