 The Endevco Model 7251AHT is a small piezoelectric accelerometer
with integral electronics, designed specifically for measuring
vibration up to +302°F (+150°C). The unit is hermetically
sealed against environmental contamination, offers high
output sensitivity, and wide bandwidth. This new light
weight (10.5 gm) design effectively minimizes mass loading
effects.
The Model 7251A 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 the 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 outer case of the unit and,
when used with the supplied isolated mounting screw, it
is electrically isolated from ground. The centrally located
mounting bolt permits 360° cable orientation, a very desirable
feature in many applications. A model number suffix indicates
sensitivity in mV/g; i.e., 7251AHT-10 features output
sensitivity of 10 mV/g.
Endevco Signal Conditioner Models 133, 2792B, 2793, 2775A
or CCAS™ are recommended for use with this accelerometer.
