Kistler Group Uniaxial Accelerometer 8211A

High temperature differential output acceleration sensor for measuring vibrations in a harsh environment. For applications in hazardous areas, the sensor is available with intrinsically safe Ex-ia and non-incendive Ex-nA certifications. Accelerometer Type 8211A... is designed for permanent vibration monitoring as well as for R&D application where size and weight have to be minimal. • Temperature range -55 ... 700 °C • Internally case isolated; differential charge output • Frequency response up to 5 kHz (±10 %) • Highest reliability • Not pyroelectric • Dimensions: 16.6 x 16.6 x 29.5 mm, Weight: 30 gramm • ATEX / IECEX certified Description Core of the sensor is the single crystal PiezoStar measuring element, which has a temperature capability of over 700 °C and without any pyroelectric effect. The sensor features a shear design, which significantly reduces the influence of temperature and base strain. Other features are high frequency response, a hermetic construction of the housing and a small design. The sensitive axis of the sensor lies in the Z - direction. To reach highest resolution in harsh environment, the sensor provides a differential signal output and features an internally case isolated design. The integrated hardline cable is robust, low noise and has a temperature rating of over 700 °C. The cable is available in a standard length of 3 m as well as in customer specific lengths. The accelerometer is available in an ATEX / IECEx certified version for applications in hazardous areas.
