1. Product description
ACC1 series quartz flexure accelerometer is a high-precision accelerometer with excellent long-term stability, repeatability, start-up performance, environmental adaptability and high reliability, which can be used for both static and dynamic testing, and is also a standard vibration sensor and inclination sensor.
The output current of the product is linearly related to the force or acceleration, and the user can select the appropriate sampling resistance through calculation to achieve high-precision output. A temperature sensor can be built-in according to the user's needs, which can be used to compensate the bias value and scale factor, and reduce the influence of ambient temperature.
