QUARTZ FLEXIBLE ACCELEROMETER
KT-JB5 QUARTZ FLEXIBLE ACCELEROMETER
KT-JB5 series quartz flexible accelerometer is a middle grade precision accelerometer with unique structural size (short) design. The product has excellent long-term stability, repeatability, dynamic response performance, good vibration and impact resistance and high reliability. It can be used for 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 product output current and the force or acceleration is linear relationship, users can choose the appropriate sampling resistance through calculation, to achieve high precision output. And according to user needs built-in temperature sensor, used to offset value and scale factor compensation, reduce the impact of environmental temperature.
Applications: bridge, dam, oil well, coal mine dip test, high-speed railway control, ship stability control.
