Quick Detail

Description

The 330730-080-01-00 3300 XL 11 mm Extension Cable is an armored automation cable used with the 3300 XL 11 mm proximity transducer system for machine protection and displacement monitoring. The 330730-080-01-00 3300 XL 11 mm Extension Cable provides an 8.0 m connection between probe and proximitor using 75 Ω triaxial FEP-insulated conductors and flexible AISI 302 stainless steel armor. With 50 Ω output resistance, the 330730-080-01-00 3300 XL 11 mm Extension Cable transfers the 3.94 V/mm probe signal required for turbine and compressor position measurement.

Rated from −52°C to +177°C, 330730-080-01-00 3300 XL 11 mm Extension Cable can be routed near bearing housings and process equipment. The 330730-080-01-00 3300 XL 11 mm Extension Cable accepts 0.2–1.5 mm² field wiring and limits supply influence to less than 2 mV per volt, supporting vibration monitoring, keyphasor input, and shutdown logic in automated control cabinets. In rotating equipment monitoring systems, 330730-080-01-00 3300 XL 11 mm Extension Cable delivers non-contact shaft displacement data for protection relay operation.

Applications

Monitor turbine thrust position

Installed between the thrust probe and the monitor, 330730-080-01-00 3300 XL 11 mm Extension Cable transfers the displacement signal through its 75 Ω triaxial conductor. Because 330730-080-01-00 3300 XL 11 mm Extension Cable has 50 Ω output resistance, the 8.0 m routing does not reduce signal level, allowing accurate trip points when axial shaft movement increases.

Measure casing to rotor expansion during startup

During turbine heating, probes mounted on casing and rotor send expansion data through 330730-080-01-00 3300 XL 11 mm Extension Cable. The −52°C to +177°C temperature rating of 330730-080-01-00 3300 XL 11 mm Extension Cable permits installation near hot steam sections while the <2 mV/V supply influence keeps expansion values unchanged during motor starting.

Detect rod drop in reciprocating compressors

The rod position probe connects to the protection relay using 330730-080-01-00 3300 XL 11 mm Extension Cable. Because 330730-080-01-00 3300 XL 11 mm Extension Cable accepts 0.2–1.5 mm² wiring, technicians terminate the cable directly at relay terminals and transmit displacement data required for shutdown commands.

Provide phase reference pulse for speed monitoring

A keyphasor probe outputs one pulse per revolution through 330730-080-01-00 3300 XL 11 mm Extension Cable. The triaxial shielding in 330730-080-01-00 3300 XL 11 mm Extension Cable reduces electromagnetic pickup from motors so the monitor calculates shaft phase and rotational speed correctly.

Specifications

Competitive Advantage

Route cable beside rotating machinery without conduit

The stainless steel armor on 330730-080-01-00 3300 XL 11 mm Extension Cable protects the FEP insulated conductors, allowing 330730-080-01-00 3300 XL 11 mm Extension Cable to be placed directly along turbine decks and compressor skids.

Install next to high temperature bearing housing

With operating capability up to 177°C, 330730-080-01-00 3300 XL 11 mm Extension Cable can be mounted near journal bearings. The FEP insulation of 330730-080-01-00 3300 XL 11 mm Extension Cable prevents signal degradation caused by heat exposure.

Connect directly into monitoring rack terminals

Because 330730-080-01-00 3300 XL 11 mm Extension Cable supports standard 0.2–1.5 mm² field wiring, maintenance staff can wire 330730-080-01-00 3300 XL 11 mm Extension Cable directly into protection systems without adapters.

Prevent false shutdown during power fluctuation

The supply sensitivity below 2 mV per volt means 330730-080-01-00 3300 XL 11 mm Extension Cable keeps probe output constant when panel voltage changes, ensuring trip logic reacts only to real shaft displacement measured through 330730-080-01-00 3300 XL 11 mm Extension Cable.
