This study revisits the design of resistance wire thermometers (RWTs) for measuring time-resolved temperature pulsations of the exhaust gas on internal combustion engines. RWTs with gold coated tungsten wires were fabricated and tested on a heavy-duty diesel engine. Experimental results indi-cate their utility in such harsh environments with the addition of a protective ceramic coating over the welded joints. The influence of the coating on sensor geometry and response will be elucidated through shock tube and gas stand experiments.
