Accelerometer measures vibration on structures.
April 15, 2002 - Ultra miniature ceramic shear accelerometer type 8778A500 offers 10 mV/g vibration measurement sensitivity, 0 to 500 g measuring range, and a ±5% frequency response of 2 to 9000 Hz. Unit minimizes changes in dynamic response due to accelerometer mass loading. Construction includes titanium housing and hard anodized aluminum base, which provides ground isolation. Piezo-ceramic sensing element provides immunity to base bending and thermal influences.

New Ultra Light Weight Accelerometer For Vibration Measurements On Small Structures
Kistler Instrument is pleased to announce the release of a new ultra miniature ceramic shear accelerometer type 8778A500 for general vibration measurements on small, light weight structures. Weighing only 0.29 gram, the physical size is much smaller than the 10-32 electrical connector that terminates the end of integral coaxial cable used to conduct power and signal.
The 8778 accelerometer features a high vibration measurement sensitivity of 10 mV/g with a measuring range of 0 to 500g and a ± 5% frequency response of 2 to 9000 Hz. Changes in dynamic response due to accelerometer mass loading is minimized when using the unit. The unit's construction is a combination titanium housing and hard anodized aluminum base which provides ground isolation. The piezo-ceramic sensing element oriented in a shear mode configuration provides immunity to base bending and thermal influences.
The 877A500 accelerometer contains a built-in charge amplifier that provides a low impedance voltage output, allowing the use of standard low cost cabling. This voltage mode sensor, is CE compliant and can be powered by a wide variety of Kistler Piezotron(R) Coupler/Signal Conditioners or from any industry standard IEPE power source.
Typical applications include PC Board stress screening, critical component evaluation on disk drive assemblies.
Kistler is a worldwide supplier of precision instrumentation for the measurement of, pressure, force and acceleration serving the R&D, Industrial and OEM Communities.
