SSR100 Stage Sensor Recorder


This integrated system was retired because it contained a CR510 datalogger. The SSR100 monitored and recorded water level. It consisted of a datalogger, shaft encoder, quadrature decoder, data display unit, and environmental enclosure. The system was pre-programmed to measure the shaft encoder, a user-supplied tipping bucket rain gage, and a user-supplied SDI-12 sensor. A GOES satellite transmitter could be added to the system. Earlier SSR100 systems used the SAT HDR GOES transmitter. The TX312 replaced the SAT HDR GOES transmitter when the SAT HDR GOES transmitter was retired.

Detailed Description

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).
