SafEye Xenon 700 Open-path Gas Detection System
Brand: OldhamThe SafEye Xenon 700 consists of an advanced Xenon Flash infrared transmitter (source) and infrared detector (receiver), separated over a line of sight from 13 feet (4 meters) up to 460 feet (140 meters) to detect and quantity flammable gas presence, even when challenged by extremely harsh environments where dust, fog, rain, snow, or vibration can cause a high reduction of signal.
The open path analyzes atmospheric absorption at three selected spectral bands, two in a region where the target gas absorbs and one where it does not absorb.
The ratio between these absorption lines can provide accurate information of the gas concentration along an optical path.
