Specifications
BeamSight is a remote gas analyzer for true standoff detection. It analyzes gas concentrations from a distance, with no contact with the gas, in a fixed or a battery-powered portable configuration.
The true remote configuration makes commissioning alignment-free, with no long cables and no complex mechanical or opto-mechanical constructions. A single system can monitor a large area and delivers measurement results at a safe distance from potentially hazardous gases.
BeamSight uses Tunable Diode Laser Absorption Spectroscopy (TDLAS) on the Beamonics proprietary remote TDLAS platform, and is inherently calibration-free and maintenance-free. Sensor poisoning does not affect the measurement, and BeamSight measures continuously from very low background atmospheric levels up to saturation at 100 vol%.
Sensitivity is high enough to analyze background atmospheric concentrations of several gases, such as CH₄ and CO₂. Target gases include CH₄, CO, CO₂, H₂S, HF, C₂H₂, NH₃ and HCl, and the precision for each under standard test conditions is listed under Examples of gases. BeamSight reports path-integrated concentration in ppm·m, because the path length is variable and unknown.
The fixed configuration suits permanent installations. The battery-powered configuration runs for 5 h and suits portable use, including rover- and drone-mounted setups. BeamSight is delivered integration-ready, with USB, UART and I²C interfaces.
