MEMS accelerometers feature wide temperature rangeInertial Aerosystems' range of analogue and digital MEMS accelerometers now benefits from increased temperature capability. Fully rated at -55 to +125degC, they operate well in high-temperature, high-shock environments. This high-quality range is manufactured by USA-based Silicon Designs.

These integrated accelerometers are packaged in a miniature 8mm square, hermetically sealed package, which combines a micromachined capacitive sensing element with a custom integrated circuit that includes a sense amplifier and a sigma-delta A/D convertor. In the case of the low-noise analogue device, a sense amplifier and differential output stage are included.

All products are relatively insensitive to temperature changes and thermal gradients, and every model has a serial number on its bottom surface for traceability. Commercial, unscreened and mil-spec versions are available.

Full-scale ranges of + or -2 'g' to 400 'g' are standard and every device responds to DC and AC acceleration. Suitable for use where space and weight are at a premium, the units survive 2000 'g' shocks.

Applications include machine control, robotics, instrumentation, crash testing, vibration monitoring and analysis, while the low-noise analogue products are suitable for seismic monitoring and earthquake detection.
