WL400 Level Sensor (Submersible Pressure Transducer) Cable Length:300 ft All components use a 5/8"The Global Water WL400 Level Sensor is a rugged, submersible pressure transducer engineered for highly accurate water level measurement across a wide range of demanding environments. Each sensor uses a solid state transducer with a flexible silicon wet wet diaphragm, encapsulated in a 304L stainless steel housing (approx. 13 16" diameter) and finished with marine grade epoxy so moisture can never work its way in and cause drift.
