High temperature and vibration resistance quartz flexible acceleration sensor KSJB4 is used in bridge engineering

KSJB4 series quartz flexible accelerometer is a kind of high temperature and vibration resistance accelerometer, the product has excellent repeatability, start-up performance, high temperature 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 seismic 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 offset 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 offset value 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

Application fields: bridge, dam, oil well, coal mine inclination test, high-speed railway control, ship stability control.
