1. Product overview Intelligent non-contact liquid level sensor (hereinafter referred to as liquid level sensor) adopts the advanced signal processing technology and high speed signal processing chip, broke the influence of container wall thickness, Y29A series capacitor sensor is designed by non-metal container wall detection of liquid level, it can automatically adapt to a certain thickness of plastic or glass wall (container wall thickness up to 10mm), realizes the height of liquid level in the closed container real contact detection. The liquid level sensor (probe) is installed on the upper and lower part of the outer wall of the tested vessel (high and low level of the liquid level). The non-metal container does not need to be opened and easy to assemble the whole machine. The XKC-Y 29A series of products is developed for container level detection of non-metallic materials, in the medical, food and beverage, agriculture and water treatment industries. This series of liquid level sensors has two signal output control modes, namely high and low level output interface and NPN output interface; the two signal output modes correspond to the following two models: order number model signal interface 

2. product features 1. The XKC-Y29A series is a non-contact level sensor that automatically calibrates the level sensitivity in the form of buttons. 2. Can support high and low level output, NPN (selection and manufacturer instructions). 3. The detection liquid level is accurate and stable, and the cold, hot and boiling liquid can be detected. 4. Pure electronic circuit structure, non-mechanical working mode, stable performance, long continuous service life. 5. High stability, high sensitivity, strong anti-interference ability, not by external electromagnetic interference, for power frequency interference and common mode interference has done special treatment.

6. The power supply is equipped with reverse connection protection, short circuit protection, overcurrent protection and overvoltage protection; compatible with all 12-24V power adapters on the market. 7. used in medical and food industries, with strong induction ability, can penetrate and detect the liquid level of various non-metallic containers, such as plastic, glass, ceramic and other containers, induction distance (container wall thickness) up to 10mm; liquid, powder, particles can be detected. 8. Open collector output mode, wide voltage range (12-24V), suitable for connecting various circuits and product applications. 3. major function 1. Detection of water-based fluid in flat containers, water-based solvent. The liquid level in the container or pipe can be detected without direct contact with the medium itself. 2. It can reliably detect the medium, with high stability; compensate for the residual water, milk, honey, latex, body fluids (blood), acid or alkaline solution in the container, to achieve the function of actual differentiation level. 3. Black line can replace the sensor button calibration function, play the role of remote calibration sensor sensitivity.
