About the APR3442 Slim Submersible Depth & Level Pressure Transducer

The APR3442 ultra slim submersible transmitter has been designed for the accurate measurement of the depth and level of liquids in borehole applications.

Standard output signal is 4-20 mA two wire. Supply range 13-36 Vdc, with integral transient voltage protection. Electrical connection is via a high strength molded polyurethane cable with internal tube for excellent trouble-free venting to the surface atmosphere. The standard depth transmitter is fitted with a stainless steel nose cone with radial inlet holes to prevent sludge build-up. The APR3442 has a slim-line 16 mm diameter suitable for 19 mm boreholes or greater.
