Information

Overview Manuals Common Applications Product Precautions
Bently Nevada 330876-01-50-01-05 is 3300 xl 50 mm 1 1/2-20 threaded proximity probe. It measures large shaft or rotor displacement without contact and feeds a matched 3300 XL 50 mm Proximitor Sensor and monitoring input.
  • Uses the documented 1 1/2-20 threaded body
  • Carries the signal over a 5.0 m (16.4 ft) FluidLoc lead
  • Provides the large-range 50 mm sensing interface
  • Operates only as part of a matched 3300 XL 50 mm system

330876-01-50-01-05 operates with 3300 XL 50 mm Proximitor Sensor, matched extension cable when required, 102 mm or larger steel target, compatible displacement monitor.

Engineered applications include Turbine differential expansion, Large axial-position measurement, Valve and rotor travel monitoring, 50 mm transducer-loop renewal.

Important Notice: Confirm the 1 1/2-20 threaded body, 5.0 m (16.4 ft) lead, stainless-steel and multiple approvals; match the probe and extension cable to the Proximitor system length before full-travel calibration.

The first document provides model-specific technical and system-reference information. The second is the directly related manufacturer document used for installation, configuration and engineering verification.

Turbine differential expansion

Measures large thermal rotor movement.

Large axial-position measurement

Tracks axial position over an extended mechanical travel.

Valve and rotor travel monitoring

Supports differential-expansion protection functions.

50 mm transducer-loop renewal

Restores the exact probe element in a calibrated 50 mm system.

Read the applicable Bently Nevada instructions before work. Verify 330876-01-50-01-05 and the installed 3300 XL 50 mm Proximity Transducer System configuration.
1

Verify the complete 330876-01-50-01-05 marking and 1 1/2-20 threaded execution before work.

2

Place the monitored machine and protection channel in the approved maintenance state.

3

Protect the sensing tip, threads and mounting surface from impact, burrs and contamination.

4

Route and support the 5.0 m (16.4 ft) lead without sharp bends, crushing, tensile load or contact with moving parts.

5

Keep coaxial connector faces clean, dry and mechanically unloaded during handling.

6

Confirm the matched 3300 XL 50 mm electronics, total system length and target material before setting gap.

7

Preserve the documented probe separation and cable shielding arrangement during installation.

8

Prove gap voltage, polarity, dynamic response and alarm action before returning the channel to service.

Technical notes

Confirm the 1 1/2-20 threaded body, 5.0 m (16.4 ft) lead, stainless-steel and multiple approvals; match the probe and extension cable to the Proximitor system length before full-travel calibration.
