Process Control and Instrumentation The characteristic equation for the control system with a closed loop transfer function G₁/1 + G₂ is given by 1 + G₂ = 0. The characteristic equation for the control system Depends only upon the open loop transfer function All of these Determines its stability Is the same for set point or load changes Depends only upon the open loop transfer function All of these Determines its stability Is the same for set point or load changes 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 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 Both B and C Here ANSWER DOWNLOAD EXAMIANS APP
