Wireless networks are computer networks that are not connected by cables. Wireless networks enable organisations to avoid the expensive and invasive process of introducing cables into buildings or connecting equipment in different physical locations. The basis of wireless systems are radio waves.
For hazardous industries such as PetroChemical and Pharmaceutical industries to access and enjoy the benefits of a wireless area network certain safety measures and specialized equipment need to be used. The risk in a hazardous environment exists where there is a potential for a spark to occur and ignite flammable gasses and vapours. In these areas the wireless access point needs to be intrinsically safe to reduce and eliminate the occurrence of a spark or possibility of ignition. A wireless access point (AP) is a device that allows wireless devices to connect to the network. As such it is a point where energy transfer and the potential to spark and cause an explosion exist in an environment where there are highly flammable fumes and gasses.
MTL Instruments, leader in the field of Intrinsic Safety, is the first to introduce Intrinsically Safe “Power over Ethernet” (PoEx™). This is revolutionary technology enables a single cable connection for Industrial Ethernet devices which is suitable for mounting in all hazardous area environments. The range, comprising Ethernet switch, serial gateway, wireless access point, and media converter – are all suitable for Zone 1 and Division 1 mounting and combine with a Zone 2 mounted power supply and isolator unit.
Wireless Access Unit 9469-ET is a versatile device that can be used as a Wireless Access Point, it allows wireless devices to connect through it onto the wired Ethernet network, either in AD-HOC or Infrastructure modes.
