lived:New generation of robust fluorescent lights for hazardous areas

Waldenburg – Introducing IS1+, R. STAHL presents a key innovation for the leading explosion-protected remote I/O system IS1. IS1+ now provides various additional features to address current and future requirements. In recent years, IS1 has maintained technology leadership in hazardous areas through many innovative new functions, including Fast Ethernet connection, PROFIBUS redundancy, DTM support, integration of optical rings and modules with integrated magnetic valves. While it surpasses these features already at its market introduction, IS1+ also places high priority on protecting previous investments in existing plants and machinery. The new I/O modules are fully downward compatible to their predecessors, allowing users to exchange or upgrade legacy devices without any changes to project planning and wiring.

Safe vibration detection in hazardous areas increases plant availability

R. STAHL, a leading international provider of safety technology, offers a wide range of warning systems for worldwide use. By means of audible and visual signals, these devices alert users to malfunctions in time, thereby ensuring optimal safety e.g. in fire protection systems and other monitoring facilities.

The PC-based, explosion-protected operating systems from the Open HMI series can now, on request, be fitted with innovative 15" displays that reduce glare and reflections to a minimum. The displays of these models can be read easily even in bright sunlight, since a filter pack effectively diverts even strong incoming ambient light. The new solution is based on a very effective combination of polarisation filters placed on top of and behind one another in front of the display.

An Uninterruptible Power Supply is mandatory on oil rigs: for safety reasons, the signal lighting must be operational at all times. Tasked with designing a UPS solution for an offshore rig off the African coast, R. STAHL was faced with three challenges. The UPS system not only required protective measures against explosive atmospheres, but also had to be adapted to the great heat and maritime climate at the rig's location.

R. STAHL's Yodalex series includes a wide range of signalling devices for hazardous areas, such as the YO6 omni-directional horn, the V6 beacon and the YL6 combination unit. All units feature an IP66 aluminium housing with machined flame paths which provides “ex d” ignition protection (flameproof enclosure).
