Features CORROSION RESISTANCE The level sensor is not corroded by strong acids and alkalis as well as other corrosive liquids and is not affected by deposits or other small items. Pure Electronic Circuit Structure The liquid level sensor is precise and stable in detection, pure electronic circuit structure, non-mechanical working mode, stable performance. Application scenario: the non-contact level sensor is suitable for use on the outer wall of non-metallic pipes without direct contact with the liquid. Various Parameters The non-contact level sensor has NPN output, 500ms response time and input voltage of 5V DC. Liquid Level Memory The sensor has intelligent liquid level reference setting and liquid level memory function, as well as liquid level status display mode, and can realize multiple points of series connection. Specification: Item Type:Non-contact Liquid Level Sensor Material: PC. Model: XKC Y21 NPN Power consumption: ±8 mA. Output mode: NPN Response time: 500 mS. Ripple and noise voltage: <1000 mvpp. Accuracy of liquid level: ±3 mm. Environmental certification: ROHS 2.0 Input voltage: DC 5 V. Output current: ≤ 100 mA. Operating environment temperature: -20 to 75 °C. Range of detection thickness (sensitivity): ≤5 mm. Package list: 1 x water level liquid sensor. Note: 1. Double-sided foam wool adhesive must not be used. 2. The container material must be insulating material. 3. Try to use a uniform material without air intermediate layer, without air bubbles and non-absorbent. The dielectric constant does not change the material for the container easily.
