Параметр Analysis

Each option block in the 21505-68-96-05-02 part number defines one element of the hardware configuration, from mechanical dimensions to connector style and approval suffix. The unthreaded length Option specifies 68- 6.8in. The overall case length Option specifies 96- 9.6 in. The total length Option specifies 05- 0.5 metre (20 inches). The unit is rated for operation from Typically-396change in scale factor at + 150°F(+ 65°C) at 50 mils gap (1.27 mm).

Probe performance is specified together with the matching extension cable and Proximitor, so replacing the complete loop under consistent part numbers preserves the calibrated scale factor and linearity of the measurement chain.

Применение Scenarios

Typical duty for this probe is continuous shaft monitoring on critical rotating machinery, where it provides the raw vibration and position signals for alarm and trip logic in the associated monitoring rack.

Installation Guide

Thread the probe into its tapped hole, respect the thread engagement limits of the case, and mate the connector to the matching extension cable. Set the initial gap according to the electrical requirements of the associated Proximitor and verify the gap voltage against system documentation before returning the machine to service.

Compatibility

This component belongs to the 7200 series proximity system 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

Inspect the probe tip, threads, and cable jacket at each outage for wear or damage, and confirm connector seating and torque have not relaxed in service. Keep the unit within its Typically-396change in scale factor at + 150°F(+ 65°C) at 50 mils gap (1.27 mm) operating envelope in service and storage.

Procurement Advice

This unit is supplied new & original in factory packing with 12 months factory warranty. 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 Typically-396change in scale factor at + 150°F(+ 65°C) at 50 mils gap (1.27 mm), covering the temperature extremes typical of turbomachinery installations.

What connector or interface does it use?

It uses -With miniature male coaxial connector, 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.

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.
