Kistler’s Type 8688A integral electronics piezoelectric triaxial accelerometers feature an optional Transducer Electronic Data Sheet and measure vibration simultaneously in three orthogonal axes. They come in ranges of ±5 g, ±10 g, and ±50 g, with a choice of 100, 500, or 1000 mV/g sensitivities. They incorporate PiezoBeam technology, with an integral ceramic cantilevered beam, enclosed within a lightweight (less than 6.7 g for 1000 mV/g), robust, welded titanium housing. An integral low-noise charge amplifier converts the charge signal to a proportional high-level voltage signal, at an output impedance of less than 500 ohms. Applications include multichannel modal and structural analyses of small components or subsystems, aerospace and automotive vehicle testing, and vibration sensing applications, particularly those where mass loading may be a concern.
