An Engineeringtalk guide
Start with the news release
Inductive sensors meet safety standards from
IFM Electronic, which we summarised at the time by saying "IFM Electronic has developed a range of fail-safe inductive sensors that are fully compliant with the latest standards for safety-related parts of the control system. ".
Several months prior to that,
we featured the news release Micropilot radar offers overfill protection from
Endress+Hauser: "Endress+Hauser's Micropilot M FMR244 radar offers overfill protection in liquids and solids applications across the food and beverage, chemical, primaries and water industries. ".
In July 2009, we covered the news from RTK Instruments
- take a look at RTK SIL2 annunciator is certified to IEC61508
which says: "RTK Instruments is launching its SIL725 safety annunciator to provide high safety integrity for critical alarm applications and for use as a component part of a safety instrumented system. ".
Take a look also at the news release from IFM Electronic, IFM introduces Smartline AC030S,
as well as C4000 light curtain provides personnel safety from SICK (UK),
and Yokogawa enhances Prosafe-RS platform from Yokogawa UK.
