Product Overview
When monitoring critical rotating machinery, the Bently Nevada 330172-00-94-10-02-00 proves essential. This 3300 5mm probe with 1/4-28 UNF thread and protective armor delivers precise displacement measurements. Manufactured in the USA, this probe is part of the trusted 3300 series. It features a polyphenylene sulfide (PPS) tip and AISI 304 stainless steel case for durability in harsh environments.
Technical Specifications
The 330172-00-94-10-02-00 operates within a power range of -17.5 Vdc to -26 Vdc at 12 mA maximum consumption. Its output resistance is 50 W. The probe DC resistance from center conductor to outer conductor is 7.59 ± 0.50 Ω for the 1.0-meter length. Sensitivity is less than 2 mV change in output voltage per volt change in input voltage.

Additional features include a PPS tip material, AISI 303/304 stainless steel case, and 75 Ω triaxial FEP cable in 0.5, 1, 2, 5, or 9 meter lengths. Tensile strength is 222 N for both probe case to lead and lead to extension cable connectors.
Industry Applications
The 330172-00-94-10-02-00 excels in vibration monitoring for gas turbines, steam turbines, compressors, and pumps. With its ability to withstand 60 Hz magnetic fields up to 300 Gauss (5 meter system), it maintains accuracy even in electrically noisy environments. The probe's temperature schedule allows use across a wide ambient range, from -55°C to +232°C depending on temperature classification.
Installation and Mounting
Install the Bently Nevada 330172-00-94-10-02-00 using a 1/4-28 thread with a #3 or larger tap drill. The maximum thread engagement is 0.375 in. Apply probe case torque between 5.1 N·m (recommended) and 7.3 N·m (maximum). Use the miniature coaxial ClickLoc connector for cable attachment, tightening to a maximum torque of 0.565 N·m. Avoid cable bends tighter than 25.4 mm.
Maintenance and Reliability
Operating within -35°C to +177°C, the probe must not be exposed below -34°C to prevent pressure seal failure. The PPS tip resists chemicals and wear. Regularly inspect the armor and cable for damage. Follow the temperature schedule for hazardous area compliance: for EPL Ga and Gc, temperature classification T1 covers -55°C to +232°C, while T5 covers -55°C to +40°C.
Selection Guide
When ordering, verify the total length option: for this model, the probe length is 1.0 meter (3.3 feet) with 0 in unthreaded length and 9.4 in overall case length. Ensure your system supports the -24 Vdc supply and 10 kW load conditions for optimal performance. For genuine Bently Nevada 330172-00-94-10-02-00 probes, trust PLC Source PRO as a reliable supplier.
