Model 7251HT High Temperature Miniature ISOTRON
Piezoelectric Accelerometer designed specifically for
measuring vibration on most structures.
Endevco's new Model 7251HT-10 and -100 is a miniature piezoelectric
accelerometer with integral electronics that measures vibration on
most structures at temperatures continuously up to 150°C (302°F).
The low-profile unit is hermetically sealed against environmental
contamination, and offers high output sensitivity and wide bandwidth.
Dynamic range is ±500 g's for the -10 model and ±50 g's for the -100
model, while voltage output sensitivity is 10 mV/g for the -10 model
and 100 mV/g for the -100 model. This new lightweight (14 gm) design
effectively minimizes mass loading effects and is ideal for general-purpose
and aerospace applications.
The Model 7251HT 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. An internal hybrid signal conditioner
incorporated in a two-wire system transmits its low-impedance voltage
output through the same cable that supplies the constant-current power.
Signal ground is connected to the accelerometer's outer case, and when
the unit is used with the supplied isolated mounting screw, is electrically
isolated from ground. The centrally located mounting bolt permits 360°
cable orientation, a very desirable feature for many applications.
Endevco's Signal Conditioner Models 133, 2792B, 4416B, 2793, 2775A
or OASIS Computer-Controlled System are recommended for use with
the Model 7251HT accelerometer.
