Product Overview

The Bently Nevada 31000-28-10-00-015-03-02 represents the industry standard for protecting proximity probes in high-demand industrial environments. This Proximity Probe Housing Assembly facilitates precise sensor positioning while shielding the sensitive transducer from harsh external conditions such as oil, moisture, and mechanical impact. Specifically engineered for use with the 3300 XL 8mm Proximity Transducer System, this housing ensures that gap voltage remains stable and signal integrity is preserved during continuous operation.

In critical Turbine Supervisory Instrumentation (TSI) applications, the 31000 series provides a robust mechanical interface for radial vibration and axial thrust measurements. By allowing for external probe adjustment without machine disassembly, it significantly reduces maintenance downtime and improves personnel safety. This assembly is a vital component for ensuring the longevity of monitoring systems integrated with Bently Nevada 3500 rack architectures.

Part Number Breakdown and Suffix Logic

31000 Exploded Configuration

The specific alphanumeric string defines the mechanical dimensions and certification standards required for site-specific integration.

-28 (Probe Thread): Indicates a M10 x 1.0 metric thread configuration for compatibility with standard metric probe bodies.

-10 (Unused/Standard): Denotes a specific housing length of 1.0 inches for the internal probe sleeve.

-00 (Explosion Protection): Standard non-hazardous or base certification rating suitable for general industrial use.

-015 (Overall Length): Specified length of 1.5 inches for the sleeve assembly, ensuring the probe tip reaches the target surface accurately.

-03 (Housing Material): Constructed from 303 stainless steel, providing superior corrosion resistance in petrochemical and power generation environments.

-02 (Mounting Option): Standard 3/4-14 NPT conduit connection for seamless integration with rigid or flexible industrial conduits.

Technical Specifications

Field Installation Protocol

Engineering teams must verify the Probe Gap Voltage before final torque is applied. The housing allows the probe to be moved toward the target until the desired DC voltage (typically -10V for 3300 XL systems) is achieved on the proximitor output. Ensure the conduit entries are sealed with appropriate thread sealant to prevent internal moisture accumulation, which can cause signal drift or "ground loops." Always maintain a minimum cable bend radius of 25.4mm (1 inch) within the junction area to prevent coaxial core fatigue.

Performance Advantages

The 31000-28-10-00-015-03-02 housing is built for survival. Its stainless steel construction provides an impenetrable barrier against the caustic atmospheres found in oil and gas refineries. Unlike basic mounting brackets, this assembly offers a sealed environment that prevents process contaminants from fouling the probe tip. This reliability is essential when the housing is feeding data into emergency shutdown systems (ESD), where a single false trip or a missed vibration peak could result in millions of dollars in mechanical failure or lost production.

Global Logistics and Quality Assurance

We guarantee the product arrives in Original Factory Sealed condition, maintaining its E-E-A-T technical authority from the manufacturer to your site.

Maintenance and Technical Queries

Q1: Can I replace the internal probe without removing the 31000 housing from the machine?

A1: Yes. One of the primary advantages of this assembly is the "External Access" design. You can remove the rear cover and replace the probe while the housing remains bolted to the bearing cap.

Q2: What is the significance of the 3/4-14 NPT connection on the -02 suffix?

A2: This is the standard conduit port size. It allows you to run shielded cable through armored conduit directly into the housing, ensuring EMI/RFI protection for the low-voltage vibration signal.

Q3: Does this housing include the proximity probe?

A3: No, the 31000 is the housing assembly only. The proximity probe (e.g., 330101 or 330105) must be ordered separately to match your specific measurement range and proximitor requirements.

Q4: Is the -03 stainless steel housing suitable for offshore applications?

A4: The 303 stainless steel used in this suffix is highly resistant to general corrosion. However, for extreme salt-spray environments, we recommend verifying local site specs; 316 stainless steel variants are available for high-salinity offshore platforms.
