Description
The 330876-02-90-00-00 3300 XL 50 mm Proximity Probe is a large-range eddy current proximity probe designed for applications requiring extended displacement measurement beyond the capabilities of conventional proximity transducers. As part of the 3300 XL 50 mm Transducer System, the probe provides a maximum linear measurement range of 27.9 mm, making it particularly suitable for differential expansion and rotor expansion monitoring in large steam turbine-generator units.
The 3300 XL 50 mm Transducer System consists of a separate50 mm probe, an extension cable, and a 3300 XL 50 mmProximitor Sensor. The large diameter coil gives this system amaximum linear range of 27.9 mm (1100 mils), the longestlinear range of our eddy current transducer line. This linearrange makes the 3300 XL 50 mm Transducer System ideal formeasuring the differential expansion (DE) or rotor expansion(RX) of large steam turbine generators that results from thedifference in growth rates between the turbine rotor and themachine stator (casing).

- Multiple case and thread configurations
- Physical replacement compatibility
The probe operates continually at temperatures up to 200°C (392°F) and withstands intermittent temperatures up to 250°C (482°F). It has a front seal and a rear seal. Combined with the High Temperature FluidLoc cable, these seals prevent moisture from entering the probe tip.
The 330876-02-90-00-00 Bently Nevada 3300XL 50 mm proximity probe may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Machine Target: This specific variation (Rjo 04104) is engineered as an OEM component for Pignone MS5002 turbine trains, tracking critical shaft vibration or thrust displacement.
Environmental Armoring: The probe incorporates a stainless steel braided armor sleeve to shield the internal extension wiring from high-velocity oil splash, thermal stress, and physical abrasion inside turbine housings.
Proximitor Requirement: Like all Bently Nevada eddy-current sensors, this probe cannot function as a standalone device. It requires calibration to a matching Bently Nevada Proximitor sensor module to translate radio frequency (RF) gap changes into a linear voltage or current signal.
- Steam Turbine Generators:Rotor-casing differential expansion
- Gas Turbines:Axial/structural expansion near heat zones
- Hydroelectric Turbines:Shaft wobble & thrust from hydraulic loads
- Marine Propulsion Systems:Thermal expansion for shafts & gearboxes.
- Steel Rolling Mills:Roll-gap/thrust under cyclic peak loads
- Large Cooling Tower Fans:Alignment & vibration across long couplings

Thread Details: This specific variant (-02) features a metric M14x1.5 thread.
Torque Specifications: Secure the threaded case using the integrated locknut. Torque it to a recommended value of 68 N·m (50 ft·lb). Do not exceed the maximum rating of 163 N·m (120 ft·lb)
Side Clearance (Free Space): To prevent the probe from "seeing" the sides of the mounting bracket or turbine casing, maintain a completely clear cylinder around the probe tip. Avoid placing any extraneous metal within a radius equal to at least 2 to 3 times the probe tip diameter.
Technical notes
The 330876-02-90-00-00 features an M14×1.5 threaded stainless-steel housing with a straight-exit configuration and a 9-meter High-Temperature FluidLoc cable. The probe incorporates front and rear environmental seals to prevent moisture ingress, while the high-temperature cable construction enables reliable operation in severe turbine environments where elevated temperatures and oil contamination are common. Continuous operation is supported at temperatures up to 200°C, with short-duration exposure capability up to 250°C.
FAQs
-
What is the 330876-02-90-00-00 ？
+The Bently Nevada 330876-02-90-00-00 is a highly specialized 3300 XL 50 mm Proximity Probe for demanding industrial applications, particularly for monitoring differential expansion on steam turbines. -
What environments is this probe built for?
+The 50 mm probe is engineered to survive the harshest steam turbine environments. It maintains accuracy in continuous high temperatures up to 200°C and can withstand intermittent spikes up to 250°C. -
What components make up the complete transducer system?
+For the 9.0-meter system to function accurately, the probe must be paired with an appropriate 3300 XL 50 mm Extension Cable and a 3300 XL 50 mm Proximitor Sensor. -
What are its temperature limitations?
+The probe is highly resilient against intense heat. It safely sustains continuous operational temperatures from -51°C up to +200°C (-31°F to +392°F), and can tolerate brief peaks up to 250°C (482°F).
