Abstract NE 4 ‘Mounting of Positioners/ Position Transmitters to Actuators’
This NAMUR-Recommendation specifies a construction design which enables an uniform mounting of positioners to various types of actuators by using an adapter. The adapter determines the correct orientation of the positioner in relation to the link to the push rod of the actuator. The design of the adapter ensures the firmly attachment in the correct positional arrangement to the different types of actuators.
