North America-based company, Kistler has introduced the Type 8766A series of ultra-small PiezoStar accelerometers for tri-axial vibration and shock measurements.
The low-noise sensors are deployed for noise, vibration, harshness and structural evaluation in automotive, aerospace and basic testing purposes.
The Type 8766A exhibits novel measurement ranges of ±250 and ±500 g and features the company’s proprietary PiezoStar shear material crystal and intense-gain hybrid microelectronics. This has formed the basis to design a sensor that can function reliably across a broad frequency range, providing less thermal flexibility throughout its working thermal range and producing few base strain distortions.
The PiezoStar sensing materials are enclosed within a welded 0.43” or 10.9 mm, hermetically closed, titanium shielding that weighs less than 4.3 g. These are available as industry standard 4-pin, ¼-28 style connector for use in automotive applications or as an M4.5 tiny 4-pin connector for applications in space and commercial aviation.
The Type 8766A series features a ±50-g system that is protected in a hermetically shielded titanium enclosure weighing 16 g with a footprint of 0.65” or 16.5 mm. An intensive thermal model of the accelerometer can function at +329°F or +165° C and delivers additional TEDS potentiality for huge channel-level measurements.
