Product Description:
The KSJB5 series quartz flexible accelerometer is a medium precision accelerometer with a unique structural size (short) design. The product has excellent long-term stability, repeatability, dynamic response performance, good vibration shock resistance and high reliability, which can be used for static and dynamic testing, and is also a standard vibration sensor and inclination sensor.
The product adopts unique structural design and special circuit, the output current of the product and the force or acceleration are linear, the user can choose the appropriate sampling resistance by calculation, to achieve high precision output. The built-in temperature sensor can be used to compensate the offset value and scale factor to reduce the impact of ambient temperature according to user needs.
Application fields: bridge, dam, oil well, coal mine inclination test, high-speed railway control, ship stability control.
