Honeywell Analytics supplies Infrared Detection Unit. Honeywell Analytics products are manufactured in accordance with UL 2034, BS 7860:1996, and EN-50291:2001 and ISO 9001:2000. The Infrared Detection Unit, Searchline Excel operates in potentially hazardous environments, detecting the presence and build up of explosive concentration of Hydrocarbon gas clouds. Searchline Excel is certified to Exd and has the major CENELEC and UL / CSA approvals for worldwide acceptance. The receiver unit produces an analog output signal proportional to actual gas concentrations within the volume of air located between transmitter and receiver. The signal indicates the level of potential hazard in units of LEL. Plant shutdown, staff evacuation or forced ventilation can be done as a direct result of Searchline Excel`s alarm warning, maintaining plant productivity as long and as safely as possible. Typically, Infrared Detection Unit operates over a recommended line of sight distance from 5m to 200m [15 to 650ft]. Systems are used in applications ranging from offshore platforms and vessels, downstream chemical processing plants, gas transport and pipelines, large storage areas and buildings at risk from the build up of volatile vapours.
