PiezoBeam Type 8688A triaxial accelerometers from Kistler Instrument simultaneously measure vibration in three orthogonal axes. These miniature devices, which boast low mass, are available in measurement ranges of ±5 g, ±10 g, and ±50 g with sensitivities of 100 mV/g, 500 mV/g, and 1000 mV/g and optional TEDS capability.

The IEPE accelerometers are enclosed within a lightweight, hermetically sealed titanium housing with dimensions of just 0.492x0.492 in. Devices that have a sensitivity of 1000 mV/g weigh less than 6.7 grams. Each device employs a 4-pin connector and can be mounted on any of three faces.

Type 8688A accelerometers incorporate an integral ceramic cantilevered beam and a miniature hybrid charge amplifier. The low-noise charge amplifier converts the charge signal to a proportional high-level voltage signal with an output impedance of less than 500 ohms. Units are ground isolated when mounted with a mounting clip or adhesive mounting adapter.

You can use the Type 8688A accelerometers for multiple-channel modal analysis on small components and subsystems; vehicle testing in the aviation, aerospace, and automotive industries; and general-purpose vibration measurements. Sensors operate directly from the internal power source found in most FFT analyzers, Kistler Pieozotron power-supply couplers, or any industry-compatible power source.
