 The Endevco Model 7253B is an extremely small, triaxial
piezoelectric accelerometer with integral electronics,
designed specifically for measuring vibration in three
orthogonal axes on mini-structures and small objects.
This accelerometer offers high resonance frequency and
wide bandwidth, its light weight (2.5 gm) practically
eliminates mass loading effects. A factory-replaceable
miniature cable assembly and an extension cable with 3
BNC output connectors are included.
Model 7253B features Endevco's Piezite® Type P-8 crystal
element, operating in annular shear mode, which exhibits
excellent output sensitivity stability over time. Each
axis of the accelerometer incorporates a low noise 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 isolated form the mounting surface.
Endevco Signal Conditioner Models 4416B, 133, 2792B, 2775A,
2793 or OASIS 2000 Computer-Controlled System are recommended
for use with this accelerometer.
Features:
• Triaxial, low profile
• Replaceable cable assembly
• Light weight (2.5 gm)
• Wide bandwidth, outstanding S/N
• Low-profile circuit board measurements, light weight
structural/modal studies
