The present range of CENTORK positioners offers the following basic features:
• Reliable : Excellent sensibility ,repetitivity and hysteresis performance.
• Strong : The pneumatic and electropneumatic version are resistant to the physical and chemical agents.
• Simple : Reduced number of parts. Enormous setting and maintenance simplicity.
THE FUNCTIONAL FEATURES ARE:
• Linearity : It shows the approach to the theoretical regulation that can be achieved, by positioner valve.
• Repetitivity : It reflects the difference in the response value, to a given control signal, when the set value is produced from any end of the control scale.
• Hysteresis : It is the maximum difference in the response value, for the same control signal, when the set value is produced from any end of the control scale.
• Sensitivity : It is the difference in the control signal in which the positioner valve reacts producing a response.
