Technical Specifications

Installation Guide

Set initial probe gap to -10 Vdc (±0.5 V) for standard operation. Maintain minimum 6 mm clearance from target surface. Torque to 12–15 N·m for mounting. Ensure cable routing with minimum 50 mm bend radius. For hazardous area installations, verify CN approval restrictions apply.

Engineering Advantages

This 3300 XL probe delivers exceptional thermal stability (±0.03%/°C) and robust IP67 sealing for harsh environments. The ClickLoc connector ensures secure, vibration-proof cable attachment. Wide frequency response (0.5 Hz–10 kHz) captures both slow roll and high-speed vibration events.

Technical FAQs

Q1: How to set the correct probe gap?
A1: Adjust the probe to achieve -10 Vdc output (±0.5 V) at the driver. This corresponds to the recommended 1.27 mm (50 mils) nominal gap for 8 mm probes.

Q2: What does -CN approval mean?
A2: The -CN suffix indicates country-specific approvals for China. Refer to the certification documents for any voltage or installation restrictions.

Q3: Can this probe replace older 3300 series probes?
A3: Yes, the 3300 XL probe is backward-compatible with existing 3300 series systems and offers improved thermal performance and longer cable options.
