The quartz vibrating beam accelerometer is designed based on the vibrating beam principle. It typically utilizes a vibrating beam made of quartz material (usually a small quartz beam) to sense acceleration. The frequency of the vibrating beam changes with acceleration, and this change can be detected by an electronic system.
Basic Operating Principle:
- Vibrating Beam: The accelerometer contains a fixed quartz beam that vibrates at a certain frequency. When acceleration is applied to the accelerometer, the motion of the beam alters its vibration frequency.
- Frequency Change: The vibration frequency of the beam is directly proportional to the applied acceleration. As the acceleration changes, the deformation of the vibrating beam causes a change in its vibration frequency, which is detected and converted by the electronic circuit to calculate the acceleration.
- Measurement Method: Quartz vibrating beam accelerometers typically offer high sensitivity and stability, making them suitable for high-precision acceleration measurements.
