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. .
