The Ex-Controller-/Limiter devices of the IRB2M-Series are a combination of mechanical 2-point capillary temperature controller/limiter. The black glasfibre-reinforced polyester enclosure as well as the stainless steel enclosure is very rugged and is used as a junction box for single core heating cables also. The combination of controller and limiter allows an easy and space-saving application for electrical trace heating in hazardous areas for controlled design in accordance to 60079-30. The sensors with 4mm outer-diameter are particularly suitable for
mounting on pipelines or containers.
