Portable Gas Analyser is Certified as Intrinsically Safe
Servomex Group has introduced the intrinsically safe Servomex 5100 i.s. to its range of new portable analysers. The 5100 i.s. portable oxygen analyser provides a replacement for the popular 570A hazardous area analyser, with a standard and high accuracy version available.
The infrared version is described as the first intrinsically safe infrared analyser, providing a single % level measurement for 0–10% CO2 and 0–25% CO2. Other CO2 ranges and also a full range of CH4 and CO measurements will be made available.
Considerably smaller and lighter than the 570A, the 5100 i.s. uses proven non-depleting magnetodynamic paramagnetic or infrared sensing technologies (depending on the gas being detected) to ensure high reliability and a low cost.
Typical applications for the Servomex 5100 i.s. include combustion optimisation in hazardous areas, natural gas processing, use in refineries, checking centrifuges prior to start-up, HyCo facilities, catalytic cracker regeneration, inerting in tank farms and other general process monitoring.
The Servomex 5100 i.s. analyser has ATEX and IECEx approvals for use in hazardous areas. Other key hazardous area certifications have been applied for. It also has a rubber-overmoulded casing that dissipates static to prevent potentially hazardous static electricity build-ups and also provide additional physical protection. Long-life rechargeable lithium ion batteries are installed as standard and an integral electronic notepad enables data to be stored for subsequent analysis.
Customers have a broad choice of options to enable them to configure the instrument to suit their needs and can also as an option have the unit supplied with a carrying case. Extra options will be available during 2006 and range from an internal pump and a flexible sample tube, to a sample gas panel kit approved for use in hazardous areas and a filter and probe holder assembly.
For oxygen measurements, the Servomex 5100 i.s. utilises a proven, non-depleting paramagnetic sensor cell that is optimised for portable applications, while temperature compensation is built into the analyser's digital electronics. Unlike electrochemical cells, users can be confident that the analyser will always be ready to use. Moreover, the sensor cell should never need replacing, which simplifies maintenance procedures and reduces the cost-of-ownership.
Infrared sensor technology is used to measure CO2, CO or CH4. Again, says Servomex, this is proven, robust, non-depleting technology that delivers good accuracy and specificity in portable applications, even in the presence of flammable and toxic samples.
