Festo recently introduced the CMSH smart positioner for process valves. This new smart device features HART communication. Because of its high airflow rate, the CMSH is suitable for both large and small actuators in such applications as dosing, mixing and filling. The CMSH offers extensive integrated functions for self-monitoring and diagnostics with clear recommendations for corrective action. The CMSH is user-friendly and simple to operate because of its large and rotatable plain-text display that can be read from various directions. The setup wizard makes it easy to commission. As part of this process, fast or robust control mode can be selected.
