Quick Detail

Description

The 330730-040-03-05 3300 XL 11 mm Extension Cable provides a 4.0-meter (13.1 ft) connection for 3300 XL 11 mm Proximity Probes, enabling accurate non-contacting vibration and displacement measurements on fluid-film bearing machines. The cable features 75 Ω triaxial FEP insulation and optional flexible AISI 302 stainless steel armor with FEP outer jacket. Operating from -52°C to +177°C (-62°F to +351°F), the 330730-040-03-05 3300 XL 11 mm Extension Cable supports field wiring from 0.2 to 1.5 mm² (16–24 AWG), with an output resistance of 50 Ω and supply sensitivity under 2 mV per volt. Gold-plated miniature coaxial ClickLoc connectors with connector protectors ensure secure attachment to probes and Proximitor sensors, while optional FluidLoc cables prevent oil or liquids from entering the cable interior. The 330730-040-03-05 3300 XL 11 mm Extension Cable is fully compatible with the 3300 XL 11 mm Proximity Probe and allows upgrades from older 7200-series 11 mm and 14 mm systems without monitor modifications. This cable maintains accurate signal transmission for applications including axial position measurement, ramp differential expansion monitoring, rod position tracking, and Keyphasor signal acquisition.

Applications

Axial Position Measurement on Fluid-Film Bearings
The 330730-040-03-05 3300 XL 11 mm Extension Cable transmits precise signals from the 3300 XL 11 mm Proximity Probe, allowing accurate axial (thrust) position measurement on turbines and compressors. Its 4.0-meter length supports flexible installation across large machinery.

Ramp Differential Expansion Monitoring on Steam Turbines
Using the 330730-040-03-05 3300 XL 11 mm Extension Cable with 3300 XL 11 mm Proximity Probes, operators can monitor differential expansion between rotor and casing ramps. Its 75 Ω FEP-insulated triaxial design ensures minimal signal loss over long distances.

Rod Position Tracking on Reciprocating Compressors
The 330730-040-03-05 3300 XL 11 mm Extension Cable provides robust signal transmission for rod position or rod drop measurements, supporting field wiring from 0.2 to 1.5 mm² (16–24 AWG) and maintaining a linear response of 50 Ω output resistance.

Keyphasor Signal Acquisition
The 330730-040-03-05 3300 XL 11 mm Extension Cable reliably connects 3300 XL 11 mm Proximity Probes to Proximitor sensors, enabling accurate phase reference (Keyphasor) signals for rotor speed monitoring. Its optional armored construction and connector protectors prevent electrical noise and liquid ingress.

Specifications
