Quick Detail

Description

The 330708-00-20-10-12-00 3300 XL 11 mm Proximity Probe is a high-performance eddy current transducer engineered for advanced industrial automation and machinery monitoring. It provides a 3.94 V/mm (100 mV/mil) output for precise, non-contact vibration and displacement measurements on fluid-film bearing machines. The 11 mm probe tip allows a longer linear range than the standard 8 mm 3300 XL system, making it ideal for axial (thrust) position detection, ramp differential expansion monitoring on steam turbines, rod position measurement on reciprocating compressors, tachometer and zero speed detection, and Keyphasor phase reference signals. The system uses gold-plated brass ClickLoc connectors that lock securely, and a patented TipLoc molding method for robust probe-tip bonding. The CableLoc design ensures probe-cable attachment strength up to 330 N (75 lbf). The probe features an IP67-rated stainless steel housing for dust and water resistance, and is compatible with FluidLoc cables to prevent oil or fluid leakage. Operating across –40°C to +85°C, this transducer system is designed for reliability in harsh industrial environments. Upgrading from 7200-series systems requires replacement of all components and possible monitoring system updates, ensuring full system integrity and optimal performance.

Applications

Axial Thrust Position Measurement
Accurately monitors thrust bearing displacement in turbines and large compressors, helping to prevent rotor instability.

Ramp Differential Expansion Measurement
Tracks thermal expansion in steam turbine rotors with precision, enabling predictive maintenance and efficiency optimization.

Reciprocating Compressor Rod Position
Provides real-time rod drop detection and position monitoring to reduce mechanical stress and prevent downtime.

Tachometer and Zero Speed Detection
Generates precise speed signals for rotating machinery control systems, improving safety and performance.

Phase Reference (Keyphasor) Signals
Delivers reliable Keyphasor outputs for vibration analysis, rotor balancing, and condition monitoring in large rotating equipment.

Specifications

Competitive Advantage

Extended Linear Range
The 11 mm probe tip allows longer linear measurement compared to standard 8 mm systems, reducing the need for multiple probes.

Robust Mechanical Design
Patented TipLoc and CableLoc designs enhance mechanical integrity, providing up to 330 N (75 lbf) pull strength.

High Environmental Resistance
IP67-rated housing and optional FluidLoc cables protect against dust, water, and oil contamination.

Secure Connections
Gold-plated ClickLoc connectors lock firmly, preventing signal loss or disconnection in harsh industrial environments.

Seamless Upgrade Path
Designed to replace 7200-series 11 mm and 14 mm systems, supporting modern 3300 XL components for improved performance and compatibility.
