KiVibe Miniature triaxial IEPE accelerometer

Trends toward miniaturization and lightweight construction in various industries, including aerospace, the automotive industry, and the electronics industry, are placing new demands on test scenarios such as vibration testing. Limited installation spaces and increasing complexity – due to the integration of additional functions into smaller spaces – as well as the reduced weight of the structures being tested require innovative testing solutions. It must be ensured that all required tests can be conducted without any loss of precision.

Sensor technology for vibration testing (vibration tests, structural tests, modal tests) must integrate seamlessly into compact installation spaces and – without unnecessarily adding mass to the test object – deliver high-precision, stable output signals.
 

KiVibe Miniature the world’s lightest miniature triaxial IEPE accelerometer with a measuring range of 100 g (50 mV/g), 250 g (16.6 mV/g), 500 g (7.7 mV/g) and 1,000 g (3.6 mV/g) – featuring minimal mass and maximum sensitivity for its size. Specially developed microelectronics equipped with an application-specific integrated circuit (ASIC) from Kistler make it possible to implement this unique measuring range with an installation space of just 6 x 6 millimeters and a mass of only 0.9 grams including cable connector.

The miniature IEPE accelerometer contains in-house grown PiezoStar crystal with very low temperature sensitivity shift. This unique sensing element is combined with newly developed electronics to provide a broad frequency bandtwidth. Because of its inner structure the sensor is case isolated and therefore resilient to electromagnetic environment making it the ideal choice for vibration measurements close to electric motors or power supplies. The KiVibe Miniature is equipped with an integrated, flexible cable designed for reliable installation in tight spaces.

The unique combination of a series of important characteristics qualifies our miniature sensor for various vibration tests on lightweight structures where size and weight are critical:

• In small component qualification testing
• In the space industry, e.g. on nanosatellites, CubeSats, its components and their payloads
• In the aviation industry
• In the automotive industry
