Infrared Open Path Gas Detector / SafEye Quasar 900
Quasar 900 is totally immune to interference from sunlight or any other sources of radiation such as flare stacks, arc welding or lightning.
The high power xenon lamp will compensate for changing weather conditions, including rain, fog, mist, snow and makes it immune to influences from solar radiation, arc-welding, stack flares or vibration from machinery.
Quasar 900 is approved to SIL2 (IEC61508), equipped with heated optics and tolerates a very wide temperature range to provide reliable detection.
No unrevealed failures. In normal operation, the output signal is 4 to 20 mA, depending on the measured gas concentration.
Sub-4mA signals includes indications for beam blockage (2mA), a fault (1mA) In addition
