Bently Nevada 330180-X1-05 MOD145004-67 — 8mm Eddy-Current Proximity Transducer | 3300 XL Series Platform
Engineering Background
The Bently Nevada 3300 XL Series represents the industry benchmark for continuous machinery protection in rotating equipment applications. Developed by Baker Hughes (Bently Nevada), the 3300 XL platform is engineered to meet API 670 requirements for turbomachinery monitoring, delivering sub-micron resolution and exceptional signal stability in the harshest industrial environments.
Product Positioning
The 330180-X1-05 MOD145004-67 is an 8 mm eddy-current proximity transducer designed for radial vibration, axial position, and differential expansion measurement on steam turbines, gas turbines, compressors, and large rotating machinery. It is the preferred choice for procurement engineers requiring API 670-compliant, drop-in replacement components with full system compatibility.

System Architecture & Signal Flow
The 330180-X1-05 operates as part of the complete 3300 XL three-component system:
- Probe (330180-X1-05): Eddy-current sensing element — mounts directly to bearing housing or machinery casing
- Extension Cable (330130-XX-XX): System-matched, impedance-controlled cable — transmits raw oscillator signal from probe to driver
- Proximitor® Driver (3300 XL series): Signal conditioning module — converts raw signal to calibrated DC voltage output for monitor input cards
Output feeds directly into Bently Nevada 3500 Series rack monitors, System 1® software, or any API 670-compliant monitoring system via standard ±24V loop.

Technical FAQ
Q: Is the 330180-X1-05 compatible with the Bently Nevada 3500/42M monitor?
A: Yes. The 3300 XL probe system is fully compatible with all 3500 Series monitor input cards when paired with the correct 3300 XL Proximitor® driver.
Q: What is the difference between 330180-X1-05 and 330180-X1-CN-05?
A: The “-CN-” suffix denotes a connector-style variant. The base sensing element and scale factor are identical; only the cable termination differs. Confirm your driver input connector before ordering.
Q: Can this probe measure on stainless steel shafts?
A: Eddy-current sensitivity varies with target material conductivity and permeability. For non-standard alloys (316 SS, Inconel, titanium), a field calibration against the actual target is required. Contact our engineering team for target correction factors.
Q: Do you provide ATEX documentation?
A: Yes. ATEX/IECEx certificates and EC Declaration of Conformity are available upon request for all 3300 XL series components.
Q: What is the minimum order quantity?
A: MOQ is 1 unit. Volume pricing available for orders of 5+ units.
