SAN JUAN CAPISTRANO, Calif, 23 June 2011. Meggitt Sensing Systems in San Juan Capistrano, Calif., is introducing the Endevco model 25A small ISOTRON (IEPE-type) piezoelectric accelerometer for use in high-reliability vibration measurement on small structures and objects. Applications include measuring overall vibration levels of scaled models and smaller electronic components in aerospace, automotive, electronic products, and in-laboratory testing.


The Endevco model 25A piezoelectric accelerometer vibration sensor weighs 0.2 grams, and helps systems designers reduce unwanted mass loading effects. The device's electronics that convert high-impedance input into a low-impedance voltage output through the same cable that supplies the required 4 milliamps constant current power.

The device also isolates its signal ground from its mounting surface with a hard anodized surface. The unit comes with two pre-installed, field-reparable fine-gage (34 AWG) wire output leads. An assembly lead may be reinstalled at the factory if necessary for the application.

An optional triaxial mounting block (model 2950M16) is available for three-axis vibration measurement. The devices are adhesive mounted with the model 31275 field removal tool.

Options include the model 133 three-channel piezoelectric signal conditioner; the model 4416B low-noise, compact signal conditioner; the model 2775B PE, Isotron and RCC signal conditioner; the model 6634C vibration amplifier; the model 4999 multi-channel signal conditioner; or the Oasis 2000 (4990A-X with cards 428 and/or 433) computer controlled system.
