Quartz Servo Accelerometers High Accuracy Accelerometers
Applications
Introduction
The product adopts unique miniaturization, high temperature and seismic design, advanced packaging technology and special circuits.
The flow is proportional to the input acceleration, and the user can select a suitable sampling resistor by calculation to achieve a high-precision output. And
Built-in temperature sensor according to user needs, which can be used to compensate for offset value and scale factor to reduce the impact of ambient temperature.
Application areas: oil drilling inclination measurement and vibration isolation testing of precision instruments.
