Based on this error, the controller sends an actuating signal to the heating coil, which adjusts the temperature accordingly. The difference between the measured signal and set point is the error. The measurement signal is then compared to the set point, or desired temperature setting, of the controller. This measurement produces a measurement signal. A temperature sensor first measures the temperature of the fluid. \): Temperature controller in a CSTRĪs shown in Figure 1, the temperature controller controls the temperature of a fluid within a CSTR (Continuous Stirred Tank Reactor).
