Intelligent Positioner

Transcription

1 Intelligent Positioner Construction The GEMÜ 1 µpos is a digital electro-pneumatic positioner for process valve control. Designed for simple, safe and quick use with valves with strokes < mm. The positioner, travel sensor, switching valves and status LEDs are integrated in a solid compact housing with transparent cover. Pneumatic and electrical connections are in one mounting direction to save space and enable easy access. Features Simple use and operation Direct or remote positioner mounting to the process valve For single acting normally open or normally closed linear actuators Multiple point calibration for optimum valve adaption Optimized initialisation and valve control Advantages No air consumption when idle Simple mounting to various valve actuators Simple commissioning due to automatic initialisation speed -AP function for fast mounting and initialisation Simple operation, no settings necessary Dimensional drawing [mm] X 1 µpos
