Process Control and Instrumentation Normal mercury thermometer can be used to measure a temperature of about 300°C. However, its maximum temperature measurement range can be increased upto about 500°C by Filling nitrogen under pressure in the stem Increasing the diameter of the tube Accounting for the tube expansion Using steel tube in place of glass tube Filling nitrogen under pressure in the stem Increasing the diameter of the tube Accounting for the tube expansion Using steel tube in place of glass tube ANSWER DOWNLOAD EXAMIANS APP

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