True Echo Dual Frequency Pulse Radar Level Transmitter For Solids
Dependable Level Readings From Difficult Materials
Whether powders or pellets, grains or granules, the True Echo™ PRS’s dual frequencies bring the unassailably accurate level readings of radar sensors to difficult to measure solids.
Description
Whether powders or pellets, grains or granules, the True Echo™ PRS’s dual frequencies bring the unassailably accurate level readings of radar sensors to difficult to measure solids.
Dual Frequency
Dual frequencies means higher degree of accuracy and precision in measuring accumulating solids.
Easy Wiring & Set-up
From an isolated 4-20 mA output, to pushbutton field calibration, everything about the True Echo™ PRS is easy.
Self Adjusting
True Echo™ PRS automatically adjusts signal power for optimal accuracy and output clarity.
