1.4 Principle of Operation
Unlike conventional positioners, the ICoT Smart Positioner feeds back valve
position without the need for linkages, levers, or rotary and linear seals.
Position sensing is performed totally by non-contacting means, permitting use
of advanced control strategies where knowledge of valve position is used in
predictive and other algorithms. By the integration of multiple components into
a singular, cost efficient unit, microprocessor-based intelligence can now be
used to implement advanced functions such as early warning diagnostics and
fugitive emissions monitoring.
The ICoT positioner provides intelligence for the control valve through a
microprocessor-based diagnostic system utilizing HART
®
or Foundation
Fieldbus protocols. Accurate measurement of valve stem position, input
signal, actuator pressure and travel time can be recorded during normal
operation, thereby providing information for control valve signature
generation.
