Laser Falcon methane detector

Laser Falcon is sensitive only to methane, so no false readings of other gases are possible. It is a class 3R eye-safe laser.

The concept is based on Infrared Absorption Spectroscopy. The laser emits light (spectral range of 1,65 μm), which reflects back and is captured by the sensor. The outgoing and incoming signals are compared with the built-in reference cell. If methane is present along the laser path, the laser light is partially absorbed. An algorithm calculates the gas concentration in ppm×m (parts per million multiplied by meter). The value is instantly transferred to the remote control (RC) of the drone pilot and to UgCS software.

Can a methane detector detect other gases?

No, each device is designed to detect a specific gas. This provides a 100% probability of leak
detection of methane and not any other gas.

Is laser radiation hazardous for eyes?

Laser radiation is completely safe, it corresponds to class 1.

Can the remote laser detector be used at night, in rain, fog and snowfall?

Yes. It is an active device, it emits at a certain narrow wavelength, so it does not need additional
signal sources.

Do I need to calibrate detectors before commissioning?

No. The detector contains a reference container with methane inside and calibration is performed
at each start-up and during operation.

How often do detectors need to be verified?

The detector does not need to be verified because it is not a measuring tool.

Why is a laser detector better than a common sniffer?

It works remotely. There is no direct contact with the hazardous environment.

Can the detector detect methane through glass?

Yes, because glass transmits the near infrared radiation well.
