SEC - Millenium Infrared Gas Detector - Brochure

Operation / DescriptionSEC Millenium is a complete self contained optical hydrocarbon gas detector. The sensing and reference elements are self-compensating for optical integrity and other signal inhibitors. The industrystandard 4 - 20 mA analog output provides remote alarm, fault and calibration signals.ApplicationsThe SEC Millenium hydrocarbon detectors are designed to be used as an upgrade in the sameapplications where catalytic bead sensors have been applied.- Refineries - Gas turbines- Drilling and production platforms - Chemical plants- Fuel loading facilities - Compressor stations- Oil well logging - Wastewater treatment facilities- LNG/LPG processing and storage facilities - Transportation facilitiesFeatures  Reliable infrared sensing technology Virtually maintenance free Low cost of ownership, over five years operating life Immune to poisoning and etching Designed for harsh environments Explosion proof Rugged stainless steel construction Fast response time Smart calibration Patented self-compensating optics No moving parts Heated optical chamber Low power consumption Operates in constant hydrocarbon background Operates in anaerobic atmospheres Fault indications for all failure states Routine calibrations are not required 4 to 20 mA output 0 to 100% LFL detection range Can be coupled with SEC 3100 transmitter for network applications RS-485 communication link available Digital Display option availableSEC MilleniumInfrared HydrocarbonGas Detector© 09/11CSA Performance ApprovedSpecificationsModel: Sensor Electronics CorporationSEC MILLENIUM Infrared Hydrocarbon Gas DetectorAvailable gases: Propane PropyleneMethane n-Butane EthaneGasoline Ethanol Isopropyl Alcohol Ethylene Methanol Aeromatic 150Pentane Hexane CyclopentaneIsobutane Methyl Amyl KetonePlease note that this list is not all-inclusive.
