Design and principle of operation
Positioner with position transmitter
A positioner containing a position transmit-
ter cannot be equipped with integrated limit
contacts or an integrated solenoid valve
since the position transmitter requires most of
the space inside.
The position transmitter is used to assign the
valve position, i.e. the valve travel, to an out-
putsignalof4to20mA.
The tuning of the position transmitter ensures
that both end positions "valve CLOSED" or
"valve OPEN" as well as all intermediate po-
sitions can be signalized. Since the valve po-
sition is signalized independently of the in-
put signal to the positioner, the position
transmitter is a suitable option for checking
the actual valve position.
