Process Control and Instrumentation Temperature measurement range of iron-constantan thermocouple is 0 to 870°C. It can be used to measure sub zero temperature, because at lower temperature Emf produced is very low of the order of microvolt Both B and C Here Embrittlement of iron occurs Rusting of iron takes place Emf produced is very low of the order of microvolt Both B and C Here Embrittlement of iron occurs Rusting of iron takes place ANSWER DOWNLOAD EXAMIANS APP
