Company’s Order Placement Process and Guarantees

  • Warranty: 365 days

  • Delivery: In-stock items ship in about 1 week; no more than one month at the latest

  • Payment: 50% advance; full balance prior to delivery

  • Express options: FedEx, UPS, DHL

Key Features

  • Reverse-mount 8 mm probe head – Helps protect the sensing tip and cable in confined or abrasive environments.

  • True 3300 XL performance – When used with the 3300 XL Proximitor sensor and extension cable, you get the classic 200 mV/mil (7.87 V/mm) sensitivity and stable long-term output.

  • System length matching – The “-05” option typically indicates a 5 m system length configuration for proper factory calibration across probe + extension + Proximitor.

  • Cable configuration – “-12” commonly denotes a 12 ft integral probe cable to help reach the junction to the extension cable without splices.

  • Threading for retrofit – “-02” is commonly 3/8-24 UNF-2A, making it a straightforward drop-in for many North American housings.

  • Industrial-grade sealing – Designed for oil-splash, steam, and general plant environments; typically IP68 near the probe tip.

  • Compatibility – Works with 3300 XL extension cables and 3300 XL Proximitor sensors in 5 m or 9 m systems (ensure all three components are matched).

Technical Specifications
Brand / Model Bently Nevada 330105-02-12-05-02-CN (3300 XL 8 mm Reverse-Mount Probe)
HS Code 9031.80 (Measuring or checking instruments, not elsewhere specified)
Probe Type Non-contact eddy-current proximity probe, reverse-mount body
Tip Diameter 8 mm (0.315 in)
Thread Type (Probe Body) Typically 3/8-24 UNF-2A for “-02” option
Sensitivity (with 3300 XL system) 7.87 V/mm (200 mV/mil)
Linear Range (typ.) 2.0 mm (80 mils) on standard 5 mm/8 mm systems
Nominal Gap (typ.) 1.0 mm (40 mils) to mid-range
Operating Temperature (Probe) -51 to +177 °C (-60 to +350 °F), typical for 3300 XL probes
Signal Input/Output Types Coaxial connection to extension cable; displacement signal provided by 3300 XL Proximitor
Power Requirements None (passive probe; powered/conditioned by Proximitor)
Communication Interfaces N/A (analog signal via Proximitor)
Installation Method Reverse-mount with jam nut; aimed at conductive targets (e.g., AISI 4140 steel)
Dimensions & Weight 8 mm tip; reverse-mount body; integral cable length per “-12” option (probe-only mass is low)
Configuration Notes “-05” matched for 5 m system length; “-CN” typically indicates Chinese-language labeling
Application Fields

These probes show up most in critical rotating equipment where long-term stability matters. In many cases, teams standardize on 3300 XL for plant-wide vibration and axial position monitoring.

  • Steam and gas turbines: shaft vibration and thrust position

  • Compressors (centrifugal/recip): bearing vibration, rotor radial position

  • Pumps and fans: unbalance/looseness detection and clearance trending

  • Gearboxes: mesh-related vibration, shaft runout tracking

  • Large motors and generators: sleeve bearing condition monitoring

A maintenance lead at a combined-cycle plant told us their reverse-mount 8 mm probes “survived both hot starts and frequent inspections without losing calibration,” which seemed to be the small reliability edge they were after.

Advantages & Value

  • Reliability – 3300 XL probes are known for thermal stability and low drift over time.

  • Compatibility – Drop-in with 3300 XL extension cables and Proximitor sensors; easy to standardize spares.

  • Lifecycle cost – Reverse-mount design typically reduces cable damage and rework, saving labor during outages.

  • Traceability – Clear part coding helps you match the system length correctly, avoiding recalibration headaches.

  • Support – We can help confirm thread specs, system length, and accessories before you commit the PO.

Installation & Maintenance

  • Mounting – Install from inside the machine case using the jam nut; verify the thread (the “-02” option is typically 3/8-24 UNF).

  • Target material – Calibrated for conductive steel (e.g., 4140). If you have non-standard materials or coatings, let us check linearity impacts.

  • Gap and alignment – Set the static gap near mid-range (about 1.0 mm/40 mils). Align the probe tip normal to the shaft surface.

  • Cable routing – Avoid tight bends and high-temperature zones; keep the coax away from high EMI sources when possible.

  • Enclosure & wiring – Place the Proximitor in a ventilated control cabinet; maintain proper grounding/shielding and clean terminal connections.

  • Verification – After installation, confirm sensitivity (200 mV/mil) and polarity using a micrometer or calibrated motion fixture.

  • Routine care – Periodic inspection of the tip face for debris buildup, check jam-nut tightness, and confirm cabling integrity during outages.

Quality & Certifications

  • Typically conforms to CE and RoHS directives for industrial instrumentation

  • Manufactured under ISO 9001 quality systems

  • Hazardous area approvals may apply depending on full system configuration (probe + extension + Proximitor)

  • Manufacturer’s warranty: 12 months (365 days)

Recommended Supporting Components

  • 3300 XL Extension Cable – Match the length so the total system equals the “-05” 5 m configuration.

  • 3300 XL Proximitor Sensor (5 mm/8 mm system) – Provides the 200 mV/mil output and power to the probe.

  • Mounting hardware – Jam nut and protective sleeves as required by the machine casing.

One thing I appreciate is that once the three components are correctly matched, you rarely need field recalibration—swaps during outages go quicker and trending stays consistent.
