TEDS Accelerometers

Kistler has introduced a new family of single axis and triaxial lightweight, miniature PiezoBeam IEPE accelerometers with optional TEDS. Dimensionally the company’s smallest, lowest mass PiezoBeam IEPE accelerometer model, the single axis Type 8640A weighs 3.5 grams. Offered in ranges of ±5, ±10 and ±50 g with sensitivities from 1000 to 100 mV/g, it has a ceramic cantilever beam sensing element that is thermally compensated using patented methods, allowing it to emit an electrical charge proportional to vibration. The sensing element is enclosed within a hermetically sealed, welded titanium housing with low base strain sensitivity. An internal low noise charge amplifier provides a low impedance output with high amplitude and phase response over a wide frequency range and very good measurement stability. The device also features an integral 10-32 connector, as well as several mounting accessories, for easy installation into space constrained environments. For simultaneous vibration measurements in three orthogonal axes, the Type 8688A weighs 6.7 grams (for 1000 mV/g). Available in ranges of ±5, ±10 and ±50 g, with choice of 1000, 500 or 100 mV/g sensitivities, it incorporates PiezoBeam technology, with the ceramic cantilever beam sensing element enclosed within a lightweight, robust, welded titanium housing. Sensing elements are designed to provide high amplitude and phase response over a wide frequency range and are temperature compensated. An integral low-noise charge amplifier converts the charge signal to a proportional high level voltage signal. In addition, the triaxial accelerometers offer an industry standard 4-pin, ¼-28 connector, as well as several mounting accessories, facilitating easy installation into space confined areas, with the ability to mount the sensor on any of its three faces. Both models operate directly from an IEPE power source. Units are ground isolated when mounted with the optional twist-clip or adhesive adapter.
