Product Description

High-Precision Quartz Accelerometer for Inertial Navigation Replacing QA3000

 

Product Introduction

AV3000 is a high-precision quartz accelerometer developed by our company using independent core technology, which completely replaces QA3000 in function and has better accuracy.  Quartz flexible accelerometer series is a high-precision inertial navigation class accelerometer with excellent long-term stability, repeatability, start-up performance, environmental adaptability and high reliability. It can be used for both static and dynamic testing, and it is also a standard vibration sensor and inclination sensor.
The output current of the product has a linear relationship with the force or acceleration received. Users can select the appropriate sampling resistance through calculation to achieve high precision output. And according to user needs built-in temperature sensor, used to offset value and scale factor compensation, reduce the impact of environmental temperature.
Applications: inertial measurement of high-precision inertial navigation system and vibration isolation test of precision instruments and equipment in aerospace, aviation, ships, weapons and other fields.

Precautions
The sensor is a wearing part. Please handle it with care and do not drop or touch it. The impact and vibration shall not exceed the technical requirements of the product. The sensor shall be packed reliably during transportation, and there must be no less than 20mm of buffer foam around it, and the sensor shall be fixed with foam. When multiple sensors are packed, ensure that they do not collide with each other.
Before power-on, check the wiring of each pin, which shall not be connected incorrectly.
The product is stored in the original packaging box in a dry and ventilated environment. Handle with care when moving.
Pay attention to electrostatic protection.
