Hermetically sealed piezoelectric accelerometer with integrated electronics
10 / 100 mV/g, 7.8 g | Model 751 Meggitt Sensing Systems - Measurement Group

The Endevco® model 751 is a low-cost, lightweight piezoelectric accelerometers with integral electronics, designed specifically for measuring vibration on small structures. This unit is hermetically sealed against environmental contamination. The 751 features a high output sensitivity, high signal-to-noise ratio, and a wide bandwidth. Model 751 is the best value in accelerometers on the market today.

The model 751 features Endevco's Piezite® Type P-8 crystal element, operating in annular shear mode, which exhibits low base strain sensitivity and excellent output stability over time. This accelerometer incorporates an internal hybrid signal conditioner in a two-wire system, which transmits its low impedance voltage output through the same cable that supplies the constant current power. Signal ground is connected to the outer case of the unit. When used with an isolated mounting stud, it can be electrically isolated from ground. A model number suffix indicates acceleration sensitivity in mV/g; i.e., 751-100 features output sensitivity of 100 mV/g.
