Accelerometer combines low noise with wide frequency range

With six ranges from 2 to 200g, these new MEMS accelerometers can be used for most demanding applications – from automotive durability testing and road load data and aviation flutter testing to bridge structural monitoring and railway rolling stock testing and monitoring.

The Type 8396A accelerometer uses a MEMS variable capacitance, silicon sensing element to simultaneously measures acceleration and/or low-frequency vibration in three mutually perpendicular axes from DC to 2000Hz. The integrated signal amplifier provides a wide range of industry standard output signals options to interface with most current DAQ systems.

The sensing element and electronics are contained in a lightweight, hermetically sealed, welded titanium housing with either a circular 9 pin connector or an integral cable. Ground isolation is obtained by mounting the sensor using one of a range of off-ground accessories or by adhesive mounting using the side of the sensor with the integral hard anodised plate.

Kistler says the combination of a wide frequency range, low noise and operating temperature from -55 to +125°C, combined with small size and mass, make the new Type 8396A triaxial accelerometer suitable for applications wherever very low frequency measurements need to be made accurately, even under varying temperatures in exposed, outdoor environments.
