Emerson has released two new open path gas detectors, the Rosemount 935 and Rosemount 936, which offer worker and property protection in extreme environments.<\/p>\n\n\n\n
Both easy-to-install models, the company said, can trigger alarms for toxic and combustible gases across wide areas and also reduce downtime through performance reliability; they are designed for both heavy vibration conditions and operating temperatures ranging from -55 Celsius (-67 Fahrenheit) up to 65C (149F). <\/p>\n\n\n\n
The Rosemount 935 uses infrared technology to detect highly combustible hydrocarbon gases including methane, propane and ethylene. The Rosemount 936 uses ultraviolet technology to detect hydrogen sulfide and ammonia, two of the most frequently seen toxic gases in industrial facilities. <\/p>\n\n\n\n
The latter, Emerson noted, leverages xenon flash technology to allow for greater installation flexibility compared with tunable diode laser (TDL) technology, which needs perfect alignment between beam and receiver.<\/p>\n\n\n\n
\u201cWith nearly twice the tolerance for misalignment than TDL, users can save up to 30% of installation time and streamline project schedules,\u201d the company noted.<\/p>\n\n\n\n
Conversely, open path detection technology uses a source and a detector, with the source sending modulated light beams across a monitored space, which the detector senses \u2013 specifically, the amount of light absorbed by the presence of gas. <\/p>\n\n\n\n
\u201cThis approach provides a high degree of coverage across wide areas up to 200 meters in length with accurate measurement, even if the toxic or combustible gas cloud is drifting at any point between the devices or when 95% of the light beam is obscured by fog, rain or smog. The system also will alert if the path is blocked completely by a physical obstruction,\u201d Emerson said.<\/p>\n\n\n\n
Both the Rosemount 935 and 936 can be used with Emerson\u2019s line of flame and gas detection products to create a comprehensive safety system.<\/p>\n","protected":false},"excerpt":{"rendered":"
