The 330172-00-30-10-02-00 requires a supply voltage within the range noted. Operation above -23.5 Vdc reduces linear range. These specifications are based on a system with -24 Vdc supply, 10 kW load, AISI 4140 steel target, and 1.27 mm gap.
Industry Applications
This Bently Nevada 330172-00-30-10-02-00 is ideal for vibration monitoring in steam turbines, centrifugal compressors, and large pumps. Its rugged construction withstands harsh environments, and the PPS tip provides excellent insulation. The 1/4-28 UNF thread ensures simple mounting in standard tapped holes. Apply this probe wherever precise shaft displacement measurement is required.
Installation & Setup Guidance
Proper mounting is critical for accurate readings. The probe case thread is 1/4-28 with a maximum thread engagement of 0.375 inches. Use a #3 or larger tap drill for the mounting hole. Recommended probe case torque is 5.1 N·m (45 in·lb), with a maximum of 7.3 N·m (65 in·lb). The connector-to-connector torque should not exceed 0.565 N·m (0.42 ft·lbf). Ensure the cable bend radius stays above 25.4 mm (1.0 inch) to avoid damage.
Maintenance & Reliability
Regularly inspect the probe cable and connector for signs of wear or corrosion. The gold-plated brass or beryllium copper connectors maintain low resistance. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent pressure seal failure. The 222 N (50 lbf) tensile strength at both the probe case and connector ensures secure connections. Following the temperature classification schedule (T1 to T5) helps maximize reliability in hazardous areas.
Selection Guide & Purchasing Advice
When ordering a replacement, verify the exact configuration: unthreaded length 00 (0 in), overall case length 30 (3 in), total length 10 (1.0 metre), connector option 02 (Miniature coaxial ClickLoc), and agency approval 00 (not required).
