Bently Nevada 330876-01-90-00-00 50 mm Proximity Probe
A straight-exit 1/2-20 threaded probe with 9.0 m unarmored FluidLoc cable and no approvals.
Key Information
330876-01-90-00-00 is a 3300 XL 50 mm proximity probe configured with a 1/2-20 threaded case, 9.0 m total probe cable, unarmored high-temperature FluidLoc cable and the no-approvals option.
This long-range probe belongs to the 50 mm differential-expansion transducer system. It must be paired with the matching 9 m Proximitor Sensor rather than a 5 m sensor.
Functions
- Observes the target without contact for differential-expansion or rotor-expansion measurement.
- Provides the sensing element for the calibrated 3300 XL 50 mm transducer loop.
- Uses the straight-exit threaded case for mechanically secured turbine installations.

Installation
- Confirm case thread, cable routing, bend radius and available connector clearance against the machine drawing.
- Pair the 9.0 m probe directly with the correct 9 m sensor arrangement; do not add a length-changing extension cable.
- Set the mechanical position from the official collar-height and probe-position guidance.
- Verify gap voltage and expansion direction through the full approved movement check.
Lifecycle
- Protect the unarmored FluidLoc cable from abrasion and hot sharp edges.
- Retain the exact case, cable and approval codes in the loop record.
- Replace all transducer-system components together when upgrading from an earlier 50 mm system.
FAQ
Can 330876-01-90-00-00 be connected to a 5 m Proximitor Sensor?
No. The 90 length code requires the matching 9.0 m 3300 XL 50 mm system calibration.
Is the cable on 330876-01-90-00-00 armored?
No. The armor code is 00, which specifies high-temperature FluidLoc cable without armor.
What thread does 330876-01-90-00-00 use?
The case code 01 specifies a straight-exit 1/2-20 threaded probe case.
Does 330876-01-90-00-00 carry the multiple-approvals option?
No. The final 00 identifies the no-approvals execution.
What buyer evidence reduces risk for 330876-01-90-00-00?
Provide the old probe label, sensor label, cable route, mounting drawing, target material and required hazardous-area status.
