Endevco® model 25A Isomin™ is an extremely small, adhesive mounted piezoelectric accelerometer with integral electronics, designed for measuring vibration on very small objects. The unit weighs only 0.2 gm, reducing unwanted mass loading effects. The unit comes with two pre-installed fine gage (34 AWG) wires as output leads.

These leads can be easily repaired in the field, or a new lead assembly may be reinstalled at the factory. A heavier gage (28 AWG) cable is also provided for extension purpose. The model 25A is ideal for measuring vibration in scaled models, small electronic components, and biomedical research. An optional triaxial mounting block (model 2950M16) is available.

Model 25A features Endevco's Piezite® Type sensing element operating in shear mode. The internal electronics inside the accelerometer converts high impedance input into low impedance voltage output through the same cable that supplies required 4 mA constant current power. Signal ground is isolated from the mounting surface of the unit by a hard anodized surface. A tool is included for proper removal in the field. Endevco® signal conditioning models 133, 4416B, 2792B, 2793, 2775A are recommended for use with this accelerometer.
