Product Overview

The Bently Nevada 31000-16-10-00-050-03-02 stands as a cornerstone in high-reliability turbine supervisory instrumentation (TSI). This precision-engineered Proximity Probe Housing Assembly facilitates the external mounting of 3300 XL 8 mm proximity probes, essential for monitoring radial vibration and capturing critical Keyphasor phase references. Designed to withstand the rigors of heavy industrial environments, this assembly allows maintenance teams to adjust probe gaps or replace sensors without the costly necessity of a machine shutdown. By providing a stable, pressure-sealed interface, it ensures that your vibration monitoring system receives clean, uninterrupted signals from the rotor surface. Its full compliance with API 670 standards guarantees that it meets the most stringent global requirements for mechanical configuration and operational safety in oil, gas, and power generation sectors.

Model Option Breakdown

The 31000 series utilizes a specific suffix logic to tailor the hardware to the machine casing. The configuration for 31000-16-10-00-050-03-02 is decoded as follows:

• -16 (Unthreaded Standoff): 1.6-inch unthreaded length, providing the necessary clearance for the probe leads and connector.

• -10 (Overall Standoff Length): 1.0-inch total length for the standoff adapter.

• -00 (Probe Penetration): 0.0 inches (standard depth configuration).

• -050 (Fittings Option): Equipped with 1/2-14 NPT explosion-proof fittings, ensuring hazardous area compliance.

• -03 (Mounting Thread): 3/4-14 NPT threads for secure attachment to the machine housing.

• -02 (Probe Option): Pre-configured for use with 3300 XL 8 mm proximity probes.

Vital Statistics

Field Installation Protocol

Successful deployment requires strict adherence to mechanical clearances. Engineers must ensure the probe tip remains perfectly perpendicular to the target shaft to prevent signal distortion. When installing the 31000-16-10-00-050-03-02, apply a high-quality thread sealant to the NPT connections to maintain casing pressure integrity. The internal probe should be gapped using a calibrated voltmeter to reach the standard -10.0 Vdc (linear mid-point) before final tightening. Ensure the extension cable's minimum bend radius is maintained within the housing to prevent premature signal degradation or physical conductor failure.

Operational Superiority

The primary advantage of the 31000 series lies in its "Online Accessibility." Traditional internal mounting requires a full machine stop for even minor adjustments; however, this housing permits real-time maintenance. Its robust seals prevent oil leaks and atmospheric contamination, protecting the sensitive 3300 XL probe from the harsh internal environment of steam turbines or centrifugal compressors. Furthermore, the standardized mounting threads and explosion-proof fittings make it a "drop-in" solution for plants moving toward API 670 compliance, ensuring seamless integration with Bently Nevada 3500 rack systems.

Expert Technical Inquiry

Q1: Can I use this housing for a 5mm probe instead of the 8mm?

A1: The -02 option in this specific model (31000-16-10-00-050-03-02) is machined specifically for the 3300 XL 8 mm probe. Using a 5mm probe would require a different internal sleeve and adapter to ensure proper alignment and thread engagement.

Q2: Does this assembly include the proximity probe itself?

A2: No, the 31000 series is the housing assembly only. The 3300 XL 8 mm probe and extension cable must be ordered separately, although this housing is designed to perfectly accommodate them.

Q3: Is the housing explosion-proof?

A3: Yes, the -050 option specifies fittings that meet NEMA 4 and explosion-proof requirements, making it suitable for Class I, Division 1 hazardous areas when installed per local electrical codes.
