SSR100

Stage Sensor/Recorder


The SSR100 is an integrated system that monitors and records water level. It consists of a shaft encoder and a Campbell Scientific datalogger housed in an environmental enclosure. The system is pre-programmed to measure the shaft encoder, a tipping bucket rain gage, and an SDI-12 sensor. An alphanumeric LCD inside the enclosure displays the real-time measurements. A High Data Rate GOES satellite transmitter can be added to the system to transmit measurements via Geostationary Operational Environmental Satellites (GOES).
