Open path flammable gas detection using differential infrared absorption has been available for many years.
The introduction of Tuneable Laser Diode (TLD) generated, single wavelength, infrared detection enables target gas specific detection with no cross interference from other hydrocarbons.
These laser-based devices provide greater sensitivity and improved uptime availability in poor weather conditions than the traditional differential IR devices.
They are also available for target gas specific detection of toxic gases and employ an automatic, daily, self-test facility that removes the need for routine manual testing.
This presentation will outline the pros and cons of this technology in comparison to other gas sensing technologies.
