Meggitt Sensing Systems Introduces Endevco ISOTRON Piezoelectric Accelerometer

By DE Editors

Meggitt Sensing Systems has introduced the Endevco model 25A, an ISOTRON (IEPE-type) piezoelectric accelerometer, designed to support high-reliability vibration measurement requirements on small structures and objects. With a total weight of just 0.2 gram, its design helps reduce unwanted mass loading effects.

Featuring a shear mode construction, the Endevco model 25A incorporates integral electronics that convert high-impedance input into a low-impedance voltage output through the same cable that supplies the required 4 mA constant current power. Signal ground is isolated from the unit’s mounting surface by a hard anodized surface. The unit comes with two pre-installed, fine gage (34 AWG) wire output leads, allowing for immediate field use. If required, a new assembly lead may also be reinstalled at the factory. A heavier gage (28 AWG) cable is also provided for extension purposes. In addition, an optional triaxial mounting block (model 2950M16) is available to facilitate three-axis vibration measurement requirements. Units are adhesive mounted with a special field removal tool (model 31275) supplied for convenience.
