The Endevco® Model 35A is an extremely small, adhesivemounted piezoelectric accelerometer with integral electronics, designed specifically for measuring vibration in three orthogonal axes on very small objects. The unit weighs only 1.1 gm, reducing unwanted mass-loading effects. The unit comes with 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 4-conductor cable is attached to the ends of these leadwires, which is terminated with three BNC connectors. The Model 35A is ideal for measuring vibration in scaled models, small electronic components, and biomedical research.
