The COLUMBIA Model SR-220RNP and SR-220RNC are miniature force balance angular accelerometers designed for applications where space is at a premium. The COLUMBIA HP suspension system provides extreme ruggedness and excellent rejection of linear acceleration. These sensors do not depend on fluid for damping or rotational inertia but is electrically damped. This results in exceptional high frequency characteristics for an angular accelerometer in its range of sensitivity. The servo loop design guarantees exceptional thermal stability of zero bias, scale factor and frequency characteristics. Specifications: SR-220RNP Operational: Ranges Available - ±100, ±500, ±1000, ±5000 Rad/Sec2 Output Voltage - ±5 VDC into 100 K Load Output Impedance – Less Than 5000 Ohms Excitation - ±15 VDC Less than 20 mA Accuracy - ±0.25% F.R.
