  • UL listed
  • Flush clog-free sensor; 316L SST
  • Enhanced internal surge and lightning protection
  • 2.5 inch sensing diaphragm
  • Vented cable for automatic barometric compensation
  • Double-sealed submersible cable exit
  • Corrosion resistant

The lift station transmitter system consists of a submersible pressure sensing element cased in a 316L SST housing. The sensor's electronics are capable of withstanding lightning strikes and meet RCTA/DO 160D for lightning direct effects and surge protection for FAA and MIL-STD test and NASA standard electrical surge requirements. All Sewage Lift Station Wastewater Level Sensors are corrosion resistant and clog free.

The WL430 Sewage Lift Station Wastewater Level Sensor is supplied with 40 ft. of standard polyurethane shielded and vented cable. The unique cable venting system allows for barometric pressure differential compensation while keeping the elements out, using a Gortex filter encapsulated tip. The "Steelcage" design gives full protection and allows sensing to sewage levels no matter how much debris/mud/sand or rags build up.
