The process controller / temperature controller PCE-C 91 is a very compact PID controller measuring 48 x 48 mm / 1.9 x 1.9" (1/16 DIN). To make safe and fast control possible, the temperature controller is equipped with a fuzzy controller. This changes the PID parameters in the temperature controller so that setpoints can be reached quickly but with little overshoot. Thanks to a measuring rate of 5 Hz, this temperature controller can also be used in fast processes.
