4.2 Description
The GEMÜ 1436 cPos digital electro-pneumatic positioner has
an optional integrated process controller to control pneumat-
ically operated process valves with single acting or double
acting linear or quarter turn actuators. When using the op-
tional process controller, the signals from the sensors (e.g.
flow, level, pressure, temperature) are detected and the media
adjusted according to the specified set value. GEMÜ 1436
cPos has a robust aluminium housing with protected operat-
ing keys and an LCD display which allows the product to be in-
dividually adapted to complex control tasks. With additional
equipment, the positioner can be used directly in fieldbus en-
vironments.
