Machines which are constructed for mechanical process engineering applications in explosive zones have to meet not one, but two demanding sets of rules and standards. They are – for good reason – subject to both machine safety requirements and explosion protection requirements. At the Powtech, steute will be showing switching devices for this special combination of demands – and presenting a new product.

As digitalisation progresses, cybersecurity is a major topic of discussion, and rightly so. Safety technologies have also moved on considerably in the course of this development. Dipl.-Ing. Rainer Lumme, Product Manager Extreme at steute Technologies, explains the changes in an interview with Andreas Mühlbauer.

At a gravel plant in Vennebeck, gravel freshly extracted from the River Weser has to travel a considerable distance on conveyor belts from the floating-grab excavator to the processing and grading machinery. The responsible persons at the gravel plant are currently testing a new series of emergency pull-wire switches.

Machine safety in explosive zones: switchgear required for this field must comply with two complex sets of regulations. Although this is a "niche within a niche", different options are still available when selecting safety switches and sensors. This is true for heavy-duty applications, but also for machines performing duties such as processing or packaging dust-explosive foodstuffs.

Wireless switching devices are not yet widespread within the oil & gas industry. And yet wireless technology offers this sector some particular advantages – provided that explosion protection is guaranteed.

Adverse ambient conditions must be taken into account during the development of switching devices for extreme applications, and must also be tested as first prototypes are produced.

Emco Wheaton loading systems are used all around the world for the handling of large quantities of petrol, natural gas, liquid gas, chemicals, etc. The company, which is based in Kirchhain near Marburg, monitors the positions of its loading arms using Ex position switches which are reliable in the long term, even in subzero temperatures.

Position switches used to monitor the step treads of part of the light railway system in the city of Bielefeld were increasingly failing, making higher levels of maintenance necessary. The operator MoBiel started looking for an alternative solution – and found one very close by. Following a successful test phase, the trains are now being successively fitted with long-life position switches.

A new series of emergency pull wire switches demonstrates the benefits of modular construction in electromechanical switchgear. This switchgear series can withstand extreme ambient conditions, can be used universally and is highly versatile with regard to installation, mounting and integration in existing equipment.

Petrol, natural gas and liquid gas are typical products handled using loading systems manufactured by Emco Wheaton. These loading systems are frequently to be found at the end of a process chain, at production sites or logistics stations like fuel depots or, in "ship to shore" applications, at ports.

At its Neuhof-Ellers site near Fulda, the company K+S Kali mines raw potash and magnesium salts at depths of down to 800 metres. The atmosphere in the flotation plants which separate the potassium chloride from the rock salt and other mineral salt constituent parts is extremely corrosive. Trust is therefore placed in "Extreme" emergency pull-wire switches which have been thoroughly tested and which allow the plants to be switched off very fast should a dangerous situation occur.
