Process Control and Instrumentation Suppose that the gain, time constant and dead time of a process with the following transfer function:Gc(s) = 10 exp( - 0.1s)/(0.5s + 1) are known with a possible error of ± 20% of their values. The largest permissible gain Kc of a proportional controller needs to be calculated below taking the values of process gain, time constant and dead time as 12, 0.4, 0.08 12, 0.6, 0.12 8, 0.6, 0.12 8, 0.6, 0.08 12, 0.4, 0.08 12, 0.6, 0.12 8, 0.6, 0.12 8, 0.6, 0.08 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 Embrittlement of iron occurs Emf produced is very low of the order of microvolt Rusting of iron takes place Both B and C Here Embrittlement of iron occurs Emf produced is very low of the order of microvolt Rusting of iron takes place Both B and C Here ANSWER DOWNLOAD EXAMIANS APP
