SULFUR COMPONENT SENSOR AND SULFUR COMPONENT DETECTOR

摘要

A sulfur-detecting sensor for detecting an integrated amount of hydrogen sulfide present in a gas stream passed over the sensor, characterized in that the sensor comprises a member formed of a material which is stable to hydrogen sulfide, and having a contacting side which is brought into contact with hydrogen sulfide, and a measuring member located on the contacting side of the former member, the measuring member being formed of a material which reacts with hydrogen sulfide to yield a reaction product having an increased electrical resistance value and/or making a phase change into a phase easily scattered by the gas stream at a temperature of the vicinity of the contacting side, and allowing an integrated amount of hydrogen sulfide passed over the sensor to be measured by measuring its electrical resistance value. A sulfur-detecting device using the detecting sensor is also disclosed.
