NDIR so2 Storage Systems for gas-insulated switchgears

Non-dispersive infrared (NDIR) is a physical sensing technique that provides a number of advantages over catalytic gas sensing method. The main feature of this technique is that fixed narrow-band filters are utilized with separate IR detectors to detect a few gas absorption lines across a restricted wavelength range.

  • Complete Gas Sensor Circuit Using Nondispersive Infrared (NDIR)

    Nondispersive infrared (NDIR) spectroscopy is often used to detect gas and measure the concentration of carbon oxides (for example, carbon monoxide and carbon dioxide). An infrared beam passes through the sampling chamber, and each gas component in the sample absorbs some particular frequency of infrared. By measuring the amount of absorbed infrared at the appropriate frequency, the concentration of the gas component can be determined.

    Carbon dioxide (CO 2 Breakers that use carbon dioxide as the insulating and arc extinguishing medium work on the same principles as a sulfur hexafluoride (SF 6 ) breaker. Because SF 6 is a greenhouse gas more potent than CO 2 , by switching from SF 6 to CO 2 it is possible to reduce the greenhouse gas emissions by 10 tons during the product lifecycle.
