ER-GT-102 High Precision Gyro Theodolite
The product can find north with ultra-high precision, and its measurement principle is the integration method, which has the characteristics of strong anti-interference ability and high stability. The gyro-theodolite adopts an integrated body design (built-in battery), compact structure and stable performance. It has the functions of low position lock, automatic zero position observation, automatic north finding, automatic limit position, wide temperature compensation, etc. It is gradually iterating the limiter to provide the north finding accuracy of the reference plane azimuth and reduce the north finding time.
The product adopts DC permanent magnet gyro motor, which can reduce the temperature rise of sensitive parts of the gyro and improve the stability of the equipment. The application of gyro fast braking technology can prolong the service life of the gyro motor, so that the instrument does not need to wait and can run continuously, with auxiliary functions such as deflection body, calibrator, and straightening.
In tunnels and other excavation projects, the measurement of the center line in the pit generally adopts a long distance wire which is difficult to guarantee the accuracy, especially in the case of shield excavation. Starting from the short reference center line of the pit, there must be a high accuracy of angle measurement and station shifting. In the measurement, the corresponding inspection of the ground and underground should be often carried out to ensure the measurement accuracy. Especially in dense urban areas, inspection conditions are difficult and it is impossible to carry out excessive inspection operations. If the gyrotheodolite can be used to obtain an absolutely high precision bearing datum, and can reduce the cost of very high detection operations (minimum checkpoints), it is a very efficient centerline measurement method.
