clean design meets hygiene requirements in terms of air quality, as well as the permitted quantity and size of particles released. Simultaneously, energy consumption is reduced by up to 50% compared to using conventional drive technology for similar applications. Industries that will reap the maximum benefit here are food and beverage, chemical, phar- maceutical, cosmetics, medical and biotechnology, semiconductor and solar panel production. All these industries have sensitive production areas where high demands are placed on either hygiene or cleanliness, in order to prevent any form of contamination of the end product. Tradi- tional drive systems made it difficult to clean these areas as thoroughly as required. Standard drives, for example, have cooling fins in which dirt can ac-

cumulate and germs and bacteria distributed via air swirls. This is where the smooth-surface design of the MOVIGEAR mechatronic drive system comes into its own. Its geometric design was based on hygiene guidelines even at the concept stage. Not only is cleaning minimised, but system downtime is reduced and overall operating costs cut as a re- sult. The smooth surface is virtually self-cleaning, as it prevents dirt from adhering to it. Conclusion The MOVIGEAR mechatronic drive solution has been developed specifically for standalone solu- tions and applications requiring simple functionali- ty. DIP switches and potentiometers make for easy and fast start-up, as no PLC is required. The unit is controlled via binary inputs, either by a central PLC or in local/manual model. The MOVIGEAR AS-In- terface allows for simple fieldbus connection. Pa- rameterisable fixed speeds and ramps, integrated STO safety function and connection options for ex- ternal sensors ensure fast and extremely efficient implementation of materials-handling systems.

Any Size any Shape I.R. Windows

IRISS IR Windows can also be equipped with Delta T Alert sys- tems. When the temperature differences are above a pre-deter- mined level or significantly different from other electrical enclo- sures within the system the Delta T Alert will remotely alarm the support engineers, repair teams, etc. with details and the location of the temperature alarm.

I am sure you are aware of the small circular crystal thermal im- age windows offered by thermal imaging camera manufacturers? Would you like to use fewer windows, have a better field of view and access applications that other people think are impossible? If so, then please read on … Available from R&C Instrumentation , the IRISS Platinum Se- ries CAP-T has the largest visually clear infrared (IR) transmissive viewing area available. The exclusive pharmaceutical-grade rein- forced Poly-View System polymer allows any thermography cam- era to monitor completely undisturbed assets inside energised electrical equipment in the visual, UV and shortwave, mid-wave and long-wave IR spectrums. The larger rectangular viewing area provides an unparalleled field of view when compared to traditional round IR windows. The CAP-CT offers locking covers for your IR window. These are useful in areas of high traffic and protect the IR viewing panes from im- pacts, flying debris and dust. IRISS offer flexible innovation in IR window technology, no other manufacturer can offer, windows of any size or shape, even curved windows for Iso-phase bus applications. Meaning that IRISS win- dows can deliver on applications that no one else can get near to, offering you enhanced levels, of safety and ease of surveying. These windows work with all popular brands of camera and in addition we offer a lifetime warranty for added piece of mind.
