Harsh environments are a fact of life in the world of energy production.  The CD52-316SS is a fully stainless steel version of CDI’s field-proven and ATEX/IECEx rated CD52 Bandit non-intrusive pig signaler. 

Sporting a new and shorter antenna measuring only 9.5" [241mm] in length, the CD52-316SS system may be deployed into very tight launcher and receiver locations.

The CD52-316SS’s detachable base makes installation simple. Rather than having to contend with the full weight of the system during installation, simply attach the base to the pipeline first and then bolt the antenna assembly to the base. The detachable base also provides a convenient way to retrieve the system for anti-theft or maintenance.

The CD52-316SS provides an either normally open or normally closed dry contact relay closure when pig passages occur, providing a simple and effective integration into existing SCADA systems. Conduit connections are made via standard ¾” NPT or M20 metric connections.

Visual indications include large, clear LCD segments which light upon passages and clear themselves automatically, as well as an optional Remote Indication System which may be seen to 100+ meters.

An optional 316 stainless steel sunshade may be added to the system to provide increased head shedding in deserts and other areas with high levels of direct sunlight. The overall temperature inside the cabinet is reduced, prolonging the life of the electronics (and batteries if used). Marine or other coatings may also be applied to the cabinet by request to further increase the CD52-316SS's corrosion resistance.
