The ACC2 Series Vibration Acceleration Sensor is a high-precision, wide-range accelerometer capable of measuring up to ±100 g. It offers excellent long-term stability, repeatability, fast start-up performance, strong environmental adaptability, and high reliability.
The sensor is suitable for both static and dynamic measurements and can also serve as a standard vibration or tilt sensor. The sensor's output current maintains a linear relationship with the applied force or acceleration. Users can achieve high-precision output by calculating and selecting an appropriate sampling resistor.
Additionally, the built-in temperature sensor allows for compensation of bias and scale factor, effectively reducing the influence of ambient temperature as per user requirements.
