high stability quartz flexibility accelerometer, quartz accelerometer scale factor 50g range inertial acceleration meter
Product Introduction
Quartz flexible accelerometer is a high-precision military inertial navigation grade accelerometer product with excellent long-term stability, repeatability, start-up performance, environmental adaptability and high reliability. It can be used for both static testing and dynamic testing. test, is also a standard vibration sensor.
The output current of the product has a linear relationship with the force or acceleration received, and the user can select an appropriate sampling resistor through calculation to achieve high-precision output. A temperature sensor can be built-in according to user needs, which can be used to compensate the offset value and scale factor to reduce the influence of ambient temperature.
