1. Product description
ACC2 series quartz flexible accelerometer is a high-precision,
wide-range accelerometer (up to 100g). The product has 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 output current of the product has a linear relationship with
the force or acceleration, and the user 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.
