Quartz Accelerometer Single Axis Inertial Vibration Sensor Low Bias One Axis Inertial Accelerometer
Product Introduction
AV1-02 series quartz flexible accelerometer is a kind of high temperature and earthquake resistant accelerometer, the product has excellent repeatability, startup performance, high temperature and earthquake resistance performance and high reliability, can be used for static test or dynamic test, is also a standard vibration sensor.
The product adopts unique high temperature resistance and seismic design, packaging technology and special circuit. The output current of the product is proportional to the measured acceleration, and the measurement of static and dynamic acceleration is provided. Users can select the appropriate sampling resistance through calculation to achieve high precision output, and the built-in temperature sensor can be used to compensate the offset value and scale factor according to user needs. Reduce the impact of ambient temperature.
Application: bridge, dam, oil well, coal mine dip test, high-speed railway control, ship stability control.

Installation requirements
The flange surface of the sensor is the installation reference surface.
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.
