| Endevco 2272 Piezoelectric Accelerometer
Endevco's
new Model 2272 is a piezoelectric accelerometer designed specifically to
measure vibration at temperature extremes. A self-generating unit that
requires no external power source for operation, the unit is hermetically
sealed for use in harsh environments and exhibits excellent output
sensitivity stability over time. Its unique sensing elements offer an
unusually flat temperature response over a temperature range from -269°C
(-452°F) to 260°C (500°F). Low temperature applications include
cryogenic equipment and processes, and the accelerometer can also be used
for high-temperature vibration measurements in aerospace, automotive and
industrial testing applications.
The
Model 2272 features Endevco's PIEZITEТ Type P-10 crystal element,
operating in compression mode. Signal ground is connected to the outer
case of the unit. When used with an isolated mounting stud, the
accelerometer is electrically isolated from ground. A 10-32 UNF-2A side
connector mates with a low-noise coaxial cable that is supplied for
error-free operation.
Endevco
Models 133 or 2775A signal conditioners or OASIS 2000 Computer-Controlled
System are recommended for use with this high-impedance accelerometer. |
