Navigation Grade Quartz Flexure Accelerometer With Temperature Sensor For Mapping
Product introduction
ACC1-Quartz Flexible Accelerometer- Datasheet-v3.2...
ACC1 series quartz flexible accelerometer is a high-precision 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 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.
