Electro-Pneumatic Valve Positioner, Model ARCApro Typ 827
This report deals with the results of tests of two single acting electro-pneumatic valve positioners model ARCApro Typ 827, manufactured by ARCA Regler GmbH, Germany in co-operation with Siemens A.G. The instruments were standard production models. The instruments are fully identical to the SIPART PS 2, valve positioner, manufactured by Siemens A.G. Germany. One positioner was mounted on an ARCA actuator/valve assembly. This instrument was not completely evaluated, but the tests were chosen from the full evaluation programme to show the performance of this type when connected to the ARCA integral mounting. The other positioner mounted on a Von Rohr valve/actuator assembly was only submitted to the vibration test. For details on the full evaluation the WIB report E 2684 T99 must be consulted.
