The Columbia Models SR-220RNP and SR-220RNC are precision force balance angular accelerometers designed for applications where space is at a premium. The Columbia patented HP suspension system provides extreme ruggedness and excellent rejection of linear acceleration. The two designs differ only in their electrical interface. The SR-220RNP provides solder pins and the SR-220RNC incorporates a 4-pin connector.

These accelerometers do not depend on fluid damping or rotational inertia but are 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. Consult the factory for customized versions of these sensors.
