4.3 Description
The GEMÜ 1441 cPos-X is an intelligent, digital electro-pneu-
matic positioner in 2-wire technology used to control pneu-
matically operated process valves. It can be combined with
single acting or double acting linear actuators or quarter turn
actuators. This means that it can be used, among other
things, for diaphragm, globe and diaphragm globe valves as
well as for ball valves and butterfly valves, for instance. The
positioner has a robust housing with a covered LCD display
for status information. The positioner can be operated re-

positioner. As an option, the product can be ordered for a re-
mote mounting type, in which a separate travel sensor is con-
nected using an M12 connector. The travel sensor measures
the current position of the valve and reports it to the product's
