Meggitt Sensing Systems recently launched the Endevco model 7253D triaxial Isotron accelerometer. The company's latest offering is designed for applications requiring the measurement of shock and vibration simultaneously in three mutually perpendicular axes. Primary applications for the Endevco model 7253D include the testing of aircraft engines, industrial engines, missiles, aircraft/engine/weapons components, spacecraft components, flight testing and industrial machinery.

Available in sensitivities of 10mV/g or 100 mV/g, the Endevco model 7253D is small and lightweight with a broad frequency response. Features include thru-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 low-profile at 17.78x17.78x9.525mm, with a weight of Each axis utilises an Endevco type P-8 shear piezoelectric sensing element in conjunction with a hybrid charge amplifier to provide a low-impedance output of 5V full scale in a two-wire IEPE system configuration. A constant current excitation of 2 to 20mA is required for each axis, with the electrical connection made to each axis through a 4-pin connector.

Accessories included with the Endevco model 7253D include the 3027AM3-120 cable, 42883 mounting screw assembly and EHM488 wrench. Optional accessories include the models 123, 133, 2775B or 2793 signal conditioner.
