The 330876-01-10-00-00 is a Bently Nevada 3300 XL 50 mm non-contacting eddy-current proximity probe with a 1/2-20 threaded straight-exit case, a 1.0 m high-temperature FluidLoc cable without armor, and no agency approval option.
- 1/2-20 threaded straight exit
- 1.0 m (3.3 ft)
- High-temperature 75 ohm triaxial PFA FluidLoc, no armor
- 00 - no approvals
With a 4.0 m 330877 extension cable and a 5.0 m 330878 Proximitor Sensor, it forms the 50 mm system that measures large axial displacement. Its 27.9 mm linear range is intended principally for differential expansion or rotor expansion on large steam turbine-generators, using one or two probes aimed at a collar or ramp target. For dependable operation, follow the official system-matching, mounting, wiring, environmental, and approval instructions.
Important Notice: Use only a matched 1 m probe plus 4 m extension plus 5 m sensor. Verify 1/2-20 engagement, target and collar geometry, full axial travel, cable protection, and option-00 status.
Apter Power 330876-01-10-00-00 Manuals and Guides
Important Notice: These are two separate Apter Power documents prepared from the official Bently Nevada source named in each document. Confirm the physical nameplate, current manufacturer documentation, and applicable installation drawing before installation or replacement.
Steam Turbine Differential Expansion
Measures rotor-to-casing growth differences over a long linear range.
Rotor Expansion
Tracks large axial growth of turbine-generator rotors.
Collar Targets
Supports one or two probes observing the same side of a collar.
Complementary Input DE
Two probes on opposite sides can extend the total measurable range.
High-Temperature Interiors
The probe and FluidLoc cable tolerate elevated turbine-case temperatures.
Legacy 7200 Upgrades
The 3300 XL 50 mm family can replace prior 7200 50 mm systems only when every system component is replaced.
Read and follow the official manufacturer source and applicable installation instructions before use. Verify the exact complete ordering code from the physical nameplate.
1
Use a 4.0 m 330877 extension cable and 5.0 m 330878 sensor; do not mix 5 m and 9 m components.
2
Limit 1/2-20 thread engagement to 0.750 in and follow the official mounting, locknut, and safety-wire instructions.
3
Maintain a 25.4 mm cable bend radius and keep every ClickLoc connection clean, protected, and free of mechanical load.
4
Verify the 102 mm target, collar height, expected axial movement, mounting geometry, and full-range movement before commissioning.
5
Do not infer hazardous-area approval: final option 00 orders no agency approval.
