The A545 range of multi-axis accelerometers measure vector acceleration in two or three mutually perpendicular planes with high accuracy and incorporate piezo-resistive strain gauge bridge sensors incorporating air damping. Unlike fluid damped devices, the gas damping employed in the A545 is essentially independent of temperature. The transducer also incorporates positive mechanical stops conferring excellent shock resistance. The accelerometer is compensated for the effects of temperature on both sensitivity and zero. Designed for operation from a DC power source, the A545 is packaged in a robust aluminium alloy housing with solder pin connections. The accelerometer has a wide-range useable frequency response from DC to several kHz.
