Construction
The GEMU 1436 cPos is a digital electropneumatic positioner with an optional integrated process controller for the control of liquids, gases and steam in conjunction with pneumatically operated process valves. The positioner exactly adjusts the stroke of the process valve. When using the optional process controller the signals from a process sensor (e.g. flow, level, pressure, temperature) are detected and the media adjusted according to the specified set value. A membrane keypad and backlit display are on the front of the housing whilst pneumatic and electrical connections are on the rear. Integrated pneumatic throttles enable the control air to be regulated in a way that the positioner can be set to suit different valve actuators and operating times.
