Product Overview
Bently Nevada 330130-080-12-00 3300 XL 8mm Proximity Transducer: Seamless Replacement & Upgrade Solution
The Bently Nevada 330130-080-12-00 is an 8mm eddy-current proximity transducer designed for the 3300 XL Series continuous vibration monitoring system. As legacy installations running the original 3300 Series or early 3300 XL hardware approach end-of-life, plant engineers and reliability teams face increasing pressure to source verified replacement units that maintain signal chain integrity without requiring re-engineering of existing wiring, conduit runs, or Proximitor® driver configurations. This product page addresses that exact migration scenario: a direct, drop-in replacement for the 330130-080-12-00 transducer that preserves your existing system architecture while restoring full measurement confidence.
The 330130-080-12-00 operates on the standard Bently Nevada eddy-current sensing principle, generating a voltage output proportional to the gap between the probe tip and the observed rotating shaft. It is calibrated for use with the 330180 series Proximitor® extension cables and the 330130 series driver modules, making it fully interchangeable within any 3300 XL rack-mounted monitoring system. Whether your plant is running a 3500/42M Proximitor® I/O Module, a 3300/16 rack, or a legacy 3300/20 chassis, the 330130-080-12-00 slots into the existing probe-cable-driver chain without modification to the Proximitor® sensitivity setting or the system’s OK limit thresholds.

Seamless Upgrade Solutions
A successful 3300 XL proximity transducer replacement rarely involves a single component. In practice, field engineers replacing a worn or failed 330130-080-12-00 will simultaneously audit the surrounding signal chain. The 330180-51-05 extension cable (5-metre armoured coaxial) is the most common companion part: its impedance characteristics are matched to the 330130 probe series, and any degradation in the cable jacket—common after years of exposure to bearing housing heat and lubricant vapour—will corrupt the gap voltage reading even with a new probe installed. Similarly, the 330130 Proximitor® driver (typically mounted in a 3300/16 or 3500 rack slot) should be bench-tested for OK relay output and sensitivity drift before the new transducer is commissioned.
For plants migrating from a legacy 3300/20 chassis to a modern 3500/42M Proximitor® I/O Module, the 330130-080-12-00 is fully compatible with the new rack’s input card without any wiring changes at the junction box. The 3500 rack’s 3500/20 Rack Interface Module handles Modbus TCP and Ethernet/IP communication to the DCS or historian, so the transducer replacement can be completed during a short maintenance window without touching the control system configuration. If your plant uses a 3500/22M Transient Data Interface for waveform capture, the new probe’s signal will be immediately recognised by the existing channel configuration.
Plants running older 3300/65 Keyphasor® modules alongside radial vibration probes should verify that the Keyphasor® probe—often a 330980-50-05 or 330104-00-06 unit—is also within its calibration interval, since a degraded Keyphasor® signal will cause false 1× amplitude readings on the newly installed radial probe. Where the control cabinet houses a 3500/15 Power Supply, confirm that the −24 VDC rail is within ±1 VDC under full rack load before energising the replacement transducer. Finally, for installations where the probe is mounted in a high-vibration compressor or turbine bearing housing, consider pairing the 330130-080-12-00 with a 330100-90-05 armoured probe guard sleeve to extend service life in abrasive environments.
Retrofit Guidance FAQ
Q: Can I replace the 330130-080-12-00 without reconfiguring the Proximitor® driver?
A: Yes. The 330130-080-12-00 shares the same 200 mV/mil sensitivity and linear range as all standard 3300 XL 8mm probes. The Proximitor® driver’s OK limits, gap voltage setpoints, and alarm thresholds remain valid. No software or hardware reconfiguration is required.
Q: Is the wiring at the junction box compatible?
A: The probe uses a standard integral coaxial cable terminated at the extension cable connector. The junction box wiring—shield, centre conductor, and drain—is identical to the original installation. No re-termination is needed provided the extension cable (330180 series) is in good condition.
Q: Will this probe work with a 3500 Series rack as well as a 3300 Series rack?
A: Yes. The 330130-080-12-00 is compatible with both the legacy 3300/16 and 3300/20 racks and the current-generation 3500/42M Proximitor® I/O Module. The analog voltage output is rack-agnostic.
Q: What is the recommended gap setting after installation?
A: The standard gap for an 8mm probe on a steel shaft is 1.0–1.5 mm (40–60 mil), placing the operating point in the centre of the linear range. Verify with a calibrated gap tool and confirm the Proximitor® OK LED illuminates before returning the machine to service.
Q: How do I verify the replacement probe is functioning correctly before machine restart?
A: With the machine stationary, measure the DC gap voltage at the Proximitor® output terminals. It should read approximately −10 VDC at a 1.27 mm (50 mil) gap. Confirm the OK relay is energised and the channel reads within ±5% of the expected gap voltage. Then perform a slow-roll check to verify 1× and 2× vibration readings are within baseline.
Q: What if the physical installation space is constrained?
A: The 330130-080-12-00 has an M10 × 1 mounting thread and a standard 8mm probe body diameter, identical to all 3300 XL 8mm probes. No bracket modification or adaptor is required. The integral 1.0 m cable routes through the same conduit as the original probe.
Warranty Assurance
Every 330130-080-12-00 unit shipped by TOPNLMS carries a 12-month warranty covering manufacturing defects, sensitivity drift beyond specification, and connector or cable integrity failures. Prior to dispatch, each unit undergoes a pre-shipment functional test: gap voltage linearity is verified across the full 0.25–2.26 mm range, the OK output is confirmed, and the probe body and cable jacket are inspected for physical damage. Units that do not pass this test are not shipped.
