SENSORS FOR SULFUR ACTIVITY MEASUREMENTS

摘要

A method and a sensor to measure the sulfur activity in sulfur-containing environments are disclosed. The active component is a non-stoichiometric metal sulfide foil or film (3). In the case of a thin sulfide film, a ceramic substrate (1) is employed for improved mechanical rigidity. The electrical conductivity of the sulfide is related to the sulfur activity of the process stream to which it is exposed.
