High Precision Quartz Flexure Accelerometer with Temperature Compensation for Navigation
Product introduction
ACC1-Quartz Flexible Accelerometer- Datasheet-v3.2...
ACC1 series quartz flexible accelerometer is a high-precision sensor designed for exceptional long-term stability, repeatability, rapid startup performance, environmental adaptability, and high reliability. It is suitable for both static and dynamic testing and also functions as a standard vibration and tilt sensor.
The accelerometer features an output current that maintains a linear relationship with force or acceleration, allowing users to achieve high-precision output by selecting an appropriate sampling resistor through calculation. Additionally, the built-in temperature sensor enables bias and scale factor compensation, effectively minimizing the impact of ambient temperature fluctuations based on user requirements.
