1. Product description
ACC3 series quartz flexible accelerometer is a miniaturized, high-precision, wide-range accelerometer with excellent long-term stability, repeatability, start-up performance, environmental adaptability and high reliability. It can be used for both static and dynamic tests. It is also a standard vibration sensor and tilt sensor.
The product adopts a unique miniaturization design and packaging process. The output current is linearly related to the force or acceleration. Users can select the appropriate sampling resistance through calculation to achieve high-precision output. The built-in temperature sensor can be used to compensate the bias and scale factor and reduce the influence of ambient temperature according to the user's requirements.
