Product Details
The Bently Nevada 1701/15, also cataloged as the 1701/15 FieldMonitor Proximitor Input Monitor, operates as a dedicated hardware component for 2-channel radial vibration and thrust position conditioning within Bently Nevada FieldMonitor systems. It accepts raw signals from eddy current proximity probes, processes them into engineering units, and evaluates measured values against programmable alarm setpoints.

Eddy-Current Probe Scaling and Gap Voltage Validation
The Bently Nevada 1701/15 executes precise eddy-current probe scaling to ensure accurate measurement across radial vibration and axial thrust channels. Proper transducer integration depends on gap voltage validation (-10 VDC targets for nominal center bias) performed at the input terminals before alarm thresholds are configured. Correct voltage setting guarantees optimum dynamic linear response across rotor dynamics tracking cycles, eliminating signal saturation and ensuring high cross-talk suppression between adjacent monitoring channels.
Frequently Asked Questions
Q: How does the internal self-test routine report fault conditions on the 1701/15 module?
A: Embedded diagnostic self-tests continuously check the internal circuit integrity and connected transducer loops, asserting a NOT OK status output when open circuits, short circuits, or hardware failures are detected.
Q: What power input parameters are required to drive the 1701/15 Proximitor Input Monitor?
A: The module operates from a nominal regulated supply voltage of 24 VDC while drawing a typical operational current of 100 mA.
Q: Can both channels be configured independently for different measurement tasks?
A: Yes, the 2-channel architecture allows user-programmable configuration for processing either dynamic radial vibration signals or axial thrust displacement inputs simultaneously.
Field Installation Guidelines
- Mount the 1701/15 module into its designated slot within the FieldMonitor enclosure, ensuring proper alignment with the backplane connectors before fully seating.
- Route incoming proximity probe field wiring using twisted-shielded cable pairs, keeping signal runs separated from high-voltage AC lines.
- Perform gap voltage validation on all connected eddy current probes to verify the static bias voltage matches factory specifications (-10 VDC target area) prior to machine startup.
- Connect cable shields to the designated system instrumentation earth ground at the cabinet entry point to prevent ground loops.
