Trumsense DC 12 to 24V Power Supply WS02 WS03 Capacitive Type Contactless Liquid Level Sensor For Flat Container or Pipes

This product can only be installed in non-metallic containers or pipes, such as plastic, glass, or ceramic. Mounted on the outer wall of the container, it avoids direct contact with the measured liquid and is not susceptible to corrosion from strong acids and bases, nor to scale. To adjust the sensor's sensitivity after installation due to varying container thicknesses, remove the QC label, secure the sensor to the container or pipe, adjust the liquid level to the desired sensing position, and then press and hold the button in the small circular hole for approximately 3 seconds until the blue status indicator flashes. Release the button. The sensor will then sense the liquid level as it approaches the desired level.


This non-contact liquid level sensor operates with a wide voltage range of 5 to 24V DC. The switch output voltage is equal to the supply voltage. The connected device port must be able to withstand this voltage to avoid damage.


The Elite Features :
① LED indicator for liquid level status;
② Purely electronic circuit construction, non-mechanical operation, stable performance and long life;
③ High stability, high sensitivity, and excellent anti-interference performance, making it immune to external electromagnetic interference and suitable for use in complex environments;
④ Strong compatibility, penetrating various non-metallic containers such as plastic, glass, and ceramic, with a sensing distance of up to 10mm; suitable for detecting dielectric liquids such as water, alcohol, acids, and alkalis, as well as powdered small particles; and suitable for mounting on non-metallic containers such as plastic, glass, and ceramic, as well as on the exterior walls of containers or pipes. A variety of mounting brackets are available for diverse applications.
⑤ Open-circuit output, suitable for various control circuits, with a maximum output current of 300mA.
