Abstract
The utility model discloses a monoblock type hybrid integrated double-speed axial angle/digital converter which comprises a two-way casting / number conversion circuit and a double-speed processing circuit. The two-way selsyn synchro or the rotary transformer formal axial angle signal are simultaneously converted into the highest 20 steric binary digital quantity which represents the angle and are exported according to a certain velocity ratio (1:8-1:64). The monoblock type hybrid integrated double-speed axial angle/digital converter uses the metal casing to enclose. Compared with the traditional converter with the plastic casing, the monoblock type hybrid integrated double-speed axial angle/digital converter improves the radiation efficiency and decreases the volume and reinforces the interference resistance ability, impact and vibration resistance ability. The monoblock type hybrid integrated double-speed axial angle/digital converter improves the reliability of the converter.
