ER-02 Directional Gyro from Ericco International Limited thumbnail

ER-02 Directional Gyro

Multipoint directional gyro system with small diameter ER-02 model undersized Gyro-inclinometer is the third generation gyro system newly developed, it’s a multipoint directional gyro system. The characteristic of the third generation gyro system is that the outside diameter of external tube of pressure resistance is only 38mm, if with heat shield, the outside diameter is 45mm, which make the gyro system’s measurement range become larger and the temperature accommodation become wider.
