Small pipeline level sensor Y26A-V Input voltage (Vin): DC 5~24 V consumption current: 3~8mA output current: 1~100mA response time: 500mS working environment temperature: 0~75 C induction thickness (sensitivity) range: liquid level error:   2mm humidity: 5%~100% waterproof performance: First, product overview The intelligent non-contact liquid level sensor (hereinafter referred to as liquid level sensor) adopts advanced signal processing technology and high speed signal processing chip. It breaks through the influence of the wall thickness of the container, and realizes the real non-contact detection of the level of the liquid level in the closed container. The liquid level sensor (probe) is installed at the upper and lower levels of the outer wall of the measured vessel (high and low level of the liquid level), and the non metal container needs no opening, easy installation and no influence on production. The liquid level of various toxic substances, strong acids, strong bases and various liquids can be detected in high pressure closed containers. The liquid level sensor has no special requirements for the material of liquid medium and container, and can be widely used. XKC-Y26A-xxx series products are specially developed for non-metallic pipeline level detection. This series of liquid level sensors support three kinds of signal output interfaces, which are high and low level output interface, NPN output interface and PNP output interface. The three types of output modes correspond to the following three types respectively: High and low level output interface - model: Y26A -V NPN output interface - model: Y26A -NPN PNP output interface - model: Y26A -PNP Two. Product characteristics Y26A-xxx series sensor, suitable for non metal pipe outer wall without direct contact with liquid, not corroded by corrosive liquid such as strong acid and strong alkali, not affected by scale or other sundries. N intelligent level adjustment and liquid level memory function, liquid level state display mode, can realize multi point series connection; can support high and low level output, NPN, PNP signal output (when type selection and manufacturer's description). The N detection is accurate and stable, and the boiling water level can be detected. N pure electronic circuit structure, non mechanical mode of operation, stable performance and durable life. N has high stability, high sensitivity, strong interference ability and no external electromagnetic interference. It has special treatment for power frequency interference and common mode interference, and is compatible with all 5~24V power adapters on the market. N strong compatibility, through all kinds of non-metallic material container pipes, such as plastic, glass, ceramics and other containers, induction pipe diameter 3~10mm; suitable for various plastic pipe, rubber tube, nylon tube, glass pipe pipe liquid level detection. N wide voltage range (5~24V), suitable for connecting various circuits and product applications. Three. The principle of work The intelligent non-contact liquid level sensor uses the induction capacitance of water to detect the existence of liquid. When there is no liquid close to the inductor, the sensor has a certain static capacitance on the sensor because of the existence of the distributed capacitance. When the liquid level rises slowly close to the sensor, the parasitic capacitance of the liquid will be coupled. To this static capacitance, the final capacitance value of the inductor increases, and the capacitance signal changes again.
