Enduring temperatures of up to 1000 degrees Celsius is not a problem for the new sensor or cable
Measuring vibrations at up to 1000 degrees Celsius
A new single axis accelerometer for vibration monitoring from Kistler delivers reliable results at temperatures up to 700 degrees Celsius over the long term and up to 1000 degrees for short periods of time. The 8211A sensor is certified to ATEX and IECEX for use in explosion protection making it suitable not only for monitoring purposes, but also for use under extreme conditions in a wide variety of applications.
Measuring vibrations inside the combustion chambers of gas turbines, rocket or aircraft engines ambient temperatures are often in the high three-digit range. Under extreme conditions, these measurements must provide exact data as the basis for further developments, for example on instabilities in the combustion process. However, only a few sensors are able to withstand the extreme heat and temperature fluctuations and still deliver reliable measurement data. The new 8211A sensor from Kistler has been designed specifically for such conditions in order to measure vibrations in various extreme industrial environments.
Maximum accuracy even at extreme temperatures
The sensor owes its heat resistance primarily to the PiezoStar crystal at the heart of the accelerometer, which is especially suitable for these applications. Kistler grow the artificial crystal in its own laboratories to eliminate quality fluctuations and supply bottlenecks which are common with natural materials such as tourmaline. Kistler's artificial crystal is produced to a consistent quality standard and is not subject to variable availability. The robust hardline cable used with the sensor is insulated with magnesium oxide and is equally resistant to heat:
Enduring temperatures of up to 1000 degrees Celsius is not a problem for the new accelerometer or cable from Kistler.
The 8211A sensor is suitable for many applications with extremely high ambient temperatures, such as testing rocket engines.
Differential measurement chain ensures reliable results
The core technology of the 8211A accelerometer is based on the piezoelectric effect: the accelerometer generates an electrical charge that is proportional to the acceleration. In combination with a differential charge amplifier this provides a complete and stable differential measurement chain that is not influenced by environmental factors such as electromagnetic interference.
