The 330854-040-25-05 is a Bently Nevada 3300 XL 25 mm extension cable with a 4.0 m electrical length, stainless-steel armored high-temperature FluidLoc construction, and the multiple-approvals option.
- 3300 XL 25 mm armored extension cable
- 4.0 m (13.1 ft)
- High-temperature FluidLoc
- Flexible AISI 302 stainless steel with PFA jacket
It connects a 1.0 m 330851 differential-expansion probe to a 5.0 m 330850 Proximitor Sensor, carries the eddy-current measurement signal, and completes the electrical length used to measure rotor-to-stator differential expansion on steam-turbine generators. For dependable measurement, follow the official system-matching, target, mounting, cabling, environmental, and approval instructions.
Important Notice: The 4.0 m cable must be matched with a 1.0 m probe and 5.0 m 330850 Proximitor Sensor; system length is part of the calibration.
Apter Power 330854-040-25-05 Original Product Manual
Important Notice: This Apter Power original manual summarizes manufacturer-published technical data for the exact ordering code. Verify the physical nameplate and current manufacturer installation documents before use.
Steam-Turbine Differential ExpansionConnects the 25 mm probe system used to measure rotor-to-stator growth differences.
Turbine Supervisory InstrumentationCarries the differential-expansion signal toward the 330850 Proximitor Sensor and TSI monitoring channel.
High-Temperature Cable RoutesPFA-insulated FluidLoc cable is rated for the published -35°C to +200°C range.
Armored Machinery WiringFlexible stainless-steel armor protects the cable in mechanically demanding turbine installations.
Single Differential-Expansion InputSupports a 5 m 25 mm system used with the short sliding-bracket arrangement.
Complementary MeasurementsCan be used in matched complementary-input arrangements when each probe system follows the official bracket and system-length requirements.
Read and follow Bently Nevada 3300 XL 25 mm Proximity Transducer System Datasheet 163236 Rev. M and the applicable installation instructions before use. Verify the complete ordering code from the physical nameplate and match every component to the published system configuration.
1Use with a 1.0 m 330851 probe so the combined electrical length equals the 5.0 m Proximitor Sensor setting.
2Maintain the 25.4 mm minimum bend radius and do not crush the armor or PFA jacket.
3Protect and finger-tighten the miniature ClickLoc connections; prevent contamination at the joints.
4Route within the published cable temperature range and keep the Proximitor Sensor within its separate environmental limits.
5Verify the 05 approval markings, current certificates, barriers, and installation drawings before hazardous-area use.
