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.
