Parameter Analysis

Each option block in the 3500/42M 140734-02 part number defines one element of the hardware configuration, from mechanical dimensions to connector style and approval suffix.

Sensor output is specified together with the associated monitoring machinery, so consistent part numbers across the loop keep sensitivity and linearity within their documented limits.

Application Scenarios

Installed on machine trains in power generation and process industries, this sensor feeds casing-level vibration data to the protection system for early fault detection.

Installation Guide

Mount the sensor at the documented location on the machine casing, torque the stud to specification, and route the cable to the monitor with correct shielding. Confirm the measurement channel responds before returning the train to operation.

Compatibility

This component belongs to the 3500 series monitoring rack and is engineered to work with the associated probes, extension cables, Proximitors, and monitoring hardware of the same system. Bently Nevada components sharing the same part number are fully interchangeable, so a stocked spare can be fitted without re-engineering the measurement loop. TenBN can supply the complete chain under consistent part numbers.

Maintenance Advice

Check the sensor mounting, cable, and connector condition during outages, and verify the measurement channel still responds to a known input.

Procurement Advice

Confirm the complete part number against your machine’s bill of materials before ordering, since each option digit changes the mechanical or electrical fit. TenBN stocks genuine Bently Nevada components and provides the official service documentation for this model.

Frequently Asked Questions

Can this spare be interchanged with existing components?

Bently Nevada components sharing the same part number are fully interchangeable, so this spare can replace an existing unit without recalibrating the loop when the complete part number matches.

How do I confirm the right part number?

Check every option digit against the machine bill of materials, then contact [email protected] with the full string; the TenBN team will confirm fit, stock, and documentation.
