Product Introduction
The Bently Nevada 330180-90-05 is a 3300 XL Proximitor Sensor used with an eddy-current proximity probe and extension cable to form a non-contact displacement measurement system. It converts the probe’s gap-dependent signal into a proportional voltage suitable for machinery-monitoring equipment. Typical measurements include shaft vibration, axial position, and Keyphasor-related speed or phase reference.
This configuration provides a 9.0 m total system length and panel-mounted housing, with CSA, ATEX, and IECEx approvals. The probe, extension cable, and Proximitor should be treated as one engineered measurement chain when verifying replacement compatibility and installation configuration.

Installation & Configuration Guide
Estimated replacement time: 30–60 minutes, excluding machine shutdown, gap verification, and machinery-protection testing.
Stage 1 — Pre-Installation Preparation
- Verify the installed Proximitor part number and confirm the required replacement is 330180-90-05.
- Record the existing probe and extension-cable part numbers.
- Confirm that the required system configuration is 9.0 m total electrical length.
- Verify the replacement has the required CSA, ATEX, and IECEx approval configuration for the installation.
- Prepare labels, suitable hand tools, a multimeter, ESD protection, and the applicable Bently Nevada installation documentation.
- Back up machinery-monitoring configuration and record existing vibration/position readings.
- Apply the plant’s LOTO procedure before accessing the machinery-protection system.
⚠️ Do not substitute a 1.0 m or 5.0 m Proximitor configuration merely because the housing and connectors appear identical. System length is part of the transducer configuration.
Stage 2 — Removing the Old Proximitor
- Confirm the monitored machine is in its approved maintenance state.
- Isolate the relevant electrical power according to plant procedures.
- Identify and label the probe-extension connection and monitor output wiring.
- Disconnect the extension cable from the Proximitor.
- Disconnect the Proximitor output wiring from the monitoring system.
- Remove the panel-mount hardware.
- Inspect the removed sensor and retain it for comparison.
- Check the cable connector for corrosion, contamination, or mechanical damage.
⚠️ Do not pull on the coaxial cable to disconnect the connector. Handle the connector body to avoid damaging the mating interface.
Stage 3 — Installing the New Proximitor
- Verify the replacement marking 330180-90-05.
- Confirm the sensor is the panel-mount 9.0 m configuration.
- Mount the Proximitor in the original panel position.
- Connect the compatible extension cable.
- Connect the Proximitor output to the corresponding machinery-monitoring channel.
- Verify polarity and wiring against the applicable system drawing.
- Ensure cable routing keeps the signal wiring away from avoidable electrical interference sources.
- Do not alter the probe gap simply to compensate for an incorrect Proximitor configuration.
The 3300 XL system is designed around compatible probe, extension-cable, and Proximitor components. The complete system configuration should be verified before commissioning.
Stage 4 — Power-On & Testing
- Inspect all connections and mounting hardware.
- Restore power according to the plant startup procedure.
- Verify the Proximitor output is stable.
- Check the corresponding monitor channel for a valid displacement signal.
- Verify the probe gap and DC bias voltage according to the applicable 3300 XL procedure.
- Compare the measured vibration or axial-position value with the pre-maintenance baseline.
- Check for excessive noise, signal drift, or intermittent readings.
- Test the applicable alarm and trip functions using the approved machinery-protection procedure.
- Record the installed Proximitor part number and final test results.
⚠️ Do not clear a machinery-protection fault solely because the new Proximitor powers up. A valid measurement requires the probe, extension cable, Proximitor, monitor input, and configuration to operate correctly as a complete signal chain.
FAQ
Q1. What is Bently Nevada 330180-90-05?
It is a 3300 XL Proximitor Sensor configured for a 9.0 m total system length, panel mounting, and CSA/ATEX/IECEx approvals. It conditions the signal from a compatible eddy-current proximity probe and extension cable.
Q2. What does the “90” mean in 330180-90-05?
The 90 designator identifies the 9.0 m / 29.5 ft total system-length, panel-mount configuration. It does not mean that the Proximitor itself is 9 m long.
Q3. What does the “05” suffix indicate?
The 05 approval option identifies the version with CSA, ATEX, and IECEx approvals. The exact hazardous-area installation must still comply with the applicable certification and plant electrical requirements.
Q4. What probes are compatible with 330180-90-05?
The documented input accepts a compatible 3300-series 5 mm, 3300 8 mm, or 3300 XL 8 mm proximity probe and extension cable. The complete probe/cable/Proximitor configuration must satisfy the required system electrical length and application requirements.
Q5. Can 330180-90-05 be used with a 5 m extension cable?
Not as a simple substitution. The 9.0 m system configuration is an ordering parameter, so changing the probe or extension-cable combination changes the total electrical system length. Verify the complete configuration against the applicable Bently Nevada documentation before making the substitution.
Q6. Does 330180-90-05 require programming?
No conventional firmware programming is required for the Proximitor itself. It is an analog signal-conditioning component. Correct probe selection, extension-cable length, mechanical gap, wiring, and monitor configuration are the important commissioning parameters.
Q7. Is 330180-90-05 obsolete?
Commercial listings are inconsistent: some suppliers describe the part as legacy/EOL while others currently list OEM-available or new-original inventory. Therefore, do not infer condition or lifecycle status from the part number alone. Confirm the actual unit’s manufacturing status, calibration status, revision, and condition before purchase.
