Type 8766A from Kistler North America is a family of lightweight, miniature triaxial PiezoStar accelerometers, offering simultaneous shock and vibration measurements in three orthogonal axes. The acclerometers offer enhanced thermal stability and performance within aerospace, automotive and general testing applications, claims the company.
With newly available ranges of ±250 and ±500g, the low-noise accelerometers incorporate the company's proprietary PiezoStar shear element crystal technology, together with high-gain internal hybrid microelectronics, to produce a sensor that can reliably operate over a dynamic frequency range and also offer low temperature sensitivity over its operating temperature range with low base strain errors, claims the company. The PiezoStar sensing elements of the accelometers are housed within a 0.43inch or 10.9mm welded, hermetically sealed, low-mass titanium housing weighing less than 4.3g, with a choice of an industry standard 4pin, ¼-28 style connector for automotive applications and a M4.5 mini four-pin connector for commercial aviation and space applications. For high-temperature applications, a version to +165°C is available, as well as optional TEDS capabilities for larger channel count measurements. The accelerometers also include a ±50g triaxial version, weighing 16g and occupying a 16.5mm footprint with hermetically sealed titanium housing. Several mounting accessories are available to provide ease of installation, especially for space constrained environments.
The accelerometers are suitable for high-temperature NVH and structural analysis applications, such as those found in laboratory/road test, powertrain testing and subsystems testing, as well as other applications where sensors are required to withstand extreme conditions while still maintaining accurate data readings. In addition, these sensors can be used anywhere from ground to air within aerospace applications with minimal sensitivity shift over the full operating temperature range.
