Establishment for the purpose of recording the positions of Regulatory bodies, especially in refrigerant cycles

摘要

The device is intended for detecting the positions of shut-off or regulating members arranged in lengths of piping, in particular in refrigerant circuits. A by-pass line (1') with a restrictor member (3) is arranged on the two line connections (1) to the shut-off member (2). A temperature-change indicator (4) is provided behind the restrictor member (3) in the direction of flow. This change indicator (4) is provided with connections (5) for a signal processor, such as processor (8) with position indicator (7) and/or position transducer (14). IMAGE
