Product Introduction
In critical rotating machinery, accurate vibration monitoring is essential to prevent catastrophic failures. The Bently Nevada 330172-00-12-10-01-CN provides reliable proximity sensing with its 5mm probe design. This industrial automation module features a PPS tip and AISI 304 stainless steel case, built for durability in harsh environments. The probe includes armor for added protection and uses a 1/4-28 UNF thread for secure mounting.
Technical Specifications
The Bently Nevada 330172-00-12-10-01-CN operates with a -17.5 Vdc to -26 Vdc power supply at 12 mA maximum consumption. It has a sensitivity of less than 2 mV change per volt change in input voltage and an output resistance of 50 W. The probe DC resistance for the 1.0 m length is 7.59 ± 0.50 Ω. The probe temperature range is -35°C to +177°C. The probe cable is 75 Ω triaxial FEP insulated, and the connector is a miniature coaxial ClickLoc with connector protector.

Application Scenarios
The Bently Nevada 330172-00-12-10-01-CN is ideal for monitoring shaft vibration in turbines, compressors, and large pumps. Its armored construction withstands high vibration and mechanical stress. The PPS tip provides excellent resistance to chemicals and abrasion. Use it in steam turbines, gas compressors, and centrifugal pumps to detect early signs of imbalance or misalignment.
Installation & Setup Guidance
When installing the 330172-00-12-10-01-CN, use a #3 or larger tap drill for the 1/4-28 threaded hole. Apply a recommended torque of 5.1 N·m (45 in·lb) to the probe case, not exceeding 7.3 N·m (65 in·lb). The maximum length of thread engagement is 0.375 in. Ensure the cable bend radius stays above 25.4 mm (1.0 in) to prevent damage. The connector torque should be no more than 0.565 N·m (0.42 ft·lbf).
Maintenance & Reliability
The probe operates across a broad temperature range from -35°C to +177°C. Avoid exposing the probe to temperatures below –34°C as it may cause premature failure of the pressure seal. Magnetic fields up to 300 Gauss at 60 Hz can affect output, but the probe shows minimal induced voltage at typical gaps. Regularly inspect the cable and connector for wear.
Selection Guide & Purchasing Advice
Before purchasing, verify that the unthreaded length (0 in), overall case length (1.2 in), total length (1.0 m), and connector type (miniature coaxial ClickLoc) match your system requirements. This version includes country-specific approvals (CN). For genuine Bently Nevada parts, choose PLC Source PRO as your trusted supplier.
