2. Gas detector - Wikipedia

   en.wikipedia.org/wiki/Gas_detector

   A gas detector can sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave. This type of device is important because there are many gases that can be harmful to organic life, such as humans or animals. Gas detectors can be used to detect combustible, flammable and toxic gases, and oxygen depletion.

3. Infrared open-path detector - Wikipedia

   en.wikipedia.org/wiki/Infrared_open-path_detector

   An open path detector usually costs more than a single point detector, so there is little incentive for applications that play to a point detector's strengths: where the point detector can be placed at the known location of the highest gas concentration, and a relatively slow response is acceptable. The open path detector excels in outdoor ...

   Delmarva Power has a 5,000-square-mile (13,000 km 2) service area located on the Delmarva Peninsula, serving much of the state of Delaware and the Eastern Shore region of Maryland. [1] The company provides electricity to 312,000 customers in Delaware and 203,000 customers in Maryland as well as natural gas to 129,000 customers in northern Delaware.

5. Catalytic bead sensor - Wikipedia

   en.wikipedia.org/wiki/Catalytic_bead_sensor

   Passing combustible gas raises the temperature further which increases the resistance of the platinum coil in the catalysed bead, leading to an imbalance of the bridge. This output change is linear, for most gases, up to and beyond 100% LEL , response time is a few seconds to detect alarm levels (around 20% LEL), [ 1 ] at least 12% oxygen by ...

7. Thermal conductivity detector - Wikipedia

   en.wikipedia.org/wiki/Thermal_conductivity_detector

   The thermal conductivity detector (TCD), also known as a katharometer, is a bulk property detector and a chemical specific detector commonly used in gas chromatography. [1] This detector senses changes in the thermal conductivity of the column eluent and compares it to a reference flow of carrier gas. Since most compounds have a thermal ...
