♦Measuring principle: submersible level sensors provide continuous liquid level measurement by sensing the hydrostatic pressure produced by the height of liquid above the sensor.
♦The QDY30A has a 28mm diameter (can be customize 19mm diameter) 304/316 stainless steel protective housing and a nose cap for protection of the sensor diaphragm.The shielded cable with atmospheric vent tube, and providing a 4-20 mA and others output signal such as RS485, 0-5V. The IP68 waterproof means it can be used in water for a long time.
♦(1)QDY30A submersible Water Level Sensor, its 304 &316 stainless steel and hermetically sealed housing make it suitable for most industrial liquids .
♦(2)The welded housing is tested in-house via a helium leak tester to ensure proper protection. Ventilation tube in the cable automatically compensates for changes in atmospheric pressure above the tank.
♦(3)The conductors of the cable are also isolated from the outside environment to keep the level sensor operational for long-term use.
