Description

SNQ1 navigation grade quartz accelerometer with high range and high accuracy, long term repeatability and excellent reliability. It is cost-effective navigation grade accelerometer, widely used by global customers.

Its output current and force are linearly outputted. Users can calculate, select the appropriate sampling resistance, and achieve the highest precision output. At the same time, the temperature sensor is built in, users can compensate Bias and Scale factor, reduce the effect from temperature.

Application field:
It is mainly used in inertial navigation systems, in the fields of aviation, aerospace, ships, military, etc. It can be used for both static and dynamic testing, also it is a standard vibration sensor.
