inertial navigation system sensor - China accelerometer sensor - quartz accelerometer

Product Description

SNQ1 QUARTZ FLEXIBLE ACCELEROMETER

SINGLE AXIS l ANALOG OUTPUT



SNQ1 navigation grade quartz accelerometer with high range and high accuracy, long-term repeatability and excellent reliability. It is cost-effective inertial 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 of 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.



Features:

Excellent starting repeatability;

Good environmental performance;

Analog output;

Adjustable output range;

Built-in temperature sensor, output current linearly transformed with temperature (optional)
