Description

The Bently Nevada 330876-02-50-01-00 is a 3300 XL 50 mm proximity probe manufactured by Bently Nevada, a Baker Hughes company, originating from the USA. It belongs to the 3300 XL 50 mm Proximity Transducer System family, which provides an extended 50 mm linear range for large displacement measurements in rotating machinery.

The probe features an 8.0 mm diameter polyphenylene sulfide (PPS) probe tip mounted in a stainless steel case. The overall case length is 50 mm. The probe tip is non-metallic and electrically insulated from the case, preventing electrical interference and allowing direct contact with conductive target surfaces without short-circuiting the eddy current field.

The 330876-02-50-01-00 model includes a 2.0 metre (6.6 ft) integral probe cable with standard coaxial cable without armor. The cable is hermetically sealed to the probe case.

Information

Overview Manuals Application Notes Product Applications Mechanical Mounting & Gapping

Features:

  • 3300 XL 50 mm proximity probe
  • Non-contact eddy-current sensing technology
  • Large-range displacement measurement capability
  • Standard non-armored cable configuration
The probe utilizes eddy-current sensing technology to accurately detect the distance between the probe face and a conductive target surface. Changes in shaft position or machine movement are converted into electrical signals that are processed by compatible extension cables and Proximitor sensors, providing precise displacement measurements for machinery protection and condition monitoring systems.

The 50 mm probe system is particularly suitable for large rotating machinery where substantial shaft movement must be monitored. Typical applications include differential expansion measurement on steam turbines, casing expansion monitoring, thrust position measurement, shaft displacement monitoring, and structural movement measurement on large industrial equipment.

The 330876-02-50-01-00 Bently Nevada 3300 XL 50 mm Proximity Probe may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

The probe operates on the eddy current principle, generating a high-frequency electromagnetic field that induces eddy currents in a conductive target surface. The resulting impedance change is measured by the companion 3300 XL 50 mm Proximitor Sensor (330180 series), producing a DC voltage output proportional to the gap between the probe tip and the target surface. The system provides both static (position) and dynamic (vibration) measurement capability.

  • Centrifugal & Axial Compressors:Shaft imbalances & aerodynamic thrust surges
  • Generators & Gearboxes:Early warning to prevent catastrophic failures
  • Power Generation:Turbines, generators & exciter shafts: vibration/eccentricity
  • Oil & Gas / Petrochemical:High-speed centrifugal, process gas compressors & turboexpanders
  • Water & Waste Treatment:Multi-stage pumps & cooling tower fans

Target Material: Proximitor sensors are calibrated at the factory for AISI 4140 steel. If your target is made of a different material, you will need a customized calibration curve.
Target Size: Ensure the target collar is at least 102 mm (4.0 in) in diameter to provide a flat, adequate surface for the large 50 mm probe tip.
Gapping: While setting the gap (the distance between the probe tip and the target), utilize the linear measurement range of your specific model. Use a micrometer or dial indicator.
Alignment: Ensure the transducer remains perpendicular and perfectly aligned with the rotor during its axial movement.

Technical notes

The 50 mm probe system is particularly suitable for large rotating machinery where substantial shaft movement must be monitored. Typical applications include differential expansion measurement on steam turbines, casing expansion monitoring, thrust position measurement, shaft displacement monitoring, and structural movement measurement on large industrial equipment.
