Switches and sensors - free of cables in Ex zones: When Ex switches and sensors require no electrical cables and can transmit their signals beyond the Ex zone, then depending on the application in question the advantages can be considerable. More and more users are now opting for this technology – including and especially in sensitive application fields.

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.

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.

Exposing devices to extreme temperatures, saltwater, fouling, permanent vibrations, explosive atmospheres: tests in real-life conditions can be very telling. This is why steute opted to conduct a 1-year corrosion test at and in the North Sea for several of its switchgear series.

Ambient conditions can be extreme, whether in opencast mining or fertiliser production. Dust, damp, aggressive substances and vibrations all take their toll on equipment. Robust and resistant switches are therefore needed if human and machine safety are to be guaranteed. steute Technologies has recently extended its range of Extreme products to include a new emergency pull-wire switch and a new belt alignment switch.

Cold, heat, UV rays, saltwater: on the island of Helgoland in the North Sea, the conditions are tough. For one year, steute tested its switchgear products there. In conversation with P&A, steute representatives Rainer Lumme, Product Manager Extreme, and Carsten Both, Head of Industrial Development, explain how this came about, what results the tests produced, and why such tests are becoming increasingly important.
