IR Open Path Gas Detector – GD10L

 

simtronics2

The GD10L provides an effective response to the detection of gas hazards in a wide range of industrial environments from boiler plant room to offshore petrochemical installations. The unit combines a transmitter/ receiver into a single housing and utilise a novel retro-reflector. The whole system can be commissionable by a single person.

  • Life-time Stability
    The SimSource infrared light source is a solid-state component with a stable output and 60years of expected lifetime. This, together with the Simtronics IR-path design gives you a detector with unparalleled stability.
  • Easy Installation
    As the detector has a combined transmitter and receiver, alignment and commissioning may be done by a single technician.
  • Low Maintenance Costs
    GD10L requires no regular field maintenance, apart from cleaning the optics. It has a fixed factory calibration, and is not recalibrated during its lifetime.
  • FPSO
    The rough environment on FPSOs with vibrations and movement, is a typical area where you need offshore quality on brackets and housings. GD10L has both.
  • Petrochemical and general industry
    The easy handling and low maintenance makes the GD10L well suited for general section separation in industrial plants outdoor and indoor.
