· Thin-film sacrificial copper strips as sulfur corrosion sensors. The addition of elemental sulfur into insulating oils at varied concentrations produced varying corrosion settings. Fig. 5 shows that incremental change in elemental sulfur concentrations leads to increased loss of copper from glass substrate, hence modified the sensor surface morphology. After 1 h of aging at 90 °C in the ...
Sulfur compounds are ubiquitous in refining and petrochemical products • Variable in crude oils ranging from ppb level components to wt.% level S • Sweet vs. Sour Crude oil • Levels of sulfur in crude oil grow approximately 500 ppm per year, making sulfur management an ever increasing burden. Sulfur compounds create processing problems for refiners, natural gas, companies, and ...
Sulfur sensor for use on the high seas Ship emissions heavily pollute marine ecosystems and are extremely detrimental to the health of humans in harbor areas. Alongside carbon dioxide and nitrogen oxides, seagoing vessels primarily emit large quan-tities of sulfur oxides. A new photoacoustic sensor system has now been developed that is intended to enable continuous monitoring of maritime SO x ...
· The sulfur sensor overcame the defect that sulfide was easy to oxidize as auxiliary electrode, and obviously simplified the manufacturing process. The processing cost was greatly reduced and the sensor could be kept for a long time without any special protection, which created a necessary condition for industrial application.
· The gas sensor can detect Volatile Organic Compounds (VOCs), volatile sulfur compounds (VSCs) and other gases such as carbon monoxide and hydrogen in the part per billion (ppb) range. Additionally to all features of the BME680, the BME688 has a gas scanner function. In standard configuration, the presence of VSCs is being detected as indicator ...
· The paper reports the development of high temperature in situ fully solid electrochemical sensor for sulfur-containing gases monitoring. The sensor is based on Ag+β”-Al2O3 membrane with Ag2S or Ag2SO4 layer on its surface. Silver beta alumina was manufactured by high temperature ion exchange technique in AgNO3 melt. The original design of the in situ sensor was developed.
Abstract A novel electrochemical sulfur sensor using Laβ-Al 2 O 3 as solid electrolyte and La 2 O 2 S+La 2 O 3 as auxiliary electrode material has been developed. It can be applied not only in molten iron but in molten steel as well, where the oxygen concentration is in the range from to ppm, because a more stable auxiliary material of La 2 O 2 S was used in the sensor.

ME4-SO2 sulfur dioxide gas sensor is constant potential electrolysis type. Oxidation-reduction reaction with sulfur dioxide and oxygen take place respectively on the working electrode and on the counter electrode. The process releases electric charge and generates current. The current is in direct proportion to the concentration of sulfur dioxide.

· A sulphur dioxide gas detector is composed of electronics and an SO2 sensor. The gas sensor converts the detected gas concentration to an electronic signal for analysis by the onboard microprocessor. After receiving the electrical signal, the processor displays the SO2 concentration reading. If the measurement exceeds the pre-set SO2 alarm value, the alarms are triggered.
