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
