Technical Specifications

Selection Comparison & Technical Guidance

When configuring enclosures within the 32000 product family, matching the probe penetration and thread standard to your machine casing is essential. Below is a technical comparison with an alternative configuration:

• Model Comparison: Compare against the alternative variant 32000-00-00-04-470-01-02. While both utilize the robust PPS thermoplastic enclosure design, the comparison model features a different probe option (-00 for standard probes), zero standoff adapter, and an extended penetration profile (-470), whereas the 32000-28-10-00-085-03-02 is built specifically for integrated 3300 XL 8mm probe assemblies (-28) with an 85 mm penetration depth and M20 armored cable fitting.
• Selection Advice: Ensure your machinery probe mounting port matches the 3/4-14 NPT thread specification. If your installation requires armored cable protection in wet or corrosive plant zones, the -03 fitting package provides the necessary cable seal grip and M20 port configuration without secondary modifications.

Installation Guide & Mounting Best Practices

• Apply approved thread sealant to the 3/4-14 NPT mounting threads before threading the housing securely into the machine casing port.
• Route the 3300 XL probe cable through the M20 fitting and cable seal grip, ensuring the Neoprene grommet compresses tightly around armored shielding to maintain IP66 integrity.
• Torque exterior stainless steel cover screws evenly to prevent distortion of the Neoprene O-ring seal during thermal cycling.
• Ground the conductive PPS housing properly to satisfy CENELEC standard EN50014 requirements for electrostatic dissipation in hazardous zones.

Typical Equipment & Application Scenarios

• Large Steam & Gas Turbines: Protecting radial vibration and axial position proximity probes near high-temperature bearing caps.
• Centrifugal & Axial Compressors: Housing internal displacement sensors exposed to heavy washdown and oil mist environments.
• Hydroelectric Generators: Securing vibration monitoring lines in damp, high-humidity subterranean plant levels.

Diagnostic Capabilities & Maintenance

• The rigid PPS housing structure eliminates mechanical flexing around the probe tip, preventing false vibration spikes caused by enclosure resonance.
• Stainless steel retaining chains secure the housing cover during routine maintenance, preventing dropped hardware inside operating machinery.
• Sealed M20 cable entry prevents moisture ingress, eliminating short-circuits that cause drift in proximity probe gap voltage readings.

Packaging, Warranty & Shipping

• Package List: 1 x Bently Nevada 32000-28-10-00-085-03-02 metric proximity probe housing assembly.
• Warranty: Backed by a comprehensive 12-month quality assurance warranty.
• Logistics: Rapid 24-48 hour dispatch via Fedex, UPS, and DHL.

Buying Guide & Selection Tips

• Verify that your probe tip diameter matches the 8 mm specification required by the -28 internal probe option.
• Confirm that your total probe cable run inside the housing aligns with the 1.0 m (39 in) allocation before coiled storage in the base.

Frequently Asked Questions

Question
What type of cable protection does the -03 fittings option provide for this housing?

Answer
The -03 fittings package includes two plugs, one M20 fitting, and one cable seal grip equipped with grommets specifically sized for armored probe cables.

Question
What environmental ingress protection ratings does the PPS housing hold?

Answer
It is certified by CSA to Type 4X standards and verified to IP66 rating standards by test report SC115582-1 (e) 106.

Question
Can this housing withstand sub-zero operating temperatures?

Answer
Yes, it is rated for operational temperatures down to -51°C (-60°F) and certified by BASEEFA to withstand physical impacts at -39°C.

Question
Why is the housing material manufactured with conductive fibers?

Answer
The conductive fibers embedded in the glass-reinforced PPS thermoplastic facilitate electrostatic dissipation, meeting CENELEC EN50014 safety mandates for hazardous atmospheres.

Question
What is the exact probe penetration depth designed for this model code?

Answer
The -085 suffix indicates an 85 mm probe penetration depth into the machinery measurement zone.

Global PLC Spare HUB's Insight

Global PLC Spare HUB's Insight reveals that improper torque on cable gland grommets is a primary root cause of moisture contamination in field probe enclosures. When maintenance personnel over-tighten or misalign the M20 cable seal grip on armored probe lines, the Neoprene grommet pinches unevenly, allowing condensation to wick into the housing over successive thermal cycles. Field technicians should hand-tighten the fitting until snug, then apply a final quarter-turn with a wrench to achieve a watertight seal without crushing the internal coaxial cable dielectric.
