ER-QA-03D

Product catalog summary

Introduction
The ER-QA-03D series quartz flexible accelerometer is designed for high temperature and vibration resistance. It offers excellent repeatability, start-up performance, and reliability, suitable for both static and dynamic tests. The accelerometer features a unique design and packaging technology that ensures high precision output. It can include a built-in temperature sensor for bias and scale factor compensation, reducing ambient temperature impact. The product is compatible with QA650, T185, T160, and JAE series but uses a double torque structure for enhanced stability. It has been widely used since 2010, particularly in oil drilling applications.

Applications
The accelerometer is used for inclination angle tests in bridges, dams, oil wells, coal mines, and for stability control in high-speed railways and ships.

Catalog excerpts

ERICCO INERTIAL TECHNOLOGY Introduction ER-QA-03D series quartz flexible accelerometer is a kind of high temperature and vibration resistance accelerometer, the product has excellent repeatability, start-up performance, high temperature and vibration resistance and high reliability, can be used for static test or dynamic test, is also a standard vibration sensor. The product adopts unique high temperature and anti-vibration design, packaging technology and special circuit, the output current of the product is proportional to the measured acceleration, providing static and dynamic acceleration measurement, users can choose the appropriate sampling resistance through calculation, to achieve high precision output, and can be built in temperature sensor according to user needs, for bias and scale factor compensation, reduce the impact of ambient temperature. We can replace QA650, T185, T160, JAE series products in place, but we use double torque structure, which is different from other companies' products, can make the accelerometer bias and scale factor more stable, and have independent intellectual property rights. This product has been launched since 2010, and the number of deliveries has reached thousands. After years of application, it has become a mature product, especially for the measurement while drilling of oil drilling. Inclination angle test of Bridges, DAMS, oil Wells, coal mines, etc. Control of high-speed railways, stability control of ships, etc. Whatsapp/Wechat/Mob:8613992884879 Websit: www.ericcointernational.com E-mail: [email protected]
