High Temperature Acceleration Sensor ≥700°C Kistler 8211A

• High temperature differential output acceleration sensor for measuring vibrations in a harsh environment up to 480°C. For applications in hazardous areas, the sensor is available with intrinsically safe Ex-ia and non-incendive Ex-nA certifications.

Description

• Core of the sensor is the single crystal PiezoStar measuring element, which has a temperature capability of over 480 °C and is not pyroelectric. The sensor features a shear design, which significantly reduces the influence of temperature and base strain.Other features are high frequency response and a hermetic construction of the housing and a compact design. The sensor 8211A… is available with two different footprints. A compact and rugged standard ARINC triangular footprint and a square footprint with 25×25 hole pattern. 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 ATEX / IECEx certified for applications in hazardous areas.

Application

• Main applications are condition monitoring of gas turbines, structural analysis of turbomachinery and general purpose high temperature applications, which require:
  • Temperature capability up to 700 °C
  • Ex-certification for use in potentially explosive environment
  • Integrated hardline cable
  • EMI immune measuring chain
