The GDS Red Line XDI sensor uses proven non-dispersive single beam dual-wave length infrared principles to detect and monitor the presence of gases. This non-poisoning sensing technique relies on the target gas having a unique well-defined absorption signature. This is used to identify the presence of the target gas and is highly specific. Using a suitable infrared source, an analysis of the optical absorption through the gas allows the concentration of the target gas to be determined. All sensor driving is internal to the transmitter and full fault monitoring of the sensor and transmitter is continuous.
The GDS XDI-F1 Red Line is an explosion proof infrared detector for flammable hydrocarbon gases in hazardous areas, certified to ATEX, IECEx and UKEX. It is the version without a local display: readings and alarms go to the control panel. If engineers need to read the gas level and adjust the detector at the head, the XDIwin-F1 is the version with a display, and we supply, install, commission and service both.
