 The Endevco Model 7254A is a small and rugged piezoelectric
accelerometer with integral electronics, designed specifically
for measuring vibration on structures and objects. The
unit is hermetically sealed against environmental contamination,
features high output sensitivity, high signal-to-noise
ratio, and wide bandwidth. It offers outstanding value
at a very reasonable price.
The Model 7254A features Endevco's Piezite® Type P-8
crystal element, operating in annular shear mode, which
exhibits low base strain sensitivity and excellent output
stability over time. This accelerometer incorporates an
internal hybrid signal conditioner in a two-wire system,
which transmits its low impedance voltage output through
the same cable that supplies the constant current power.
Signal ground is connected to the outer case of the unit.
When used with an isolated mounting stud, it can be electrically
isolated form ground. A model number suffix indicates
acceleration sensitivity in mV/g; i.e., 7254A-100 features
output sensitivity of 100 mV/g.
Endevco Signal Conditioner Models 133, 2792B, 2793, 2775A,
2776 or 4416B are recommended for use with this accelerometer.
Features:
• Outstanding dynamic range
• Wide bandwidth, annular shear
• Hermetically sealed, rugged
• Best value in accelerometers
• General purpose vibration measurements
