QUARTZ FLEXIBLE ACCELEROMETER
KT-JB1 QUARTZ FLEXIBLE ACCELEROMETER
Quartz flexible accelerometer series is a high-precision inertial navigation class accelerometer with excellent long-term stability, repeatability, start-up performance, environmental adaptability and high reliability. It can be used for both static and dynamic testing, and it is also a standard vibration sensor and inclination sensor.
The output current of the product has a linear relationship with the force or acceleration received. Users can select 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: inertial measurement of high-precision inertial navigation system and vibration isolation test of precision instruments and equipment in ships and other fields.
Features
1. Excellent turn-on repeatability performance
2. Environmentally rugged
