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 Increasing the diameter of the tube Filling nitrogen under pressure in the stem Using steel tube in place of glass tube Accounting for the tube expansion Increasing the diameter of the tube Filling nitrogen under pressure in the stem Using steel tube in place of glass tube Accounting for the tube expansion ANSWER DOWNLOAD EXAMIANS APP

Process Control and Instrumentation In a closed loop system, the process to be controlled is an integrating process with transfer function l/2s. The controller proposed to be used in an integral controller with transfer function 1/T₁s. When a step change in set point is applied to such a closed loop system, the controlled variable will exhibit Undamped response Underdamped response Overdamped response Unstable response Undamped response Underdamped response Overdamped response Unstable response ANSWER DOWNLOAD EXAMIANS APP
