Multi-Loop Controllers are typically used for controlling multiple single Loops or interdependent loops. These controllers are also capable of small machine control with advanced features and options. Suitable for measure and control process parameters like temperature, humidity, carbon potential, pressure and flow. It also optionally incorporates special calculation/calibration blocks like Relative humidity, dew point, carbon potential, process profiling facility and digital communication.
