Description
The accelerometer Type 8704B5000 accurately measures mechanical shock or vibration up to 5 000 g. The unique K-Shear
sensing system is insensitive to base strain, transverse acceleration and thermal transients. Quartz shear cut, sensing crystals
ensure long-term stability not achievable with other sensing
materials.

The built-in Piezotron® electronic impedance converter, provides a high signal level at a low impedance output allowing
the use of inexpensive coaxial cable. The accelerometer can
be powered by a Kistler 5100 series coupler/signal conditioner
or by any industry standard IEPE (Integrated Electronic PiezoElectric) sensor power source.
Verticle
Mounting
A threaded 10-32 UNF stud provides positive attachment of
the accelerometer to the test structure. Reliable and accurate
measurements require that the mounting surface be clean
and flat. The operating instruction manual for the accelerometer Type 8704B5000 provides detailed information regardDiminsional Text
Measurements
ing mounting surface preparation.
The sensor is constructed in a hermetically sealed, welded, ti- 0.55
tanium case. The 10-32 thread top connector features a robust
design to provide years of reliable operation under conditions
where repeated shock and vibration is encountered.
Horizontal
Application
The Type 8704B500 can be used for general purpose vibration
measurements in a laboratory or for environmental product
shock testing in vehicle, automotive, metal-to-metal impacting, shipping package design and survivability.
