Meggitt Sensing Systems’ Endevco model 7253D triaxial Isotron accelerometer is designed for applications requiring the measurement of shock and vibration simultaneously in three mutually perpendicular axes. Applications include testing of aircraft engines, industrial engines, missiles, aircraft/engine/weapons components, spacecraft components, flight testing, and industrial machinery. Available in sensitivities of 10 or 100 mV/g, the device is small and lightweight with a broad frequency response. Features include through-hole mounting for 360° cable orientation, hermetically sealed titanium housing to protect against environmental contamination, and signal ground isolated from the mounting surface by a hard anodized insulator. Dimensions are 0.70 × 0.70 × 0.375 in, with a weight of <10 g and operating temperature of -67°F to +257°F.
