Information
- 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.

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.
Verify the complete 330876-01-50-01-05 marking and 1 1/2-20 threaded execution before work.
Place the monitored machine and protection channel in the approved maintenance state.
Protect the sensing tip, threads and mounting surface from impact, burrs and contamination.
Route and support the 5.0 m (16.4 ft) lead without sharp bends, crushing, tensile load or contact with moving parts.
Keep coaxial connector faces clean, dry and mechanically unloaded during handling.
Confirm the matched 3300 XL 50 mm electronics, total system length and target material before setting gap.
Preserve the documented probe separation and cable shielding arrangement during installation.
Prove gap voltage, polarity, dynamic response and alarm action before returning the channel to service.
