OVERVIEW

The Sigma R.D.E. provides a field mounted terminal enclosure with an integral rechargeable desiccant cartridge. Although Sigma Controls’ level transmitters do not use “breather tubes” in the submersible cable, moist air can enter the transmitter if the end of the cable is terminated in a wet area or is submerged.

The R.D.E. combines a Nema 4X enclosure, two cable strain reliefs with a desiccant capsule that can be “recharged” in a convection or microwave oven hundreds of times. The clear viewing window permits the desiccant to be checked periodically.

Add an optional transient suppressor and the R.D.E. provides a convenient, safe field termination and transition point for the factory supplied heavy wall sensor cable to transition to standard ‘twisted pair’ cable.
