Kistler Instruments' Type 8766A miniature triaxial accelerometers are available in high-temperature versions with an operating temperature range of -54 to +165degC and integrated high-gain microelectronics to ensure precision and long-term reliability in harsh operating conditions. Typical applications include industrial quality control, automotive engine bay and under-vehicle measurements, aerospace subsystem vibration testing, and other applications where high temperatures may be encountered.
The three models in the range for measuring +/-50, +/-250 and +/-500 'g' use the Kistler PiezoStar shear element design that provides a wide operating frequency range and outstanding long-term precision and stability. The sensor design combines PiezoStar crystals and integral hybrid microelectronics to achieve very low sensitivity variation over the wide operating temperature range compared with designs using quartz or ceramic sensing elements. The hermetically sealed, welded titanium, ground isolated, IP68-sealed housing permits operation in harsh, dirty or wet environments, and a TEDS (Transducer Electronics Data Sheet) option is available to simplify installation and set-up.
Mounting by means of a central hole tapped 6-32 UNC on each of three sides of the cube design gives good versatility and enables the miniature four-pin ceramic connector to be positioned at any angle for convenient cable orientation. Alternatively, wax mounting may be used where stud mounting is not possible. The Type 8766A triaxial accelerometers can be powered by any Kistler power supply coupler or industry-standard IEPE (Integrated Electronic Piezoelectric) compatible power source.
