Parameter Analysis

The ordering string of the 74712-06-05-04-01 encodes its physical and electrical configuration, so every digit should be checked against the machine drawing before substitution. The transducer mounting angle/minimum operating frequency Option specifies 06 = 0 ±100, 10 Hz (600 cpm). The mounting base Option specifies 05 = No base; 1/2-in 20 UNF-3A stud. The connector Option specifies 04 = Side mount. The unit is rated for operation from -29°C to +204°C (-20°F to +400°F). Compliance documentation covers cSA.

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. Keep the unit within its -29°C to +204°C (-20°F to +400°F) operating envelope in service and storage.

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

What is the operating temperature range?

The unit is rated from -29°C to +204°C (-20°F to +400°F), covering the temperature extremes typical of turbomachinery installations.

What approvals or certifications does it carry?

Compliance documentation covers cSA. Confirm the approval suffix on your part number before ordering for hazardous-area use.

What connector or interface does it use?

It uses side mount, matching the standard Bently Nevada measurement chain.

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.
