Miniature triaxial accelerometers operate over wide temperature range
18 June 2010
Type 8766A miniature triaxial accelerometers from Kistler Instruments are available in versions that operate over the temperature range of -54 Deg C to +165 Deg C, and with integrated high-gain microelectronics to ensure precision and long-term reliability in harsh operating conditions.
The three models in the range, ±50g, ±250g and ±500g, use the Kistler PiezoStar shear element design which 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 quartz and ceramic sensing element designs. The hermitically sealed, welded titanium, ground isolated, IP68 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 via a central hole tapped 6-32 UNC on each of three sides of the cube design gives maximum mounting flexibility and allows the miniature 4-pin ceramic connector to be positioned throughout 360 Deg 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 integrated electronic piezoelectric compatible power source.
