Mac transmitter Submersible Analog Water Level Sensor for irigation system agriculture


Product Description


L703 is a submersible Water Level Sensor suitable for liquid level and depth measurement. It consists of a piezoresistive sensing element encased in a 316 SS housing. Its all stainless steel, hermetically sealed housing make it suitable for immersion in most industrial liquids and oils. The welded housing is tested in-house via a helium leak tester to ensure proper protection. The conductors of the cable are also isolated from the outside environment to keep the level sensor operational for long-term use. Each submersible pressure transducer features a removable nose cone at the sensor which protects the diaphragm from damage.



A vented cable provides an atmospheric pressure reference. Ventilation tube in the cable automatically compensates for changes in atmospheric pressure above the tank. The vent is protected with a maintenance free filter eliminating particulate or water droplets from entering the transducer.
