The SFY sets up in minutes with a free Windows® compatible Intelligent PC Configuration Software that lets users choose, and then view to confirm, all application specific operating parameters. The SFY also allows users to program a moving average filter which minimizes measurement instability caused by the effects of bent turbine blades or other frequency variations.
The unit is exida certified to IEC 61508:2010 for systematic integrity up to SIL 3 and for random integrity up to SIL 2. This means the SFY can be used for many safety applications because it is approved for single use in SIS up to SIL 2 and in a redundant architecture (1oo2, 2oo3, etc.) up to SIL 3. Comprehensive FMEDA certified safety data is available upon request allowing a functional safety practitioner to access the FMEDA data on the SFY to determine the SFY’s applicability in specific safety-related applications.
The SFY has an exceptional accuracy and long-term stability with a typical accuracy of ±0.025% of span and up to 5 years between scheduled calibrations. The SFY also has a user-configurable 5–digit LCD display that shows the process variable in selectable frequency units. The exida certified SFY is input-to-output isolated and RFI/EMI protected, making it resistant to unpredictable ground loops and the harmful effects of plant and equipment noise. It is also available in explosion-proof/flameproof housings for use in hazardous environments.
