1.Introduction:
The high-performance quartz accelerometer for aerospace uses a monolithic integrated special gear speed Hall chip with good temperature characteristics and minimal drift. It is a reliable Hall-inductive proximity sensor (which can detect metal substances such as iron). Used in automotive and industrial high speed control products. It is suitable for sensing speed and precise spacing in demanding transmission and gearbox products. The speed sensor can also be equated with a precision high-speed proximity switch. The difference from the ordinary inductive proximity switch is that the sensing surface is magnetic.
High-performance quartz accelerometer with excellent bias stability and scale factor stability, can meet the demanding requirements of aerospace in use, performance indicators in years, reduce calibration work
Navigation guidance systems for missiles, aircraft, ships, and chariots must have speed and position information. In low-demand applications, people use airspeed meters, Mach number sensors, odometers, etc., but with the performance requirements of the weapon system. Improve, the above instruments can not meet the requirements. The line accelerometer can be installed in a moving object to directly measure its acceleration, and then obtain the speed and position. The measurement accuracy is high and the dynamic performance is good, which is much better than the airspeed meter and the odometer. Therefore, linear accelerometers are one of the most important applications for inertial navigation guidance systems.
