Meggitt Accelerometer Series operates to 108 Rad and +550°F (+288°C)

Meggitt Sensing Systems has introduced the Endevco model 7703A series, a high-temperature radiation tested piezoelectric accelerometer family, designed for general vibration measurements on structures and objects, particularly within nuclear environments.

Available in ranges of 50, 100, 200, 300 and 1000 pC/g, the model 7703A series features a 10-32 side connector. The accelerometers have been tested in a radiation environment of up to a 108 Rad Integrated Gamma Flux radiation rating (Integrated Neutron Flux of up to 1010 N/cm2) and are temperature compensated to +288°C (+550°F). They are ground isolated to prevent EMI/ground loop interference and are hermetically sealed to avoid external contamination. As a piezoelectric sensor, the accelerometer is a self-generating device requiring no external power for operation.
