Quick Detail

Description

The 330730-040-01-05 3300 XL 11 mm Extension Cable is engineered as part of the 3300 XL 11 mm Proximity Transducer System, widely applied in industrial automation, vibration monitoring, and machinery diagnostics. Designed to support non-contact measurement in axial thrust, rod position, and expansion monitoring applications, this extension cable features a 75 Ω triaxial FEP-insulated construction with optional AISI 302 stainless-steel armor for enhanced durability. The 4.0 m cable length option and ClickLoc connector system ensure secure transmission of the system’s 3.94 V/mm (100 mV/mil) output across fluid film bearing machines and steam turbine assets. Built to withstand harsh industrial temperatures ranging from -52°C to +177°C, the 330730-040-01-05 3300 XL cable supports field wiring flexibility from 16 to 24 AWG, enabling integration into turbines, compressors, and energy-sector equipment. The 3300 XL architecture also serves as a direct upgrade path from older 7200-series systems, combining longer linear range performance with improved monitoring compatibility and enhanced environmental protection for predictive maintenance and condition-based automation strategies.

Applications

Industrial Steam Turbine Thrust Position
Used for axial thrust position monitoring on steam turbines where the extended linear range of the 3300 XL 11 mm system enables accurate displacement tracking under thermal expansion. Supports outputs at 3.94 V/mm for integration with 3500 monitoring platforms.

Reciprocating Compressor Rod Position and Rod Drop
Applied in reciprocating compressors to measure rod motion and rod drop events, allowing plants to predict wear and optimize uptime. The 4.0 m armored cable option improves survivability under vibration and lubricant exposure.

Differential Expansion in High-Temperature Turbomachinery
Ideal for high-temperature ramp differential expansion measurements from −52°C to +177°C operating range, reducing thermal mismatch errors in energy, petrochemical and power generation units.

Keyphasor/Phase Reference in Condition Monitoring Systems
Supports phase reference and tachometer functions for automated rotor dynamics analysis and balancing systems, enabling accurate RPM and zero-speed capture for digital control and diagnostics.

Zero-Speed Detection for Machinery Protection Systems
Used in safety and protection applications for zero-speed and near-zero detection on large rotating machinery. Facilitates automated interlocks and trip logic in industrial monitoring systems.

Specifications

Competitive Advantage

Extended Linear Measurement Range
Compared with standard 8 mm systems, the 11 mm design increases usable linear range for axial and expansion measurements, improving diagnostic accuracy on steam turbines and compressors.

High Thermal Durability
Certified for extreme temperature operation from −52°C to +177°C, outperforming many conventional proximity cable assemblies in energy, refining and heavy machinery environments.

Robust Signal Integrity
Utilizes 75 Ω triaxial FEP-insulated architecture with 50 Ω output resistance for stable measurement transmission over long cable runs and electromagnetic interference conditions.

Secure Mechanical Protection
Optional flexible AISI 302 stainless armor with FEP jacket enhances field survivability in lubricated, abrasive or vibration-rich environments, reducing maintenance interruptions.

Upgrade and Integration Compatibility
Designed as a forward-compatible replacement for legacy 7200-series systems and optimized for 3500 monitoring software, supporting modernization of rotating equipment condition monitoring.
