CS477-L Radar Water-Level Sensor, 230 ft Maximum Distance
Services Available
Repair Yes
Calibration No
Free Support Yes

Overview

The CS477 is a radar-ranging sensor that monitors water level of rivers, lakes, tidal seas, and reservoirs. It can measure distances up to 70 meters. The CS477 outputs a digital SDI-12 signal to indicate distance and stage. This output can be read by many of our dataloggers.

Benefits and Features

  • FCC approved for outdoor use (FCC ID number MOIPULS616263)
  • Ideal for areas where submersed sensors can be damaged due to corrosion, contamination, flood-related debris, lightning, or vandalism
  • Compatible with most Campbell Scientific data loggers
  • Low maintenance—no moving parts significantly reduces maintenance cost and time
  • Low power consumption
  • Rugged enough for harsh environments—NEMA rated 4X
  • Wide operating temperature range (-40° to +80°C)

Detailed Description

The CS477 emits short microwave pulses and then measures 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.
