Semi Liquid Floating Torsion Bar Gyro

Features:
1.Be used directly without a matching circuit;
2.Strong anti vibration ability, high reliability and low cost;
3.Suitable for the flight control system, the speed measuring system and the servo system;

Product Details


The output of the semi liquid floating torsion bar gyro is proportional to the input angle rate of AC voltage signal, and it can be demodulated into DC signal, and it can be used directly without a matching circuit. The semi liquid floating torsion bar gyroscope has the characteristics of strong anti vibration ability, high reliability and low cost. It is suitable for the flight control system, the speed measuring system and the servo system. ER-7G replaced the French SAGEM floating gyroscope in a certain model. ER-18E has motor, frame self inspection function and strong anti vibration ability. It is mainly used in domestic key model flight control system.
