Model 2221F offers unique thru-bolt (thru-hole) mounting capabilities, which allow for 360° cable orientation, and reliable operation in temperatures of up to +500°F (+260°C), in frequencies of up to 10,000 Hz. The sensor features Endevco’s Piezite® -type P-8 crystal element, operating in annular shear, and exhibiting 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. Units are housed in a rugged, stainless steel, hermetically sealed case, making them ideal for use in extreme environmental conditions.
The sensor’s lightweight (11 gm) construction effectively minimizes mass loading, allowing it to be successfully used in the testing of small structures and objects. Model 2221F is also a self-generating device, with no external power requirements. Adhesive mounting is also available as the application permits. A low-noise coaxial cable is supplied for error-free operation.
