The 330173-03-08-05-02-05 is a 3300 5 mm non-contact proximity probe manufactured by Bently Nevada. As an industrial-grade hardware component, it is deployed specifically for the online condition monitoring and early fault warning of rotating machinery across power plants, petrochemical facilities, and other heavy industries, typically selected for machine environments with tight physical mounting spaces where a standard 8 mm probe is too large.

The 330173-03-08-05-02-05 acts as the terminal physical sensing node within a complete non-contact eddy current monitoring loop, typically selected for industrial machinery with tight mounting spaces. When integrated with a matching 3300 5 mm Proximitor Sensor and extension cable, the hardware loop utilizes the variations in the physical gap between the probe tip and the observed conductive surface to transmit a negative direct current voltage signal.
The physical construction delivers a stable, reliable signal output across wide temperature variations to safeguard critical industrial assets under continuous operations. Across the entire product line, the hardware components support complete physical interchangeability among the probes, extension cables, and Proximitor sensors to eliminate the need for individual part matching or manual bench calibration during field maintenance.

Thermal Power
Used for non-contact bearing vibration measurement on high-pressure boiler feed pumps to prevent boiler accidents caused by feedwater interruption.
Nuclear Power
Used for monitoring the differential expansion of the high-pressure cylinder in conventional island steam turbines, where reverse mounting greatly facilitates external calibration in confined spaces.
Hydroelectric Power
Used for monitoring oil film thickness and dynamic displacement of thrust bearings in hydroelectric turbine generators.
Large Steel Plants & Metallurgy
Used for rotor thrust trip protection in Blast Furnace Blowers to prevent severe collisions between rotating and stationary components.
Fertilizer & Ammonia Chemical Manufacturing
Used inside the bearing housings of syngas compressors, where the reverse-mount design shields the probe coil inside a sealed sleeve from direct erosion by corrosive process gases.
Cement & Building Materials Manufacturing
Used for fluid-film bearing monitoring of large exhaust ID fans in raw mills, utilizing the protective housing to prevent physical wear on probe cables from high onsite dust.
When utilizing this 5 mm small-diameter probe, field technicians must strictly verify the borehole depth and control the initial mechanical installation gap due to its constrained sensing coil size. Meanwhile, because of the extremely compact tip footprint, an adequate physical clearance span must be maintained between adjacent probes or surrounding metal walls to prevent cross-talk magnetic interference.
Given that its integrated 0.5-meter coaxial cable requires careful routing, the minimum physical bend radius must not be less than 25.4 mm during installation. When mating this short tail cable with the corresponding extension cable and Proximitor Sensor to form a 5-meter or 9-meter monitoring loop, the ClickLoc coaxial connector must be fully engaged and locked via manual finger-tightening.
Once secured, original protective heat-shrink sleeving should be applied to achieve a complete physical seal around the junction, isolating the physical signal path from the ingress of high-pressure oil mist, moisture, or highly corrosive condensing steam around the bearing housing.
This Bently Nevada 3300 series 5 mm proximity eddy current transducer probe assembly (Model: 330173-03-08-05-02-05) is a standardized hardware component manufactured specifically for tight physical installation spaces in industrial fields. Because certain heavy rotating machinery features a compact internal structure where standard 8 mm probes are often constrained by space limits, this 5 mm diameter tip configuration provides excellent geometric clearance and is primarily utilized to track online radial shaft vibration and axial thrust displacement. In terms of physical dimensions, the probe features an M8×1 metric threaded case with a 30 mm smooth unthreaded length, and an overall rigid metal case length of 80 mm for insertion into the bearing housing. Serving as the terminal sensing node within the complete non-contact monitoring chain, it is calibrated by default from the factory for AISI 4140 steel curves and comes equipped with an integrated 0.5-meter unarmored 75-ohm triaxial cable. This physical construction complies with the fundamental criteria of the American Petroleum Institute (API) 670 standard for mechanical configurations, holds multiple international hazardous area agency approvals (-05), and supports continuous operation across high-and-low temperature environments from -35°C to +177°C as well as in 100% condensing humidity. During practical field wiring, the short tail cable of the probe is physically mated with a corresponding extension cable and Proximitor Sensor via the factory gold-plated ClickLoc coaxial connector to form a complete 5-meter or 9-meter signal loop, enabling standardized plug-and-play component replacement in subsequent supply chain maintenance.
It is a 3300 XL 8 mm series proximity probe manufactured by Bently Nevada, specifically designed for reverse mount applications with a 3/8-24 UNF thread.
What does 330173-03-08-05-02-05 mainly measure?
It is used for non-contact shaft vibration (radial), axial displacement (thrust), Keyphasor (speed/phase), and differential expansion monitoring in large industrial rotating machinery.
How to correctly use and install the 330173-03-08-05-02-05 probe?
It must typically be used with a reverse mount probe housing or a specialized bracket. The probe is threaded in from the rear of the housing; once powered, the position is adjusted based on the gap voltage (e.g., -10 Vdc) before locking the housing.
Can 330173-03-08-05-02-05 work alone?
No. The probe only has an integral 0.5m cable. It must be connected to a 3300 XL extension cable and plugged into a 3300 XL Proximitor Sensor to form a complete system for voltage output.
Do I need to recalibrate the system when replacing the 330173-03-08-05-02-05 probe?
No. The Bently Nevada 3300 XL system features complete interchangeability, meaning replacing it with a probe of the same specs requires no manual bench calibration.
