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 Rusting of iron takes place Embrittlement of iron occurs Both B and C Here Emf produced is very low of the order of microvolt Rusting of iron takes place Embrittlement of iron occurs Both B and C Here ANSWER DOWNLOAD EXAMIANS APP
