The AVID SmartCal-NB positioner feeds back accurate valve position without the need for linkages, levers and rotary or 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. The operating benefits of non-contact position feedback
are:
· Hysteresis: Non-existent
· Deadband: Non-existent
· Resolution: Infinite
· Repeatability: Exact
For use in Safety Related Nuclear Power Plant applications, in compliance with 10CFR50 Appendix B and 10CFR21.
