Product Description
The ACC1 series vibration acceleration sensor is a high - precision accelerometer boasting outstanding long - term stability, repeatability, start - up performance, environmental adaptability, and high reliability. It is suitable for both static and dynamic testing scenarios, serving as both a standard vibration sensor and a tilt sensor.
The product's output current exhibits a linear relationship with the applied force or acceleration. Users can, through calculation, choose an appropriate sampling resistance to ensure high - precision output. Additionally, a built - in temperature sensor is available for bias and scale factor compensation, mitigating the impact of ambient temperature as per user requirements.
