High Working Temp Quartz Flexible Accelerometer for Aeronautics
AV3 Series quartz flexibility Accelerometer is a compact, high-accuracy, large-scale Accelerometer with excellent long-term stability, repeatability, start-up performance, environmental adaptability and reliability, making it a cost-effective inertia grade quartz flexible Accelerometer.
The Accelerometeroutput 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.
Application measuring range: inertial measure and precision instrumentation of inertial navigation systems in the fields of aerospace, aviation, ships, weapons, etc.
