More Information

Overview Manuals System Matching Target & Mounting Cable & Environment Application
  • Use only matching 3300 XL 50 mm system components
  • Use the specified target size and verified target material
  • Route the 9 m FluidLoc cable without violating bend limits

Bently Nevada 330876-01-90-00-05 is a Bently Nevada 3300 XL 50 mm straight-exit proximity probe with 1/2-20 thread, 9.0 m high-temperature FluidLoc cable without armor and multiple approvals.

It is the field-sensing element of an extended-range eddy-current system used primarily for large steam-turbine differential-expansion or rotor-expansion measurement.

Before installation or replacement, verify the complete probe code, matching 3300 XL 50 mm extension cable and Proximitor Sensor, 9 m total system length, target geometry and material, mounting bracket, initial gap, cable routing and approval requirements.

Availability, condition, price, and shipping time for 330876-01-90-00-05 are confirmed during quotation.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can Bently Nevada 3300 XL 50 mm Probe 330876-01-90-00-05 be connected to a standard 8 mm or 11 mm Proximitor Sensor?
No. This probe must be used with matching 3300 XL 50 mm system components. An 8 mm or 11 mm Proximitor Sensor has a different calibrated scale and linear range and is not compatible with the 50 mm probe.
Does Bently Nevada 3300 XL 50 mm Probe 330876-01-90-00-05 require a separate extension cable?
No. This probe has a 9.0 m integral cable and must be matched with a 9.0 m 3300 XL 50 mm Proximitor Sensor. Do not add an extension cable, because changing the total electrical length invalidates the calibrated scale and linear range.
Why might Bently Nevada 3300 XL 50 mm Probe 330876-01-90-00-05 reach the end of its measurement range during turbine heat-up?
Check the initial cold gap, expected rotor and casing thermal growth, bracket orientation, available target travel, cable and connector condition, and monitor scaling. Applications with greater axial movement may require a correctly engineered complementary-probe arrangement.
Can Bently Nevada 3300 XL 50 mm Probe 330876-01-90-00-05 be calibrated against any metal target?
No. Published system accuracy and interchangeability specifications are based on a Bently Nevada AISI 4140 steel target. A different alloy, target thickness, diameter or geometry can change sensitivity and requires an approved target-specific calibration.
What should be inspected before reusing Bently Nevada 3300 XL 50 mm Probe 330876-01-90-00-05?
Inspect the probe tip, threaded case, locknut, FluidLoc cable jacket, connector, seals, strain relief and insulation condition. Also check the cable routing and bend radius, especially where the cable passes near hot turbine structures or could rub against moving components.
How should Bently Nevada 3300 XL 50 mm Probe 330876-01-90-00-05 be acceptance-tested after mounting?
Use the approved verification kit and calibrated micrometer to move the probe sliding carriage through a known travel. Verify gap voltage and scale across the working range, then confirm monitor direction, alarm operation, mechanical clearance and repeatability throughout the expected thermal movement.
Why is mounting-bracket selection important for Bently Nevada 3300 XL 50 mm Probe 330876-01-90-00-05?
Differential-expansion measurement requires repeatable axial movement between the probe and target. The bracket and clamp must match the probe exit direction, available collar geometry, expected travel, verification access and the required single-probe or complementary-input differential-expansion arrangement.
