The dynamic behavior of a temperature sensor / transmitter can be modeled as a first-order transfer function (in deviation variables) that relates the measured value T_mto the actual temperature, T

Both T_m and T€² have units of ^ˆ˜C and the time constant has units of seconds. An alarm will sound when T_m exceeds 30 ^ˆ˜C. If the process is initially at steady state, and then T suddenly changes from 25 to 35 ^ˆ˜C at 1:10 PM, at what time will the alarm sound?
