Introduction
The Sherborne Sensors’ range of Solid State Accelerometers measure vector acceleration with high
accuracy using a micromachined (MEMS) silicon sensor incorporating an air damping feature. Unlike
fluid damped devices the air damping employed is essentially independent of temperature. The
transducer also incorporates positive mechanical stops confering excellent shock resistance.
The accelerometer is compensated for the effects of temperature on both sensitivity and zero.
Typical applications include data acquisition systems, crash recorders, fatigue life monitoring and
prediction; monitoring and controlling deceleration in mass transit systems; road bed analysis and
fault detection equipment for high speed railways; military and civil flight simulators; autopilots and
low frequency vibration monitoring.
The A640 series will in many cases replace the now discontinued Schaevitz Series A400
accelerometers and is mechanically inter-changeable.
In addition to the instruments offered in this bulletin Sherborne Sensors design and develop
accelerometers for specific applications. These custom designed units can be manufactured and
tested to conform to specific requirements and standards.
