Special Issue Information

Dear Colleagues,

Photoacoustic spectroscopy (PAS) combines the advantages of high sensitivity, high specificity and having a zero background, which is very suitable for trace gas detection. This Special Issue of the journal Sensors, entitled “Photoacoustic Sensors and Devices for Gas Detection”, will focus on all aspects of research and development related to these areas.

Papers which focus on the simulation, design and experimental verification of photoacoustic sensors as well as papers which focus on the results of sensor field testing in these areas are welcome. It is the goal of this Special Issue to provide a broad platform for publishing the many rapid advances which are currently being achieved in photoacoustic gas sensing technology.

The list of topics of interest includes (but is not limited to) the following:

  • Photoacoustic excitation light sources;
  • Design and verification of novel photoacoustic cells;
  • Detection of weak photoacoustic signals;
  • Signal processing methods;
  • Noise cancellation techniques;
  • Miniaturization of photoacoustic sensors and devices;
  • Calibration and inspection of photoacoustic sensors;
  • Application of photoacoustic sensors and devices in the field.

Internal discharge and overheating faults in sulfur hexafluoride (SF6) gas-insulated electrical equipment will generate a series of characteristic gas products. Hydrogen fluoride (HF) is one of the main decomposition gases under discharge failure. Because of its extremely corrosive nature, it can react with other materials in gas-insulated switchgear (GIS), resulting in a short existence time, so it needs to be detected online. Resonant gas photoacoustic spectroscopy has the advantage of high sensitivity, fast response, and no sample gas consumption, and can be used for the online detection of flowing gas. In this paper, a simulated GIS corona discharge experimental platform was built, and the HF generated in the discharge was detected online by gas photoacoustic spectroscopy. The absorption peak of HF molecule near 1312.59 nm was selected as the absorption spectral line, and a resonant photoacoustic cell was designed. To improve the detection sensitivity of HF, wavelength modulation and second-harmonic detection technology were used. The online monitoring of HF in the simulated GIS corona discharge fault was successfully realized. The experimental results show that the sensitivity of the designed photoacoustic spectroscopy detection system for HF is 0.445 μV/(μL/L), and the limit of detection (LOD) is 0.611 μL/L. Full article
