Sacrificial copper strip sensors for sulfur corrosion ...

· 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 ...

An application of the electrochemical sulfur sensor in ...

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--Winsen

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.

Best Sulphur Dioxide (SO2) Gas Detector (Top Pick ...

· 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.
