Technical Specifications

Configuration Breakdown and Suffix Codes

• Model 330905: 3300 NSv Probe, M10X1 thread without armor
• Unthreaded Length Option (-00): 00 mm unthreaded portion
• Overall Case Length Option (-12): 120 mm total case length
• Total Length Option (10): 1.0 meter (39 in) cable length
• Connector & Cable Type (-02): Miniature coaxial ClickLoc connector with standard cable
• Agency Approval (-00): Not required / standard commercial grade

Installation Guide

Mount the probe using the M10X1 thread configuration into the machine housing. Tighten finger-tight initially, applying a maximum case torque of 0.56 N·m (5 in·lb) or per thread specifications. Route the 75-ohm FEP insulated cable away from high-voltage conduits. Maintain a minimum bend radius of 25.4 mm (1.0 in) to protect the coaxial cable.

Commissioning and Maintenance Convenience

Set the initial cold gap to the recommended 1.0 mm (40 mils) using a digital multimeter. Verify the -1 to -13 Vdc output range matches baseline clearances. ClickLoc connectors ensure secure, fast physical coupling during loop checks and routine calibrations.

Compatibility Notes

This unit is mechanically and electrically interchangeable with legacy 3300 RAM proximity probes. It works seamlessly with matching 3300 NSv Proximitor Sensors and extension cables up to 305 meters.

Certifications and Warranty Terms

Manufactured under strict ISO quality systems. Backed by a full 12-month factory warranty covering material and workmanship defects.

Shipping and Logistics

Fulfilled via reliable carriers including FedEx, UPS, and DHL. Emergency replacement parts dispatch within 24 to 48 hours globally.

Application Scenarios and Diagnostics

Deploys effectively in centrifugal air compressors, refrigeration compressors, and small turbo-machinery where tight side-view clearances restrict standard probes. Built-in system diagnostics identify open circuits, shorted cables, and supply voltage faults instantly through Proximitor monitoring outputs.

Global PLC Spare HUB's Insight

Our engineering team deployed the 330905-00-12-10-02-00 on a high-speed centrifugal compressor train with restricted radial mounting space. The superior side-view characteristics eliminated cross-talk interference from adjacent probe installations, ensuring stable vibration logging without false alarms during transient startup loads.

Frequently Asked Questions

Q: What causes a sudden shift in the DC gap voltage during steady-state operation?

A: Thermal growth of the machine shaft or mechanical loosening of the mounting bracket usually triggers a baseline gap voltage drift.

Q: How does the NSv probe design improve measurement accuracy on small shafts?

A: Its smaller tip diameter and refined electromagnetic field profile minimize edge-effect errors on targets under 13 mm in diameter.

Q: What precautions are necessary when routing the coaxial field cable?

A: Avoid sharp kinks below the 25.4 mm minimum bend radius to prevent altering the characteristic 75-ohm impedance.

Q: Can this probe withstand exposure to aggressive synthetic compressor lubricants?

A: Yes, the polyphenylene sulfide tip and fluoroethylene propylene cable insulation offer high chemical resistance against modern synthetic oils.

Q: What selection factors matter most when replacing a legacy 3300 RAM probe?

A: Verify that the thread size, unthreaded length, and cable length match your existing bracket layout to maintain identical scaling factors.
