Bently Nevada 330103-00-12-10-02-00 – 3300 XL 8 mm Proximitor Sensor for Critical Machinery Vibration and Position Monitoring

The Bently Nevada 330103-00-12-10-02-00 is a 3300 XL 8 mm Proximitor Sensor, designed to pair with 3300 XL 8 mm proximity probes and extension cables to deliver stable, low-noise displacement and vibration signals on turbines, compressors, and large rotating assets. From my experience, this model is chosen when reliability in tough environments matters more than anything—particularly where consistent 200 mV/mil (≈7.87 mV/µm) scaling is expected by existing protection systems.

Company’s Order Placement Process and Guarantees

• Warranty period: 365 days
• Delivery time: typically 1 week if in stock; no more than one month at the latest
• Payment terms: 50% advance payment; full payment prior to delivery
• Express carriers: FedEx, UPS, DHL

Key Features

• 3300 XL 8 mm system compatibility – Works with 330130 series probes and 330180 extension cables for a tuned system length.
• Standard Bently scaling – 200 mV/mil (≈7.87 mV/µm) output simplifies integration with existing monitors and PLC inputs.
• Stable bias and dynamic signal – Provides DC gap (position) plus AC vibration for protection and condition monitoring in one channel.
• Rugged, epoxy-sealed module – Built for industrial cabinets and harsh machine environments; typically resists oil mist and vibration.
• Low-noise performance – Clean signal path helps reduce nuisance trips on high-speed rotors.
• Optioned build – This exact code is a factory configuration; you might notice it aligns with specific approvals and system length requirements.

Technical Specifications

Application Fields

This sensor is widely used on:

• Steam and gas turbines – radial vibration and thrust position feedback to protection systems
• Compressors and expanders – monitoring shaft stability and detecting rubs or clearance changes
• Pumps and fans – trending vibration to reduce unplanned downtime
• Gearboxes and generators – condition monitoring in high-speed trains of rotating equipment

One thing I appreciate is how consistent the 3300 XL series is across machines. A maintenance engineer at a combined-cycle plant told us the 330103 helped cut nuisance trips after they upgraded old drivers—the output stability seems to be better in noisy environments.

Advantages & Value

• Reliability in harsh areas – Potting and shielding help maintain a clean signal near large motors and high EMI.
• Compatibility – Standard Bently scaling integrates smoothly with 3500, 3701/40, and many third‑party monitors expecting 200 mV/mil.
• Lifecycle cost savings – Stable calibration typically reduces false trips and unscheduled callouts.
• Technical support – We can validate option codes (system length/approvals) against your BOM to avoid mismatches.

Installation & Maintenance

• Mounting – Install the Proximitor module on a rigid, vibration-tolerant surface inside a protective enclosure; keep cable runs tidy and strain‑relieved.
• Cabinet standards – Use a ventilated industrial enclosure; avoid high‑temperature zones and heavy power cabling to minimize EMI.
• Wiring – Follow the tuned system length for probe + extension cable; use proper shielding and grounding per Bently Nevada guidelines.
• Safety – De‑energize the circuit before adjustments; verify polarity for the -24 Vdc supply; check insulation resistance in humid areas.
• Routine care – Periodic verification of gap voltage and scale factor; inspect connectors for oil ingress; keep firmware/monitor settings aligned with your sensor configuration.
• Calibration – In most cases, field functional checks (bias and vibration response) are sufficient; full calibration can be scheduled during major outages.

Quality & Certifications

• CE compliant; RoHS compliance typical for current production
• UL/CSA and ATEX/IECEx variants are available depending on option code
• Manufacturer’s standard warranty is typically 1 year; we provide a 365‑day warranty on supply

Supported Components (for a complete measurement chain)

• 330130-XXXX-XX – 3300 XL 8 mm Proximity Probes (various tip, thread, and cable options)
• 330180-XXXX-XX – 3300 XL Extension Cables matched to system length
• Monitors – Bently Nevada 3500 series, 3701 series, or compatible condition monitoring systems expecting 200 mV/mil inputs

Note on options: the code “330103-00-12-10-02-00” corresponds to a specific factory configuration (e.g., approvals, mounting and system length). If you share your existing probe and cable codes, we can quickly confirm exact compatibility before shipment—this avoids mix‑and‑match issues that occasionally pop up in the field.
