Installation Guidance
For proper installation of the 330172-00-32-05-01-CN, ensure a clean mounting hole tapped with a #3 or larger drill. The maximum thread engagement is 0.375 in. Apply a torque of 5.1 N·m (45 in·lb) recommended, not exceeding 7.3 N·m (65 in·lb). The connector-to-connector torque should not exceed 0.565 N·m. Avoid bending the cable to a radius smaller than 25.4 mm (1.0 in).
Maintenance and Reliability
The probe operates reliably in ambient temperatures from -35°C to +177°C. Exposing to below -34°C may damage the pressure seal. The PPS tip and stainless steel case resist corrosion. For consistent measurements, maintain a target gap of 1.27 mm (50 mils) and use a -24 Vdc supply with a 10 kΩ load. The 330172-00-32-05-01-CN, when paired with a Bently Nevada XL Proximitor, offers low sensitivity to 60 Hz magnetic fields (0.0014 mil pp/gauss at 50 mil gap).
Applications
This probe is suitable for monitoring shaft vibration and position in rotating machinery such as turbines, compressors, and pumps. The armored design protects in harsh environments, making the 330172-00-32-05-01-CN ideal for continuous duty in oil and gas, power generation, and petrochemical facilities.
Selection Guide
When ordering the Bently Nevada 330172-00-32-05-01-CN, verify the total length (0.5 meter) and connector type. PLC Source PRO supplies genuine parts backed by availability. Confirm compatibility with your monitor or proximitor system before purchase.
