Product Details Supplier Info More products

Kistler is offering piezoelectric and variable capacitive sensing technologies for flight test applications, including in-flight structural analysis, flight test simulator qualification testing, aircraft bay and equipment monitoring, weapons and stores testing, landing gear evaluation, simulated drop testing and aircraft flutter testing.

For flight test simulator testing, Kistler’s K-Beam MEMS variable capacitance accelerometers are mounted under the pilot seat to determine a simulator‘s vibration power spectrum density, with the aim of matching the actual vibration characteristics of the aircraft to be simulated.

After simulator commissioning, the same transducers are used to provide real-time data on the actual g-levels experienced by the pilot. If accelerometer data indicates that training limits are exceeded, the system shuts down automatically, providing an added safeguard.

Key information

  • The K-Beam range is offered in ranges from ±2g to ±200g and with frequency response from DC to 1,000Hz (five per cent).
  • The compact, lightweight accelerometers are available in either single-axis (Type 8315) or triaxial (Type 8395A) versions.
  • They incorporate a MEMS variable capacitance sensing element, consisting of a small inertial mass and flexure element sandwiched between two electrodes.
  • All sensors offer good thermal stability and reliability over an operating temperature range of -55°C to +125°C, with 6,000gpk shock survivability.
