Technical Data
Description
The PR3441 submersible transmitter has been
designed for the accurate measurement of thedepth and level of liquids in many applications.
Standard output signal is 4-20 mA two wire with supply range
13-36 Vdc. Electrical connection is via a high strength moulded
polyurethane cable with integral tube for excellent troublefree venting to the surface atmosphere. The standard depth

inlet holes to prevent sludge build-up. The PR3441 transmitteris suitable for depth and level measurement in boreholes 25mm diameter or greater. Lightening Protection is available onrequest.

Applications include borehole level and reservoir levelmonitoring, water mains pressure measurement in inspectionchambers, power level and outlet pressure measurement onsubmersible pumps.
