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. campbellsci.eu/cs475_476_477 More info: +44(0) 1509 828 888 Non-Contact Water Level Monitoring Meets EU LPR Standard EN302729-1/2 Campbell Park, Shepshed, LE12 9GX UK | +(0)1509 828888 | sales@campbellsci.co.uk | wwwcampbellsci.eu UK | AUSTRALIA | BRAZIL | CANADA | COSTA RICA | ENGLAND | FRANCE | GERMANY | SOUTH AFRICA | SPAIN | Benefits and Features Ideal for areas where submersed sensors can be damaged due to corrosion, contamination, flood-related debris, lightning or vandalism Low maintenance - no moving parts significantly reduces maintenance cost and time Compatible with our CR200X-series, CR510, CR10X, CR800- series, CR1000, CR3000 and CR5000 dataloggers Low power consumption Rugged enough for harsh environments - NEMA rated 4X Wide operating temperature range (-40° to +80°C) Individual FCC licence not required FCC compliant (FCC IC# MOIPULS 616263) A cut away view of the optional field enclosure showing sensor placement.

CS476 - Radar Water Level Sensor with 30 m Maximum Depth. CS477 - Radar Water Level Sensor with 70 m Maximum Depth. Enclosure Options Field enclosure that houses a CS476 or CS477 head. Typically the #27162 Enclosure Mounting Kit is also ordered (see Accessories). Accessories #25619 - Bubble level that helps align the radar sensor in a vertical position, which prevents measurement errors. #25616 - Adjustment/Display Module used for changing settings, testing, and diagnostics. A cap is available for this display (see below). #25654 - Cap with window for use with the #25616 display. #27162 - CS476 and CS477 Enclosure Mounting Kit. Top view of the optional field enclosure showing the sensor placement and backplate for mounting a datalogger. Flat edges must be parallel with each other, and face this direction.
