Piezoelectric
Accelerometer Endevco Model 7201-10-50-100
The Endevco Model 7201 is a stud mounted, ISOSHEAR piezoelectric
accelerometer designed for general vibration measurement
on structures and objects. The ISOSHEAR design is extremely
stable and virtually insensitive to such environmental
inputs as base bending and thermal transients. The unit
is hermetically sealed against external contamination.
The accelerometer is a self-generating device that requires
no external power source for operation.
The Model 7201 features Endevco's Piezite® Type P-8
crystal element, operating in shear mode, which exhibits
low base strain sensitivity, high resonance frequency
and excellent output stability over time. Signal ground
is connected to outer case of the unit. When used with
an isolated mounting stud, the accelerometer is electrically
isolated from connector. A low-noise coaxial cable is
supplied for error-free operation. A model number suffix
indicates acceleration sensitivity in mV/g; i.e., 7201-50
features output sensitivity of 50 pC/g.
Endevco Signal Conditioner Models 133, 2775A or CCAS™
are recommended for use with this high impedance accelerometer.
Features:
• Requires no external power
• ISOSHEAR®
• To +500°F (+260°C)
• Flat to 12 kHz (7201-10)
• Hermetically sealed
• General purpose
