Inertial Aerosystems announce the availability of a force rebalance accelerometer, designed for Industrial applications. Designated the QA-650 it incorporates the established Q-Flex etched quartz proof flexure seismic system. An amorphous quartz proof mass structure provides excellent bias, scale factor and axis alignment.
Integral electronics develop an acceleration proportional output with current providing both static and dynamic acceleration measurements up to 30g. With an appropriately scaled output resistor, the output current can be converted into a voltage. This product has long term stability, low noise and excellent long term bias repeatability.
The operating temperature is -55 to 96 degrees C with shock resistance exceeding 100g and vibration of 25g peak sine @ 5-500 Hz. Weighing only 65 grams maximum with a diameter of 26.54mm and a height of 15.67mm, it is ideal where space and weight is at a premium. Operating supply is +/-13 to +/-18 VDC
This versatile product has applications in automotive test instrumentation, braking system deceleration, bridge and building movement monitoring, industrial and robotics control, land vehicle navigation, trains and track testing and offshore drilling platform motion monitoring. It is particularly suited to GPS/INS navigation systems.
