1-axis accelerometer 2220E

piezoelectrichigh-temperatureminiature

3 pC/g, -67°F to +500°F, isolated, thru-hole mount, 3.1 grams Description The Endevco® model 2220E is a miniature piezoelectric accelerometer designed specifically for high temperature vibration measurement on mini-structures and small objects. The unit is hermetically sealed and ideal for use in extreme environments. Its light weight (3.1 gm) effectively eliminates mass loading. The accelerometer is a self-generating device that requires no external power source for operation. Model 2220E features Endevco’s Piezite® type P-8 crystal element operating in annular shear mode. This configuration exhibits excellent output sensitivity stability over time. Signal ground is connected to the outer case of the unit. When used with the supplied isolated mounting screw assembly, the accelerometer is electrically isolated from ground. A specially designed, low-noise coaxial cable is supplied for error-free operation. The transducer utilizes a centrally located thru bolt, allowing 360° cable orientation. The unit may also be mounted with an adhesive.
