Quartz Servo Accelerometer: A general introduction

What is a Quartz Flexible Accelerometer?China Professional Quartz Accelerometers supplier-Hitech Sensors Tech Co., Ltd

Quartz flexible accelerometers are piezoelectric accelerometers that use quartz crystals as sensing elements. The operating principle of a piezoelectric accelerometer is that when a piezoelectric material (such as quartz crystal) is subjected to an external force, an electric charge proportional to the applied force is generated. A quartz flexure accelerometer measures acceleration by detecting the charge and converting it into a corresponding electrical signal.

Components and Working Mechanism

The main components of a quartz flexible accelerometer include a quartz crystal, a force harvester (or mass), and an amplifier circuit. The force harvester is attached to the quartz crystal, then the quartz crystal is fixed to the housing of the accelerometer. When the quartz accelerometer is subjected to acceleration, the force harvester exerts pressure on the quartz crystal, generating an electrical charge. This charge is then amplified by an amplifier circuit and transformed into a voltage signal that is easily processed and analyzed.

Quartz flex accelerometers use flexure elements in their design. These elements act as both a mechanical amplifier and a low-pass filter, providing excellent sensitivity and low noise. The quartz flexible design enables the quartz accelerometers to achieve high resonance frequencies, which is crucial for accurate measurements in high-frequency applications.
