Description

The Bently Nevada 1034549-20, also cataloged as the 1034549-20 Proximitor Input Modules, operates as a dedicated hardware component for dual-channel radial vibration, axial displacement, and shaft centerline position measurement within FieldMonitor 1701/15 and 3500 series racks.

Hardware Specifications

Eddy-Current Probe Scaling and Gap Voltage Validation

The Bently Nevada 1034549-20 processes raw high-frequency signals received from connected proximity probes via dedicated hardware signal conditioning circuits. Internal scaling stages convert field voltages to reflect exact mechanical displacements, ensuring accurate eddy-current probe scaling across dynamic monitoring ranges. Continuous gap voltage validation maintains probe bias within target limits (such as -10 VDC targets), guaranteeing proper transducer alignment and protecting rotor dynamics tracking from signal saturation or baseline drift.

Frequently Asked Questions

Q: What sensor types connect directly to the two input channels on the 1034549-20 module?

A: The module accepts direct inputs from two Bently Nevada Proximitor eddy-current probe systems to measure dynamic radial shaft vibration, axial position, or centerline position.

Q: How is operating power supplied to the 1034549-20 Proximitor Input Module?

A: Power is drawn directly from the internal backplane bus of the host rack assembly (such as FieldMonitor 1701/15 or 3500 series chassis), eliminating the need for external module power connections.

Field Installation Guidelines

• First, inspect the module slot inside the host rack assembly to ensure connectors and guide rails are free of physical debris.
• Next, align the card edges of the 1034549-20 module with the guide channels and slide the unit inward until the backplane connector engages fully.
• Additionally, secure the module in the chassis frame by tightening the top and bottom front-panel retaining screws.
• Finally, connect field wiring from the Proximitor sensors to the designated rear terminal block, ensuring proper shield termination at the system ground point.
