What enclosure version is suitable for the application? Do the built-in devices satisfy the required functions and standards? And what combination of components is even permissible for the zone concept in question?
Weidmüller’s explosive risk zone experts answer questions like these every day. Based in the global application centres, they oversee projects from the initial planning stage to ongoing system operation. Their customers primarily come from the oil, gas and chemical sectors. The applications range from decentralised measurements to the safety-related switch-off of system parts.
“The growing complexity of systems in Ex zones means that solutions need to be increasingly multi-layered. With our Control Station Large, we’re therefore offering the opportunity to incorporate
Depending on the environmental conditions, the Control Station Large enclosure can be made of electropolished stainless steel, powder-coated aluminium or fibre-glass reinforced polyester
multiple functions in a single enclosure in such a way that suits the application at hand,” reports Product Engineer Holger Lafond. “We combine various command transmitters and status indicators with electronic components such as transmitters and fieldbus distributors in a manner tailored to the specific requirements and wire them to connection terminals in the enclosure. Our customers receive a turnkey plug-and-play solution – including all the approvals required.”
Combinations of various command transmitters and status indicators with electronic components such as transmitters and fieldbus distributors are developed and manufactured to the specific requirements of the customer
The Control Station Large is based on the proven Weidmüller enclosure system and has been tested and certified pursuant to ATEX and IECEx, to name but a couple of examples. Depending on the environmental conditions and the customer requirements, the enclosure can also be made of electropolished stainless steel (Klippon® TB), powder-coated aluminium (Klippon® K) or fibre-glass reinforced polyester (Klippon® POK). While corrosion-resistant stainless steel variants are preferably put to use in oil and gas refineries, the benefits of aluminium enclosures in terms of weight and stone impact resistance can be put to full use in the gas transport segment.
Other application products from Weidmüller are also based on the same design as the Control Station Large: the Control Station Small as a compact on-site control station and the classic distribution enclosure with terminal blocks. This means a project can be consistently managed from a single source, with a consistent quality level and design.
