The Columbia Models SR-107RFR and SR-207RFR are precision force balance angular accelerometers. This design makes use of the fluid rotor concept of sensing angular acceleration and in conjunction with the Columbia patented HP suspension system provides the ultimate in reliability and ruggedness under severe environmental conditions. These accelerometers provide excellent bias stability and rejection of linear acceleration inputs.

The SR-107RFR operates from +/-15VDC power, and the SR-207RFR is designed to operate from unregulated +24 to +32 VDC aircraft power. Both units provide a high level low impedance output and require no additional signal conditioning. Consult the factory for customized versions of these sensors.
