Navigation Grade Quartz Accelerometer Vibration Sensor Q-Flex QA-3000 Replacement

Navigation Grade Quartz Accelerometer Vibration Sensor Q-Flex QA-3000 Replacement

• Product Description

  ACC1 series vibration acceleration sensor 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.
