San Juan Capistrano, Calif. Endevco Corporation, a Meggitt group company, says it has introduced the industry's first miniature, 100 mV/g, high-temperature IEPE accelerometer for environments up to 175°C.
Designed for structural and component testing and monitoring in high-temperature environments, Model 67-100 features a welded titanium construction in a small cube 14.8 mm on each side. The triaxial model 67 is hermetically sealed against environmental contamination and provides high output sensitivity.
The Model 67 uses an Endevco Piezite Type P-8 crystal element operating in the annular shear mode to achieve low base strain sensitivity and excellent output stability over time, said Endevco. It also incorporates internal hybrid signal conditioners to achieve a low noise floor.
Other features include low-impedance output, 35,000 Hz resonant frequency, 5,000 g peak shock limit, and a 4-pin 10-32 side-mounted connector. The light weight device, less than 14 grams, is said to minimize mass loading effects.
Power to the Model 67, in the form of a constant current, travels through the same pins as the low impedance output signals. The device is designed for either adhesive mounting or screw mounting using an M4 screw.
A Model 67-10 with sensitivity of 10 mV/g and an operating temperature of 175°C is also available.
