100630-08-15-15-01 Bently Nevada Submersible Proximity Probe In Stock

Product Overview

The 100630-08-15-15-01 is a specialized underwater proximity probe from the 3300 XL 8mm Series manufactured by Bently Nevada. Engineed for submerged machine monitoring applications where the probe body is continuously exposed to or immersed in industrial fluids, this eddy current sensor measures shaft vibration, axial position, and speed reference without signal degradation.

Constructed with a 304 Stainless Steel sealed body (3/8-24 UNF thread) and protective Tefzel tubing over the coaxial cable sheath, the 100630-08-15-15-01 is pressure-sealed to withstand up to 34 Bar (500 psi) Nitrogen pressure. The design prevents fluid ingress along the cable jacket while operating reliably across hazardous area zones.

Technical Specifications

Installation & Mounting Guidelines

• Connector Submersion Warning: The probe casing and Tefzel tubing are fluid-sealed, but the ClickLoc connector end is NOT liquid-proof and must remain un-submerged in a dry enclosure.
• Fluid Compatibility Limit: The 304 Stainless Steel housing is engineered for industrial oils and fresh water; do NOT install in salt-water/brine environments to prevent pitting corrosion.
• Casing Installation Torque: Tighten the 3/8-24 UNF threaded 304 SST casing to a maximum torque of 8.5 N·m (75 in·lb) using a calibrated wrench.
• Tefzel Tubing Routing: Maintain a minimum bend radius of 38.1 mm (1.5 in) along the Tefzel protective sheath to prevent kinking or internal cable pinching.
• Connector Protector Assembly: Ensure the elastomeric connector protector is fully seated over the ClickLoc coupling before closing terminal junction boxes.

Field Calibration & Inspection Procedures

• Pressure Seal Verification: Inspect Tefzel tubing compression fittings at the probe casing transition for oil seepage during high-pressure machine testing.
• DC Gap Voltage Check: Verify gap voltage output on connected 3300 XL Proximitor sensor measures -9.0 Vdc (~1.27 mm / 50 mils gap offset) under zero dynamic shaft motion.
• Insulation Resistance Check: Measure resistance from connector center pin to outer 304 SST case; verify reading exceeds 100 MΩ at 500 VDC test voltage.

System Compatibility & Field Wiring Integration

The 100630-08-15-15-01 integrates directly with 3300 XL 8mm extension cables and Proximitor Sensors. Signal outputs feed into Bently Nevada 3500 machinery monitoring systems or Orbit 60 racks via 3-conductor shielded triad field cables (16 to 24 AWG) up to 305 meters (1,000 feet).

Environmental Protection & Safety Certifications

• 34 Bar Pressure Sealing: Seals up to 500 psi internal pressure differential across machine fluid barriers.
• Chemical Isolation: Outer Tefzel armor protects coaxial cable insulation against chemical degradation from synthetic lube oils and industrial solvents.
• Explosion-Proof Ratings: Certified intrinsically safe (Ex ia) when wired via zener barriers or galvanic isolators per Bently Nevada drawing 141092.

Model Selection & Comparison

Matching total electrical length and connector protection options is vital for wet machine housing installations. Compare these variant configurations:

• Target Model: 100630-08-15-15-01
  • Unthreaded / Case Length: 0.8 in unthreaded (-08) / 1.5 in case (-15)
  • Total Cable Reach: 1.5 meters (4.9 feet) system cable length (-15)
  • Connector Interface: ClickLoc connector WITH rubber connector protector (-01)
• Alternative Variant: 100630-08-15-90-02
  • Unthreaded / Case Length: 0.8 in unthreaded (-08) / 1.5 in case (-15)
  • Total Cable Reach: Extended 9.0 meters (29.5 feet) total system reach (-90)
  • Connector Interface: ClickLoc connector WITHOUT connector protector (-02)

Selection Guidance: Specify the 100630-08-15-15-01 for installations requiring a compact 1.5m lead with factory connector protection inside an adjacent junction box. Choose the 100630-08-15-90-02 when the probe lead must exit the wet machine housing directly to an external monitor rack without using an intermediate extension cable.

Industrial Applications & Fault Diagnostics

Plant reliability teams deploy 3300 XL 8mm Series submersible probes across demanding fluid-immersed industrial machinery:

• Submerged Hydro-Turbines: Continuous tracking of shaft radial vibration and thrust bearing wear inside water-flooded runner housing cavities.
• Submersible Wastewater Pumps: Shaft orbit dynamic profiling and mechanical seal wear monitoring in submerged pump volutes.
• Gearbox Sump Cavities: Continuous vibration monitoring immersed directly inside synthetic lubricating oil reservoirs.
• Industrial Agitators & Mixers: Measurement of shaft deflection in liquid-filled process vessel stuffing boxes.

Global PLC Spare HUB's Insight

In wet machinery applications, standard proximity probes often fail due to fluid wicking along internal cable braiding. This causes dielectric changes in the coaxial lead, leading to calibration shift and erratic Proximitor output readings. The 100630-08-15-15-01 addresses this by sealing the 304 SST probe head and enclosing the coaxial lead in Tefzel tubing, creating a barrier rated to 34 Bar.

During a overhaul on a submerged hydro-turbine generator, technicians replaced water-damaged standard probes with 100630-08-15-15-01 assemblies. By routing the Tefzel-jacketed leads to a dry external junction box, the plant eliminated moisture-related signal drift and restored stable baseline vibration readings. Always confirm the ClickLoc connector remains in a dry atmosphere above the maximum fluid line.

Frequently Asked Questions (FAQ)

Q: Why is this submersible probe explicitly not recommended for salt-water or marine environments?

A: The casing is constructed from 304 Stainless Steel, which suffers pitting corrosion and stress corrosion cracking when exposed to chloride-rich salt water over extended periods.

Q: Can the entire length of the cable and ClickLoc connector be submerged under water or oil?

A: No, only the probe casing and Tefzel tubing section are liquid-sealed; the ClickLoc connector end is unsealed and must remain in a dry, un-submerged location.

Q: What is the benefit of the connector protector supplied with option -01?

A: The elastomeric protector slips over the ClickLoc junction to shield the gold-plated pins from dust, high ambient humidity, and incidental oil splatters inside the dry junction box.

Q: How do I verify if a probe pressure seal has failed after high-pressure nitrogen or oil exposure?

A: Disconnect the probe from the extension cable and inspect the internal Tefzel tubing cavity for fluid accumulation or measure insulation resistance between center conductor and outer shield (drops below 100 MΩ when flooded).

Q: How do I choose between a 1.5-meter total length probe and a 9.0-meter total length probe for submerged installations?

A: Measure the distance from the submerged mounting point to the dry external casing wall. If the dry junction box sits within 1.5 meters of the machine penetration, choose the 1.5m model; if routing continuously out of a deep pit or sump directly to a monitor cabinet without an internal splice, select a 9.0m model.
