Kistler Group Miniature Triaxial Accelerometer 8766A

Type 8766A... is an IEPE triaxial accelerometer designed for high temperature applications. Type 8766A... accelerometer uses Kistler’s PiezoStar shear element design which provides a wide operating frequency range and extremely low sensitivity to temperature changes, as shown in Figure 1 (see pg. 3). The IEPE sensor combines PiezoStar crystals and high gain integral hybrid microelectronics to achieve very low sensitivity variation over the operating temperature range, compared to other sensing element designs. The Kistler shear element technology also ensures high immunity to base strain errors. The accelerometer uses a welded titanium construction for low mass and an industry standard 4 pin connector, as well as a mini 4 pin connector for lower mass and wider frequency operation. An integral silicone cable variant is available for application of underwater vibration testing at up to 10 bars [150 psi]. All variations provide reliable measurements and long-term stability, especially at higher operating temperatures.
