Sherborne Sensors A545 Series Biaxial and Triaxial Solid State Linear Accelerometers

Product catalog summary

Features

Available in ranges from ±2g to ±500g with integral overload protection.
Critical damping ratio of 0.7 nominal with minimal temperature coefficient.
Incorporates integral temperature compensation and is suitable for both DC and AC acceleration applications.
Available in bi-axial and tri-axial versions.

Introduction

The Sherborne Sensors’ A545 series are multi-axis accelerometers designed to measure vector acceleration in three perpendicular planes with high accuracy. They use piezo-resistive strain gauge bridge sensors with air damping, which is temperature-independent, and include mechanical stops for shock resistance. The accelerometers are temperature compensated for sensitivity and zero effects, making them suitable for applications such as biomechanical investigations, crash tests, and vibration analysis. They operate from a DC power source and are housed in robust aluminum alloy with solder pin connections.

Unlike fluid damped devices, the air damping employed 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. Typical applications include biomechanical investigations, data acquisition systems, crash test, impact, shock and vibration analysis. 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. 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. .
