330104-00-13-05-02-CN Bently Nevada 3300 XL 8 mm Proximity Probe

Engineering Specification & Configuration Breakdown

This technical summary details the Bently Nevada 330104-00-13-05-02-CN proximity transducer system from the 3300 XL 8 mm product family. Designed for precision vibration and displacement monitoring, this assembly incorporates strict dimensional and material tolerances to ensure high-accuracy machinery protection.

Core Metrological & Electrical Parameters

• Manufacturer & Series: Bently Nevada, 3300 XL Series
• Linear Range: 2.0 mm (80 mils) operating range, spanning from 0.25 to 2.25 mm gapped from target
• Incremental Scale Factor (Sensitivity): Approximately 7.87 mV/μm (200 mV/mil) under standard calibration
• Frequency Response: 0 to 10 kHz (-3 dB) flat response for dynamic vibration tracking
• Power Supply Requirements: -17.5 Vdc to -26 Vdc at 12 mA maximum consumption (-23 Vdc to -26 Vdc with safety barriers)
• Output Resistance: 50 Ohms nominal source impedance
• Probe DC Resistance: 7.59 ± 0.50 Ohms center-to-outer conductor resistance for a 1.0m system path

Physical Construction & Environmental Tolerances

• Probe Tip Material: Polyphenylene sulfide (PPS) injection-molded matrix
• Probe Case Material: AISI 303 or 304 corrosion-resistant stainless steel
• Pressure Sealing: Viton O-ring designed to seal differential pressures up to 100 psi between tip and case
• Operating Temperature Range: Minus 51 degrees Celsius to plus 177 degrees Celsius for probe tip
• Environmental Resilience: High resistance to synthetic lubricants, moisture, and industrial petrochemical exposure

Mechanical Installation & Clearance Guidelines

Thread the 330104-00-13-05-02-CN probe into a rigid mounting bracket, ensuring the M10 x 1 threads engage smoothly without binding. Secure the locknut against the bracket face to maintain precise mechanical gapping relative to the AISI 4140 steel target. Route the armored cable away from high-voltage motor leads, securing it with insulated clamps to prevent high-frequency electromagnetic interference.

Maintenance, Diagnostics & Calibration Protocol

Perform routine loop checks by measuring static gap voltage using a high-impedance digital multimeter connected to the Proximitor sensor output terminals (-24 Vdc supply baseline). Inspect ClickLoc connector joints annually for oxidation, moisture ingress, or mechanical loosening. Verify that system linearity matches the baseline calibration curve to detect probe tip degradation or micro-fractures in the coaxial core.

Quality Assurance, Terms & Fulfillment Logistics

• Warranty Protection: Comprehensive 12-month replacement warranty against manufacturing defects
• Shipping Methods: Expedited dispatch via FedEx, UPS, and DHL
• Fulfillment Speed: Orders process and ship within 24 to 48 hours globally
• Compliance Standards: Conforms to API 670 standards for non-contacting vibration monitoring systems

Industrial Equipment & Typical Application Environments

• Steam turbines and heavy industrial gas turbine generator sets
• Multi-stage centrifugal compressors and turbo-blowers
• Large hydroelectric turbine shafts and vertical pump bearings
• Critical industrial gearboxes and high-speed centrifugal pumps

Comparative Selection & Model Evaluation

When engineering a vibration monitoring rack, selecting the correct cable length and armor configuration is vital for signal integrity. Below is an alternative configuration model for comparative technical evaluation:

• Alternative Option: 330104-00-04-50-02-05
• Technical Advice: The alternative model features a shorter 40mm case length and a longer 5.0-meter cable length configuration. If your mechanical mounting depth requires a compact case profile with extended routing distance to the Proximitor enclosure, use the linked alternative model. For shallow, armored retrofits requiring a 130mm case and a 0.5-meter drop lead, stick with the 330104-00-13-05-02-CN variant.

Global PLC Spare HUB Insight

Field engineering reviews indicate that premature signal drift in proximity probes often stems from improper grounding of the shield drain wire at the monitor rack. When deploying the 330104-00-13-05-02-CN system, ensure that the extension cable shield is left floating at the barrier strip and grounded exclusively at the Proximitor chassis to prevent ground loops that distort sub-synchronous vibration readings during high-load turbine transients.

Expert Frequently Asked Questions

Question:
How does the 130mm overall case length impact the physical placement of the probe?

Answer:
The 130mm rigid case provides extended reach through thick bearing housings or mounting sleeves before transitioning to the flexible armored lead.

Question:
What precise target material is required to maintain the specified 200 mV/mil sensitivity?

Answer:
The system calibration curve strictly requires a flat AISI 4140 carbon steel target to maintain accurate displacement output scaling.

Question:
What purchasing factors should an instrumentation technician evaluate when selecting the CN agency approval option?

Answer:
Verify local regulatory compliance laws in your specific country of installation to ensure country-specific hazardous area classification alignment.

Question:
Why does the multimeter output read near zero volts when power is applied to the circuit?

Answer:
A zero-volt reading typically indicates an open circuit in the coaxial cable, a disconnected power supply rail, or a shorted probe tip conductor.

Question:
Can an extension cable be added to the 0.5-meter integral cable version without recalibration?

Answer:
Yes, provided you pair it with a matching 3300 XL Proximitor sensor and a total system length (probe plus extension cable) matching either 5 meters or 9 meters.
