Industry Applications
The Bently Nevada 330171-00-40-10-02-00 probe is ideal for upgrading vibration monitoring in turbines, compressors, and pumps. Its 5 mm sensing face and 1/4-28 thread allow direct replacement of older probes in existing mounting holes. The rugged construction withstands temperatures up to +177°C, making it suitable for steam turbine bearing housings and gearbox casings.
Installation & Setup Guidance
When drilling and tapping a mounting hole for this probe, use a #3 or larger tap drill to ensure proper thread engagement. Maximum thread engagement is 0.375 in. Apply the recommended torque of 5.1 N·m (45 in·lb) to secure the probe case; do not exceed 7.3 N·m (65 in·lb). The connector-to-connector torque should be limited to 0.565 N·m. Maintain a minimum cable bend radius of 25.4 mm to avoid damaging the FEP insulation.
Maintenance & Reliability
The probe is designed for long service life with its PPS tip and stainless steel case. Follow the temperature schedule for hazardous area classifications (EPL Ga, Gc, Dc) to avoid exceeding ambient limits. The probe's sensitivity to 60 Hz magnetic fields is minimal (0.0119 mV pp/gauss at 10 mil gap with XL Proximitor Sensor). Periodic inspection of the cable and connector is recommended, especially if the probe is exposed to vibration or extreme temperatures.
Selection Guide & Purchasing Advice
Before purchasing, verify that the 330171-00-40-10-02-00 probe matches your existing system requirements: thread size (1/4-28 UNF), total length (1.0 m), and connector type (Miniature coaxial ClickLoc).
