Product Description

Quartz flexibility Accelerometer with high accuracy and large-scale

 

Product Description

 

AV2 Series quartz flexibility Accelerometer is a high accuracy, large-scale Accelerometer (up to 100g), excellent long-term stability, Repeatability, start-up performance, environmental adaptability and reliability make it a cost-effective inertia grade quartz flexibility Accelerometer.
The Accelerometer output current and the force received are linear output, and the user can select the appropriate sampling resistor to achieve the highest accuracy output. At the same time, the Tempe Sensor is built in, and the output current changes linearly with temperature. The user compensates the Deviation value and Scale factor to reduce the temperature effect (optional). The product can be used for both static and dynamic testing and is a standard vibration sensor.
Applications: Inertial measurement and precision instrumentation for high accuracy inertial navigation systems in aerospace, aerospace, marine, and weapons

Application: bridge, dam, oil well, coal mine dip test, high-speed railway control, ship stability control.

Installation Instructions

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.
