New Endevco piezoelectric accelerometer series from Meggitt Sensing Systems operates to 108 Rad and +550°F (+288°C)

Meggitt Sensing Systems, a Meggitt group division, 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 and highly stable shear mode construction, offering low base strain sensitivity, high resonance frequency, insensitivity to thermal transients and excellent output stability over time. The accelerometers have been tested in a radiation environment of up to 108 Rad 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. A 10-foot high-temperature cable assembly and 10-32 mounting stud are supplied for easy installation and error-free operation.

Both 50 and 100 pC/g series ranges are well-suited for nuclear environments because of their high sensitivity and 108 Rad Integrated Gamma Flux radiation rating (Integrated Neutron Flux of up to 1010 N/cm2), with triaxial mounting capabilities for vibration measurements across three orthogonal axes (via optional triaxial mounting block model 2950A). The 1000 pC/g version is ideal for high-sensitivity, high-output applications where vibration inputs are low. Additional applications include modal measurements on larger structures and objects, engine testing, oil and gas pipeline monitoring, nuclear power plant pipeline and valve vibration monitoring, aerospace metallurgy and automotive metrology.

Recommended optional accessories include the model 133 three-channel piezoelectric signal conditioner; the model 2771C in-line charge converter; the model 2775B signal conditioner; the model 6634C vibration amplifier; or the model 4990A-X Oasis 2000 computer-controlled system. All Endevco® accelerometers are accompanied by a comprehensive five-year product warranty. In addition, the series 50, 100 and 1000 pC/g ranges are available at specially discounted pricing as part of the –R replacement sensors program.
