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.

Customised user interfaces - Control systems in the OR

The proportion of control systems which are customised is growing rapidly. Preparations for the interoperable OR, where multiple medical devices are controlled via a central user interface, are also progressing at full speed. The benefits of customised user interfaces will be explored in this article.

User interface with integrated sensors

More functions for foot switches - The OR user interfaces of the future will be mechatronic integrated devices (MID) with special surfaces. Thanks to new production techniques, it is now possible to integrate conductive paths, sensors or antennas in the surfaces. Examples can be seen at the Medica.

OR.NET: for integration in the OR – SDC also with real-time data transmission

Some tasks in the OR require a real-time link between interoperable medical devices. Corresponding extensions to the SDC standard compiled by OR.NET are in preparation. At the Medica 2023, these extensions will be shown at the steute Meditec booth.

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.

Digitalisation of safety technologies

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.

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.

The benefits of remote control - Trends in user interfaces for medical devices

Medical devices in the OR are now usually connected to their corresponding user interfaces by remote control. This makes additional documentation necessary, but the advantages still far outweigh any disadvantages, and device manufacturers can purchase the systems with all the necessary approvals in place. Furthermore, radio technology is a prerequisite for interoperability in the OR: in the future, multiple medical devices will be operable via a single (wireless) user interface. First applications using this technology, known as SDC (Service-oriented Device Connectivity), are already available.

User interfaces: from manufacturer to service provider

Wireless user interfaces have multiple benefits, making them a popular choice in many medical disciplines. However, they also involve a higher level of effort for device manufacturers with regard to testing and documentation than cabled controls – unless the supplier is MDR-ready and able to provide the user interface with all the relevant documentation.
