Description

The Endevco® model 2221F piezoelectric accelerometer is designed specifically for high temperature vibration measurement on small structures and objects. The unit is hermetically sealed and is ideal for use in extreme environmental conditions. Its light weight (11 gm) effectively minimizes mass loading. The accelerometer is a self-generating device that requires no external power source for operation. The model 2221F features Endevco’s Piezite® type P-8 crystal element operating in annular shear mode. This unit exhibits excellent output sensitivity stability over time. Signal ground is connected to the outer case of the unit and, when used with an isolated mounting screw, the accelerometer is electrically isolated from ground. A low-noise coaxial cable is supplied for error-free operation. The transducer has a centrally located thru bolt, allowing for 360° cable orientation. The unit may also be adhesively mounted if the application permits. Key features ■ High temperature operation (+260°C) ■ Hermetically sealed ■ 360° cable orientation ■ Lightweight ■ Aerospace and flight testing
