Precision solid state accelerometers
06 April 2010
Sherborne Sensors has introduced the A640 series, a range of fully customisable, single-axis solid state accelerometers, offering precision measurement capabilities and available in ranges from ±1g to ±20g with ±5Vdc output. The A640 series features an advanced solid-state MEMS sensor, incorporating integral air damping. Unlike fluid-damped devices, air damping is essentially independent of temperature, which enables the accelerometer to perform reliably over a very wide temperature range (-40° to +100°C), with essentially zero temperature coefficient of damping ratio. Units are compensated for effects of temperature on both sensitivity and zero, and incorporate positive mechanical stops to aid shock resistance.
The range will operate from an unregulated dc power source and an unfiltered output offers a usable frequency response up to 600Hz, while an additional 5Hz low pass filtered output is standard on all units. Signal ground is isolated from power ground and electrical termination is via a military-style, bayonet lock connector. Units may be supplied with the output biased at 1g, to offset the effect of gravity. Other model variations are available upon request.
All Sherborne Sensors A640 series accelerometers are 100% tested and calibrated at the factory prior to shipment, and are accompanied by a two-year warranty.
