CS475, CS476 and CS477

Radar Water Level Sensors

Overview

The CS475, CS476, and CS477 are radar ranging sensors

typically used for water-level applications. They emit short

microwave pulses and then measure the elapsed time

between the emission and return of the pulses. The elapsed

time measurement is used to calculate the distance between

the sensor and the target (e.g., water, grain, slurry). The

distance value can then be used to determine depth.

The sensors differ in their measurement range and accuracy.

The CS475 can measure distances up to 20 metres with an

accuracy of ±5 mm; the CS476 can measure up to 30 metres

with an accuracy of ±3 mm; and the CS477 can measure up

to 70 metres with an accuracy of ±15 mm.

These radar sensors output a digital SDI-12 signal to indicate

distance and stage. This output is acceptable for recording

devices with SDI-12 capability including Campbell Scientific

dataloggers.
