Kistler has introduced the accelerometer series 8740A and 8788A for vibration measuremetns in aviation and space testing.
The improved and more robust high-sensitivity IEPE accelerometers combine low weight and small size with minimal noise for more accurate vibration measurements. They come in ranges of 5g, 10g and 50g and feature wide frequency responses.
The single-axis accelerometers of series 8740A and triaxial accelerometers of series 8788A replace the types 8640A and 8688A series in the Kistler portfolio. While the housing design and the low mass stays the same, the series 8740A and 8788A differ from their predecessors in that they reach their high accuracy and low noise threshold through a ceramic shear element instead of P-Beam technology.
This technology also makes the new sensors much more robust. Their accuracy was improved even further by lowering the noise thresholds of the various g-ranges by up to 133% compared to their predecessors – resulting in the lowest noise thresholds on the market.
The 8740A and 8788A series were designed both for multiple channel modal analysis on small components and the testing of a range of larger structures. An IP68 integral waterproof cable for underwater testing is optionally available.
Thanks to threaded holes on each sensor, the sensors can be freely installed on test objects, which allows engineers to make use of each mounting side of the cube design while ensuring reliable mounting for the calibration.
