Determination of the time behaviour of thermocouples for sensor speedup and medium supervision; pp. 295–309

Bernhard Sarnes, Elmar Schrüfer

Thermocouples can not only be used for temperature measurement, but also for supervising the surrounding medium. For both applications the knowledge of the thermocouple time constant is necessary. As the time constant changes with operational conditions, online calibration is needed. This aim has been achieved for metallic sheathed thermocouples by modelling and test measurements.
