Product Overview
With a 1.0 metre total length, 20 mm overall case length, and 0 mm unthreaded length, the Bently Nevada 330173-00-02-10-02-CN delivers precise shaft displacement readings in tight industrial spaces. This 3300 series 5mm probe uses an M8 x 1 thread without armor and is made in the U.S.A. Its rugged construction, including an AISI 304 stainless steel case and a polyphenylene sulfide (PPS) probe tip, minimizes lifecycle cost by reducing probe failures and extending maintenance intervals.
Technical Specifications
Unless otherwise noted, the Bently Nevada 330173-00-02-10-02-CN specifications apply for a proximity transducer system at +18°C to +27°C with a -24 Vdc supply, a 10 kW load, an AISI 4140 steel target, and a probe gap of 1.27 mm (50 mils).

Performance and Durability
The 330173-00-02-10-02-CN uses a 75 Ω triaxial FEP cable for stable signal transmission over its 1.0 m length. The 7.59 ± 0.50 Ω DC resistance from the center conductor to the outer conductor matches the monitor input and helps ensure accurate readings. Gold-plated brass or gold-plated beryllium copper connectors resist corrosion, reducing the risk of intermittent faults in harsh environments.
Industrial Applications
Commonly used for vibration and axial position monitoring on rotating machinery, this Bently Nevada 330173-00-02-10-02-CN probe suits turbines, compressors, and pumps. With an operating temperature range from -35°C to +177°C, it can tolerate demanding process areas. By providing continuous displacement data, the probe enables predictive maintenance that prevents unplanned downtime and drives long-term cost savings.
Installation and Setup
Use the M8 x 1 thread to mount the probe, keeping thread engagement at or below 12 mm. Torque the probe case to 5.1 N·m recommended and never exceed 7.3 N·m. Secure the standard cable with the miniature coaxial ClickLoc connector, and apply no more than 0.565 N·m connector torque. Maintain a minimum cable bend radius of 25.4 mm to protect the FEP insulation. For calibration, the system often uses a 1.27 mm gap against an AISI 4140 steel target.
Reliability and Maintenance
The Bently Nevada 330173-00-02-10-02-CN is built for long service life. Its stainless steel case, PPS tip, and gold-plated connectors require only periodic visual inspection. Check cables for sharp bends or abrasion, and confirm that connector torque stays within the specified limit. These simple actions reduce maintenance costs and maximize asset availability.
Selection Guide
Before ordering, verify the exact part number 330173-00-02-10-02-CN. This configuration includes a 1.0 m total length, 20 mm case length, 0 mm unthreaded length, and a ClickLoc connector. Confirm the thread size M8 x 1 and the required cable length for your system. PLC Source PRO stocks genuine Bently Nevada 330173-00-02-10-02-CN probes and can support your replacement planning.
