The reliability of the SCADA system 10 tips for best results

In the area of wireless communications today, there a battle urgent and serious to be delivered to the client property. customer property is all about creating and providing compelling value.

If you build an existing SCADA or just the first time, a test of how to create this value is directly in their hands, with construction on the system performance over the length and high quality service.

If we ignore the time preference radio, the most important key to the results of a reliable communication SCADA careful selection of antenna equipment.

Improved reliability Tenfold

parts hardened optimized assembly techniques, and specialty coatings, and installation procedures can be improved, in some cases, provide a ten times (10x) increase over the life of aluminum antennas TK.

Profitable

The Yagi-Uda, better known as the Yagi, is as excellent choice for antenna applications more remote site. Some SCADA systems can use up to 1000 Yagi pointing to an omnidirectional antenna, a configuration highly cost-effective to ensure broad geographic coverage, at minimal cost!

Given the continued exposure to the elements, however, susceptibility Damage caused by wind, weather, and in some cases, chemicals, remains high. We believe that the average time between failures (MTBF) of a scrutiny when the economic cost of field trip to replace broken or defective antenna may exceed $ 100 per hour. In a real sense, while increasing the average time between failures by investing in antenna technology can improve very quickly pay for itself.

In some case price 25% higher than the antenna equipment can prolong the life of your site operating from 12 to 24 months to 10 years depending on the installation in question!

Selection criteria

=> The antenna design and manufacturing process itself exerts the greatest influence in the long term performance and life of an antenna. Therefore, look for models that integrate well above resistant building materials and has well constructed.

Antennas => made from 6061 aluminum offers the best combination of strength and lightness.

=> Soldier models usually provide the greatest long-term performance because they are a part, both electrically and mechanically, in virtually all environmental conditions. In particular, avoid "press-fit antenna designs.

=> Pitting and corrosion occurs very quickly with raw aluminum, which causes rapid mechanical damage and power outage in just 2 years. Therefore, choose one with either heat-stable (powder coating) or anodizedsurface treatment, avoid those treated only with Chemical conversion coatings (Alodine).

What else to consider

=> In addition to antennas, special attention when choosing a power cable. In a typical SCADA system, the cable connecting the antenna to the radio box remains in the same environmental conditions as the antenna. It is recommended that the power cable from the antenna must match the life expectancy the antenna.

=> To maximize the overall life of the installation, use a UV resistant cable type low-loss RG-8 coax, preferably with polyethylene (PE III-A), a jacket and terminated with N type connectors with the wrong cable can cause reductions considerable effectiveness. Unable to recover these losses with any number of antenna gain or transmitter power.

=> Follow the manufacturer's installation instructions are usually included with each antenna.

=> Make sure that the stability of antenna; mastsorloose antenna slightly unstable, of poor quality clampscan create problems.

=> Require Application specific sealing if your own staff do the work, or which is done by a contractor

Customer Care => for installation procedures correctly, which contributes greatly to the general life of the facility.
