Introduction:
<1>. QDY30A submersible Water Level Sensor, its 304 &316 stainless steel and hermetically sealed housing make it suitable for most industrial liquids and oils.
<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. The conductors of the cable are also isolated from the outside environment to keep the level sensor operational for long-term use.
