CMS and ATLAS have several cooling systems underground and on the surface with manifolds that need to be operated manually. In these manifolds, there are several high-pressure valves which are purely mechanical parts.
The aim of the switch support is to be able to install on each valve a simple switch in order to allow the monitorisation of the valve position from a SCADA platform without the need to be on-site.
For this purpose, six prototypes have been developed to cover the needs of the two different diameters currently used, including also the three logic signals needed depending on the need of having an “Open”,”Closed” or “Open+Not Closed/Not Open+Closed” signal.
