Toxic Gas & Oxygen Detectors | Gas Sensors | RC Systems

A sensor inside the toxic gas detector reads the gas levels, and when they rise above or fall below the specified level, an alarm activates. Sensors are made from electrochemical cells, and the alarm can be visual or audible. Readings can be sent via a digital signal or analog signal to a control room, and alarms can actuate local relays for the operation of alarm safety devices such as horns ...

Surface data sensors during drilling - PetroWiki - Oil&Gas

2015-06-26· The gas-detection sensors consist mainly of a gas trap, a pneumatic line linking the gas trap to the gas-detection equipment (which is found inside a mud-logging unit), and the gas-detection instruments (chromatograph and total-gas detectors). The gas trap is basically a floating chamber with a rotating “agitator” inside. It works on the principle that mud flowing through the gas trap is ...
