KTOE-JB5 series quartz flexure accelerometer is a medium accuracy accelerometer designed with unique structural dimensions (short). The product has excellent long-term stability, repeatability, dynamic response performance, good anti-vibration shock performance and high reliability, etc. It can be used for both static and dynamic testing, and is also a standard vibration sensor and inclination sensor. The product adopts a unique structural design and special circuit, the output current and the force or acceleration are linearly related, the user can select the appropriate sampling resistance through the calculation to achieve high-precision output. And according to the user's needs built-in temperature sensor, for the bias value and scale factor compensation, to reduce the impact of the ambient temperature.
Applications: Inclination testing of bridges, dams, oil wells, coal mines, etc., high-speed railroad control, and stability control of ships.
