1. Product description
The ACC5 Series Quartz Flex Accelerometer is a medium precision accelerometer with a unique structural size (short) design. The product has the characteristics of excellent long-term stability, repeatability, dynamic response performance, good anti-vibration impact performance, high reliability and the like, can be used for static test and dynamic test, and is also a standard vibration sensor and tilt sensor.
The product adopts unique structure design and special circuit. The output current of the product is linear with 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.
