Introduction
The Sherborne Sensors’ range of Solid State Accelerometers measure vector acceleration with
high accuracy and incorporate a micromachined piezo-resistive strain gauge bridge 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.
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.
Designed for operation from an unregulated DC power source, the A545 is packaged in a
robust aluminium alloy housing with solder pin connections. The accelerometer has a widerange
useable frequency response from DC to several kHz.
