Description

Description

The SEC 5000 IREvolution hydrocarbon detector is a rugged reliable microprocessor based intelligent infrared gas detector for monitoring hydrocarbons

The SEC 5000 IREvolution is ideally suited for use in harsh environments and where the costs of required maintenance for conventional catalytic or electrochemical detectors are prohibitive.  The SEC 5000 IREvolution Infrared gas detector will perform reliably in the presence of silicone and other catalytic poisoning agents and can also operate in oxygen free environments or where high background gas levels are present.  There are no known poisons that affect this technology.

The SEC 5000 IREvolution is a stand-alone device providing a linear continuous 4 to 20 mA output representing 0 to Full Scale.  The SEC 5000 IREvolution can operate as a stand-alone or can be coupled with the SEC 3100 Universal Transmitter, 3120 Dual Transmitter, 3100 DIN Controller or 3120 DIN Controller.

The SEC 5000 also provides a one-wire interactive digital interface and an optional HART Interface.

 

Features

  • Requires no routine calibration to ensure proper operation
  • Continuous self-test automatically indicates a fault, with fail to safe operation
  • A multi-layered filtering system protects optics from dirt and water ingress
  • Straight optical path eliminates the need for reflective surfaces, such as mirrors or beam splitters
  • Performs well in the presence of high concentrations or constant background levels of hydrocarbons and in oxygen depleted atmospheres
  • Highly resistant to poisoning and etching
  • Standard 4 to 20 mA output (current source)
  • Explosion proof housing designed for harsh environments
  • Smart Calibration AutoACTM circuit

Applications

  • Refineries, process applications
  • Drilling and production platforms
  • Fuel loading facilities
  • Oil well logging
  • LNG/LPG processing and storage facilities
  • Gas turbines
  • Chemical plants
  • Compressor stations
  • Wastewater treatment facilities
  • Transportation facilities.
