Quick Detail

Description

The 3300 XL 11 mm Proximity Probe (Model 330707-00-25-10-02-00) is a high-precision eddy current transducer designed for non-contact vibration and displacement measurement in automated industrial systems. Featuring an 11 mm probe tip, this transducer delivers a linear output of 3.94 V/mm (100 mV/mil), enabling extended linear range measurements compared to the standard 3300 XL 8 mm probes. With a total length of 1.0 meter (3.3 feet) and a compact 2.5-inch overall case length, it integrates seamlessly with miniature coaxial ClickLoc connectors and industry-standard RJ45 connectors, ensuring secure, lock-in-place connections. Engineered for harsh environments, it offers IP67-rated dust and water resistance and operates reliably in temperatures from -40°C to +85°C. The 3300 XL 11 mm probe incorporates a patented TipLoc molding method and CableLoc design with 330 N (75 lb) pull strength, enhancing mechanical durability. Optional FluidLoc cables prevent oil or fluid leakage from machinery, making this probe ideal for fluid-film bearing machines, thrust position monitoring, and automated Keyphasor or tachometer systems. The system supports full replacement of older 7200-series 11 mm and 14 mm transducers and ensures compatibility with updated 3500 Monitoring System software, providing precise, long-term performance in critical industrial automation applications.

Applications

1. Axial (Thrust) Position Monitoring
The 3300 XL 11 mm probe provides precise non-contact axial position measurement in turbines and compressors, with a linear range suitable for detecting small thrust changes during high-speed operation, improving automated machine protection.

2. Differential Expansion Measurement
Ideal for ramp differential expansion monitoring in steam turbines, the 11 mm tip ensures extended linear range readings, supporting automated thermal growth compensation and reducing mechanical stress in rotating equipment.

3. Rod Position and Rod Drop Detection
Used on reciprocating compressors, the probe delivers high-accuracy rod displacement measurements. Its output of 3.94 V/mm enables real-time monitoring for automated safety shutdowns if rod misalignment occurs.

4. Tachometer and Zero-Speed Measurement
Provides reliable non-contact speed signals for rotating machinery. The robust probe design with 330 N cable pull strength ensures stable readings for automated control systems in industrial plants.

5. Phase Reference (Keyphasor) Signal Generation
Enables precise Keyphasor signals for synchronous vibration analysis. The IP67-rated enclosure and gold-plated ClickLoc connectors maintain signal integrity in automated systems under humid or high-temperature conditions.

Specifications

Competitive Advantage

1. Extended Linear Range with Large 11 mm Tip
The larger tip delivers 3.94 V/mm output, allowing longer linear measurement ranges than standard 8 mm probes, reducing the need for frequent probe adjustments in automated systems.

2. Robust Mechanical Integrity
TipLoc molding and CableLoc designs provide 330 N (75 lb) pull strength, ensuring long-lasting durability and minimal maintenance in high-vibration industrial automation environments.

3. Environmental Resistance and Reliability
IP67-rated protection and optional connector protectors make this probe suitable for harsh conditions, preventing dust and water ingress, critical for continuous automated operation.

4. Compatibility and Upgrade Flexibility
Supports full replacement of legacy 7200-series 11 mm and 14 mm systems. Compatible with updated 3500 Monitoring System software, allowing smooth integration into modern automated monitoring setups.

5. Fluid Containment and Safety
Optional FluidLoc cables prevent machine oil or liquid leaks, maintaining operational safety and environmental compliance while enabling uninterrupted automated measurements of vibration and position.
