DC 5V 12V 24V Non Contact Liquid Level Sensor Contactless Water Tank Water Level Sensor for Tank Water Level Control Y25-V High and low level output interface Non-contact level sensor for non-metallic container wall without direct contact with the liquid will not be corrosive acids such as strong acid and alkali corrosion, free from scale or other debris. intelligent level adjustment and liquid level memory function, liquid level status display, multi-point series connection can be achieved; can support high and low level output, NPN output, PNP output, MC output, RS485 data signal output With the manufacturer's instructions can be). detection is accurate and stable, boiling water level can be detected. pure electronic circuit structure, non-mechanical work, stable performance and durable life. High stability, high sensitivity, just interference ability, free from external electromagnetic interference, for the frequency interference and common mode interference have special treatment to be compatible with all available on the market 5 ~ 24V power adapter. Strong compatibility, through a variety of non-metallic containers, such as plastic, glass, ceramics and other containers, sensing distance up to 12mm or more; liquid, powder, particulate matter can be detected. open collector output, wide voltage range (5 ~ 24V), suitable for connecting a variety of circuits and product applications. Intelligent non-contact level sensor is the use of water sensing capacitor to detect whether there is liquid in the absence of liquid proximity sensor, the sensor due to the presence of distributed capacitance, so there is a certain inductor static capacitance, When the liquid level rises slowly approaching the sensor, the liquid parasitic capacitance will be coupled to the static capacitance, the final capacitance of the inductor becomes larger, the change of the capacitance signal is then input to the control IC for signal conversion, will change Of the capacitance into a change in the amount of electrical signals, and then by a certain algorithm to detect and determine the extent of this change, when the amount of change exceeds a certain threshold when the liquid level to reach the sensing point. project name parameter Input voltage (InVCC) DC 5 ~ 24V Current consumption 5mA Output voltage (high level) InVCC Output voltage (low level) 0V Output current 1 ~ 50mA Response time 500mS Working temperature 0 ~ 100 & 8451; Sensing thickness (sensitivity) range 0 ~ 20mm communication RS485 humidity 5% ~ 100% Material ABS Waterproof IP67
