Case Studies

"I am extremely satisfied with the service and calibration packages. Turnaround is always fast and efficient and communications throughout the process are fantastic. I would not hesitate to recommend Shawcity, as I have already on many occasions."

Redline Plus XDI-F1-CA-IR Flammable Hydrocarbon (0-100% LEL)

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.


This information relates to the device operating continuously.
