With a low dielectric requirement for target materials, and radar’s reliable accuracy in environments with foam or vapors, the easy to install True Echo™ PRX makes getting dependable level readings in hazardous places simple.

Explosion Proof
The True Echo™ PRX Explosion Proof Pulse Radar Level Transmitter brings the unassailable level readings of radar sensors to Class I, Division 1, and Class II/III, Division 1 hazardous locations.

Easy Wiring & Set-up
From a 2- or 3-wire 4-20 mA output, to pushbutton field calibration, everything about the True Echo™ PRX is easy.

Self Adjusting
True Echo™ PRX automatically adjusts signal power for optimal accuracy and output clarity.
