The Kistler Group has announced the global market launch of Kistler Type 8766A(x), a triax- ial PiezoStar accelerometer in a very small cube with 3,7 g mass, designed for accurate measurement of frequency events from 0,5 ... 10 000 Hz. The extremely low thermal sensi- tivity shift of –0,005 %/K allows use under changing temperature regime with high preci- sion. The extremely stiff PiezoStar crystal sensing element provides a flat frequency response with no slope over the entire usable frequency range in contrast to soft piezoelectrics, which improves acceleration level measurement tremendously. It is one of the only accelerometers with 3 different mounting thread holes in each axis for flexible mounting capability and frequency response calibration without any adapter in a tight back-to-back calibration.

Available now in 250 and 500 g range, the Kistler Type 8766A... incorporates a shear loaded piezoelectric PiezoStar crystal sensing element, with internal Piezotron® charge con- verter matching most current front end systems with constant current line drive capability.

Kistler Type 8766A(x)By offers a standard temperature range form –54 ... 120 °C with Type 8766A(x)Ty offering extended temperature range up to 165 °C. Two different connector versions are offered to improve mass loading effects by the smaller lightweight 4 pin M4,5 connector in contradiction to the 4 pin 1½2-28 one. The case has three 5-40UNF threaded holes for stud mounting in all three perpendicular dimensions. The titanium housing is her- metically sealed and can be exposed to extreme environmental conditions.

With its extreme wide and flat frequency response this unique accelerometer was designed for the use in modal and durability testing under elevated temperatures for automotive, aerospace and space structures and also for crash induced sound sensing of automotive impact testing. Various breakout cables and insulated mounting studs are available.
