  2. Hydrogen sensor - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_sensor

    A hydrogen sensor is a gas detector that detects the presence of hydrogen. They contain micro-fabricated point-contact hydrogen sensors and are used to locate hydrogen leaks. They are considered low-cost, compact, durable, and easy to maintain as compared to conventional gas detecting instruments. [1]

  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 ...

  4. Gaseous detection device - Wikipedia

    en.wikipedia.org/wiki/Gaseous_detection_device

    The gaseous detection device (GDD) is a method and apparatus for the detection of signals in the gaseous environment of an environmental scanning electron microscope (ESEM) and all scanned beam type of instruments that allow a minimum gas pressure for the detector to operate.

  5. Nondispersive infrared sensor - Wikipedia

    en.wikipedia.org/wiki/Nondispersive_infrared_sensor

    A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas detector.It is non-dispersive in the fact that no dispersive element (e.g a prism or diffraction grating as is often present in other spectrometers) is used to separate out (like a monochromator) the broadband light into a narrow spectrum suitable for gas sensing.

  6. Photoionization detector - Wikipedia

    en.wikipedia.org/wiki/Photoionization_detector

    The photoionization detector is an efficient and inexpensive detector for many gas and vapor analytes. PIDs produce instantaneous readings, operate continuously, and are commonly used as detectors for gas chromatography or as hand-held portable instruments. Hand-held, battery-operated versions are widely used in military, industrial, and ...

  7. Instrumentation in petrochemical industries - Wikipedia

    en.wikipedia.org/wiki/Instrumentation_in...

    The fire and gas detection system comprises local sensors to detect the presence of gas, smoke or fire. These initiate alarms in the control room. Simultaneous detection of multiple sensors initiates action to start firewater pumps and close fire dampers in enclosed spaces. The petrochemical plant may have several levels of shutdown.
