BENTLY NEVADA 1701/15 1034549-20 141379-01 Input Monitor

The Bently Nevada 141379-01, also cataloged as the 1701/15 FieldMonitor Proximitor Input Monitor, operates as a dedicated hardware component for radial vibration and thrust position signal conditioning within rotating machinery protection systems.

Hardware Specifications

Gap Voltage Validation & Rotor Dynamics

The 141379-01 monitor conditions high-frequency transducer signals to evaluate continuous rotor dynamics across fluid-film bearings. Internal processing circuitry incorporates precise eddy-current probe scaling to convert dynamic gap variations into calibrated vibration and position metrics. Initial field configuration relies on gap voltage validation to establish nominal -10 VDC targets at the center of the probe's linear range. Active cross-talk suppression prevents signal interference between adjacent monitoring channels, ensuring reliable alarm output activation when shaft displacement exceeds preconfigured thresholds.

Frequently Asked Questions

Q: What primary measurement parameters does the 141379-01 monitor evaluate?

A: The module conditions proximity probe inputs across 2 independent channels to measure dynamic radial vibration and static shaft thrust position.

Q: What input power is required to operate the 1701/15 monitor?

A: The module requires a regulated continuous supply voltage of 24 VDC.

Field Installation Guidelines

• Mount the FieldMonitor module securely into its designated enclosure slot, verifying that backplane guide pins align properly prior to seating.
• Land proximity probe field wiring on the transducer I/O terminals, ensuring cable shields are grounded at a single chassis point to prevent ground loops.
• Perform gap voltage validation using a calibrated multimeter to verify the transducer rests near the nominal -10 VDC bias point at idle.
• Route all low-level signal cables in grounded metal conduits separated from high-voltage AC lines by a minimum of 300 mm.
