HAZARDOUS AREA EQUIPMENT FEATURE LED LIGHTING UPGRADE


Glamox has launched new generations of the FX60 range of Ex-protected LED floodlights and the TX65 range of explosion-proof (Ex de) multi-purpose LED area lights


also incorporate the latest versions of high-quality LED diodes with high reliability in an extended operational ambient temperature range. Furthermore, the cable entering the

ue to a new flat glass diffuser, both ranges now offer improved


performance and a more compact, protected design. When the first generation of FX60


LED floodlights was launched in 2014, it was a game-changer for hazardous area Zone 1 floodlighting. By replacing the glass dome with a flat glass, the latest generation has a significantly more compact and protected design, reducing exposure to external impacts in operational applications. The change in diffuser glass also


means a reduction in the internal air volume, which represents additional improvements, as the Ex-related dynamic test pressure of the lighting modules is reduced by 60 per cent. This, in turn, reduces the stress on materials and moulded joints in the manufacturing process. In extreme conditions with high


temperature fluctuations, lighting enclosures can experience humidity condensation due to repeated breathing (pressure alignment) between enclosure and ambient, even if the enclosures are tested to IP66 and IP67. A reduced internal air volume significantly decreases this breathing. The FX60 and TX65 Generation II

module is now moulded inside to avoid the effects caused by cold flow of cable insulators and subsequent breathing via cable entry. The cable is stripped down to copper wire strands to allow mould filler to flow in between strands. In addition, the cable entry is pressure tested. Both the FX60 and TX65 Generation


II deliver a comparable light distribution to the first generation, which means there is no need to make any corrections to existing lighting installations and designs. To withstand extreme operational


challenges, as well as a reduced air volume, the Generation II modules also include an O-ring between the glass and heatsink inside, as well as a gasket under the front bezel overlapping glass, mould and heatsink. The IC driver is relocated to the


centre of the LED PCB. As the driver circuit is based on semiconductors, the heat management system ensures a long operating life for the LED + IC driver system. The interconnecting wires between driver and LED are eliminated in this new design, therefore providing a sturdy and reliable connection in harsh operational conditions.

ompliant to the API 670 standard, these intrinsically safe probes are ideal for non-contact measurement of


shaft vibration position, position and speed in hazardous areas where potentially explosive gases or dusts are present. Typical applications will be on many types of critical and


reciprocating machines such as turbines, pumps, compressors, fans, motors, and gearboxes, across a wide range of industries including petroleum refineries, petrochemical and power generation plants. The versatility of eddy current proximity probes means they


can be used for numerous critical measurements, such as; relative shaft vibration and eccentricity, axial shaft position, thrust wear, differential expansion, shaft speed, over-speed, phase reference, reverse rotation, and rod drop monitoring. Measurement ranges are from 2.5mm up to 30mm. The probes are available in different formats, including;


reverse mount, for use in externally fitted through case probe holders; straight-threaded, usually mounted internal to the machine; and disc type, which are typically mounted on an adjustable bracket for axial measurements. They can be supplied with plain cables or armoured with


stainless steel convoluted hose and with extension cables where required. System cable lengths are five, seven or nine metres, and the driver unit can be configured at the factory to suit the application, or easily carried out on-site if preferred.
