The 330174-00-08-50-02-05 is a 5mm eddy current stainless steel armored proximity sensor probe manufactured by Bentley Nevada, USA, part of the 3300 series.
3300 5 mm probe
3300 XL extension cable (ref 141194-01)
3300 XL Proximitor Sensor 3, 4, 5 (ref 141194-01)
It is typically installed within the confined space of bearing housings in large compressors, gearboxes, and water pumps, providing precise, non-contact measurement of radial vibration, axial displacement, or key phase speed signals of high-speed rotating shafts. It delivers maximum mechanical durability against crushing, foot traffic, and harsh physical wear.As a 5-meter direct-connect probe system, its built-in cable plugs directly into a compatible 3300 XL 5-meter Proximitor Sensor without requiring any separate extension cable. The combined system provides a highly accurate, temperature-stable output voltage that is directly proportional to the dynamic or static distance from the conductive surface. Holding Multiple Approvals (ATEX, IECEx, CSA), this heavy-duty component is fully certified for safe, non-contact radial vibration, axial displacement, and Keyphasor/speed tracking in the harshest industrial hazardous zones.

Fossil Fuel Power Generation
Measuring the relative radial vibration of high-speed main shafts through potential physical-abrasion routing zones inside the ultra-narrow boreholes of compact small-scale speed-governing generator units or valve driving mechanisms.
Hydroelectric Power
Screwing into the original positions of auxiliary speed-measuring gearboxes with ultra-thin walls via its compact 5mm threaded case to measure the keyphasor polarity signals of speed gears in large vertical hydro-generator units.
Petrochemical & Refining
Monitoring the micron-level rotor axial thermal play against internal walls of high-pressure canned motor pumps within hazardous explosion-proof refinery zones, with the stainless steel armor protecting the cable against worker foot-traffic and mechanical cutting wear along complex external piping routes.
Pulp & Paper
Monitoring the axial displacement of paper machine press rolls under high-speed operation, where the stainless steel armor resists mechanical tensile fatigue along messy routing lines on highly humid, steam-heavy internal sidewalls of roll bearing housings.
Pharmaceutical
Screwing and tightening seamlessly into the miniature boreholes of compact shaft sleeves on high-speed sterile vertical centrifuges or high-precision homogenizers to online monitor micron-level agitation eccentricity and dynamic imbalance.
First, the flat metal target diameter must not be less than 11mm, otherwise the measurement sensitivity will be distorted. Second, a precise initial gap voltage calibration (around -9Vdc) is required to ensure accurate coverage of the shaft amplitude within its limited range. Third, during routing, even with armor protection, the bend radius must never be less than 25.4mm, and direct contact with high-power equipment casings must be avoided to prevent electromagnetic interference. Fourth, when connecting the miniature ClickLoc terminal, keep it clean and dry and lock it with a connector protector, while strictly complying with hazardous area wiring codes.
It is a 3300 series 5mm eddy current stainless steel armored explosion-proof proximity probe, manufactured by Bently Nevada, USA.
What is the primary purpose of 330174-00-08-50-02-05?
It is primarily installed inside the confined bearing housing spaces of large industrial rotating machinery (e.g., high-pressure pumps, compressors) for non-contact measurement of radial shaft vibration, axial displacement, or keyphasor speed.
How should 330174-00-08-50-02-05 be used and connected within a system?
It must first be screwed into the machinery mounting bracket, and then its 5.0-meter integrated cable is connected directly to a matching 3300 series Proximitor Sensor using the tail-end ClickLoc self-locking connector.
How long is the armored cable built into 330174-00-08-50-02-05?
According to the "-50" option in the code, this probe comes with an integrated stainless steel armored triaxial cable with a total length of 5.0 meters (approximately 16.4 feet).
Is an extension cable required in the field when using 330174-00-08-50-02-05?
No, this model is a 5-meter direct-connect probe, and its 5.0-meter built-in cable already satisfies the electrical length specifications of a typical 5-meter Proximitor system.
