330876-01-90-00-00 Bently Nevada 50 mm Proximity Probe
330876-01-90-00-00
330876-01-90-00-00 is a Bently Nevada 3300 XL 50 mm proximity probe with 1/2-20 threaded case, a 9 m high-temperature FluidLoc lead, no armor, and no agency approvals (safe-area option). 330876-01-90-00-00 is one component of a matched 50 mm transducer system for steam-turbine expansion measurement; 330876-01-90-00-00 alone does not deliver complete-system performance.
Scope note: 330876-01-90-00-00 identifies 3300 XL 50 mm proximity probe only. Complete-system performance is labeled separately and does not apply to 330876-01-90-00-00 alone.

330876-01-90-00-00 is only the listed proximity probe; 330876-01-90-00-00 must be matched with the correct 50 mm probe, cable path and Proximitor Sensor configuration.
330876-01-90-00-00 does not independently provide the published complete-system range or scale factor. The official 27.9 mm range and 394 mV/mm average scale factor apply only to a complete matched 330876/330877/330878 chain under the published target and test conditions.
