Product Description
The 330104-00-20-05-02-00 is a precision 8mm eddy-current proximity probe from the 3300 XL series manufactured by Baker Hughes - Bently Nevada.
This high-accuracy transducer is designed for non-contact vibration, displacement, and phase reference (Keyphasor) monitoring of rotating machinery. The probe generates a voltage signal proportional to the distance between the probe tip and conductive shaft surfaces, enabling reliable machinery protection for turbines, compressors, and other high-speed rotating equipment.
The probe features a 3/8-24 UNF threaded body and a 2.0-inch case length, making it suitable for mid-depth mounting applications such as bearing housings. The -02 ClickLoc connector option provides moisture-resistant, vibration-secured electrical connection to the Proximitor sensor, improving long-term signal stability.
The -00 suffix indicates a standard industrial configuration without hazardous area certification, making it suitable for non-explosive environments where temperature stability and measurement linearity are primary requirements.

Operational Capabilities and Installation
The 330104-00-20-05-02-00 is commonly used in machinery protection systems for:
-
Radial shaft vibration monitoring
-
Axial thrust displacement measurement
-
Phase reference / speed measurement (Keyphasor applications)
For optimal system performance, this probe should be paired with:
-
3300 XL extension cables
-
3300 XL Proximitor sensors
The 0.5-meter lead cable is typically combined with 4.5 m or 8.5 m extension cables, resulting in standard calibrated system lengths of 5 m or 9 m total.
During installation, technicians must set a static gap voltage, typically around -10 VDC, using calibration tools such as the TK-3 test instrument to position the probe within its linear measurement region.
FAQ
What is the benefit of the 0.5 m lead length?
The shorter lead reduces internal cable clutter inside machine housings and minimizes signal interference caused by excessive coiled cabling.
Can this probe be used in explosive environments?
No. This version does not include intrinsic safety certifications. For hazardous locations, variants with ATEX, IECEx, or CSA approvals should be selected.
What is the ClickLoc connector?
The ClickLoc system is a gold-plated coaxial connector that provides a vibration-resistant, moisture-sealed connection with a tactile locking feedback mechanism, helping maintain stable signal transmission.
