What are high temperature accelerometers?

[Alisha Bridges]

High temperature accelerometers are designed to withstand harsh conditions and provide accurate data in demanding industries such as aerospace and oil & gas. Essentially, their purpose is to function effectively in challenging environments, including underground settings and extreme temperatures.



Manufacturers of high temperature accelerometers employ specific technologies to ensure the sensors’ reliability in extreme conditions. For instance, Ericco’s Quartz Accelerometer for Oil and Gas is proved to own high performance. This model utilizes an amorphous quartz proof-mass structure that reacts to acceleration through flexure motion, ensuring excellent stability in bias, scale factor, and axis alignment.



Some high temperature accelerometers also incorporate external amplifiers to safeguard the sensor from heat damage.



And we recommend the ER-QA-03D for oil and gas, whose operating temperature is -55~180 ℃, with an input range of ±30g, bias repeatability <50μg, and scale factor repeatability <80 ppm.
