Select the right valve position monitoring system - Switches and sensors for complex applications

Valve manufacturers have a wide choice when searching for suitable switching equipment to monitor valve positions. Different types of electromechanical switches and non-contact sensors are available, with series suited to explosive zones, corrosive environments and subzero applications. In many cases it can be beneficial to opt for wireless switches, including in Ex zones.

Explosion protection meets machine safety - Safety switchgear for special requirements

Safety switching devices used in Ex zones have to meet two different sets of complex requirements: explosion protection and machine safety. Designers also have to choose between different types of construction and different active principles. This is true for both heavy-duty applications and machines used for the processing and packaging of e.g. (dust-)explosive foodstuffs.

Machine safety and Ex protection

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.

Emergency pull-wire switch passes test in gravel plant

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.

Explosion protection and plant safety: a two-fold challenge. Machine safety in special environments

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.
