  • Description


GD10PE – IR extended point Gas detector

GD10PE is the solution for ducts where conventional line detectors does not fit properly and standard point detectors are too slow. GD10PE is designed to meet the evolving safety norms for gas turbines, but is equally suited for HVAC and other applications where fast, low level and reliable detection is required.

High sensitivity, fast response

GD10PE has both, and is still protected against false alarms.

Life-time stability

The SimSource infrared light source is a solid-state component with a stable output and 60years of expected lifteime. This, together with the Simrad Optonics IR-path design gives you a detector with unparallelled stability.

No poisioning or saturation
  • Immune to silicon vapours, H2S and other widely used agents.
  • High gas concentrations will not saturate the detector.
  • Can be used to detect gases where oxygen is not present, e.g. in sub-sea production units
Low maintenance costs

GD10PE requires no regular field maintenance, apart from cleaning the optics. It has a fixed factory calibration, and is not recalibrated during its lifetime.
