What is the Technical Information of the Accelerometer?

With the development of inertial navigation system technology, the market share of accelerometers has gradually expanded and there has been a greater breakthrough in the field of accelerometer technology. A brief overview of the technical information related to accelerometers.

Sensing material

In the selection of accelerometer materials from the initial metal, ceramic, to now widely used silicon raw materials and quartz. From the raw material screening process, the material performance of quartz is better than that of metal and the fatigue resistance is high, so this accelerometer has higher accuracy, strong anti-disturbance ability, large measurement range and strong overload ability. At present, quartz accelerometers have been widely used in the measurement of various linear acceleration, vibration acceleration, speed, distance, angular velocity, angular displacement and other parameters.

Application features:

Oil logging field

Quartz accelerometer is one of the many accelerometers with relatively simple structure, performance, volume and price advantages. Especially in the high temperature environment of drilling and logging, it is an acceleration sensor that has been tested by a lot of actual downhole work experience, and has high temperature and high reliability product characteristics. For example, ER-QA-03D https://www.ericcointernational.com/accelerometer/quartz-accelerometer/accelerometer-for-oil-and-gas.html  quartz accelerometer designed for oil mining can work at a high temperature environment of 180℃ and the volume is only 25×21mm, its seismic resistance is 500-1000g 0.5ms, which has the advantage of overcoming complex environmental difficulties, so as to improve the efficiency of logging. The other ER-QA-03F https://www.ericcointernational.com/accelerometer/quartz-accelerometer/er-qa-6t-quartz-accelerometer-for-oil-and-gas.html also has the same operating temperature as 03D and is smaller to meet the strict requirements of space size equipment.

Inertial navigation system field

Inertial navigation system is an auxiliary navigation system that uses accelerometers and gyroscopes to measure the acceleration and angular velocity of objects, and uses computers to continuously estimate the position, attitude and velocity of moving objects. By detecting the acceleration and angular velocity of the system, the inertial navigation system can detect changes in position, speed and attitude. ER-QA-03A https://www.ericcointernational.com/accelerometer/quartz-accelerometer/accelerometer-for-aerospace.html is a high-performance quartz accelerometer with zero bias stability of 10-50μg, scale factor of 15-50 PPM, and second-order nonlinearity of 10-30μg/g2, providing accurate data information for the system.

Aerospace field

Quartz accelerometers can achieve high precision acceleration measurement with extremely high reliability and stability. Its special flexible construction enables it to adapt to high acceleration applications under various environmental conditions, such as high temperature, high pressure and high vibration environments. For example, in addition to the zero-bias stability of 10μg, the scale factor and second-order nonlinearity of the ER-QA-01A can also reach 10 PPM and 10μg/g² respectively. It is a good choice in aerospace applications.
