Columbia Models SA-522PE and SA-522SE miniature force balance accelerometers are lightweight sensors designed to operate from a wide range of acceptable power variations with low current draw. These devices are ideal for battery-powered applications.

The sensors are designed with an output configuration comparable to strain gage accelerometers, but the superior force balance technology of Models SA-522PE/SE provides a higher level output as well as superior performance, ruggedness, and reliability when compared to strain gage technologies. Models SA-522PE and SA-522SE Accelerometers are identical except for their respective electrical interface. Consult the factory for customized versions of these sensors.

Exports of accelerometers from the United States are subject to the licensing requirements of the Export Administration Regulations (EAR) and/or the International Traffic in Arms Regulations (ITAR).
