FAQ
Frequently Asked Questions (FAQ)
Q1: What is the function of the Bently Nevada 3500/25 Enhanced Keyphasor Module?
A1: It generates digital Keyphasor signals from proximity probes or magnetic pickups, used to synchronize vibration data with shaft rotation.
Q2: How many Keyphasor signals can a single module handle?
A2: Each module supports two channels. The system can support up to 4 signals in standard configuration, or up to 8 in a paired configuration.
Q3: Can this module be used in Triple Modular Redundant (TMR) applications?
A3: Yes, two modules are used in parallel to provide both primary and secondary Keyphasor signals for TMR systems.
Q4: What’s the minimum speed requirement for magnetic pickup signals?
A4: The minimum rotative speed required is greater than 200 rpm for magnetic pickup operation.
Q5: Is the Enhanced Keyphasor Module compatible with older Keyphasor systems?
A5: Yes, it is fully backward compatible in form, fit, and function with the previous Keyphasor modules (e.g., 125792-01).
Q6: What are the output options for buffered Keyphasor signals?
A6: Buffered signals are available via two front coaxial connectors and two rear Euro Style connectors.
Q7: What are the key differences between isolated and non-isolated I/O modules?
A7: Isolated I/O modules offer galvanic isolation and are preferred in magnetic pickup applications; however, they introduce more phase shift compared to non-isolated versions.
Q8: Does this module support field upgrades?
A8: Yes, it features field-upgradeable firmware and supports asset management data reporting for improved maintainability.
