Product Overview
When monitoring rotating machinery, reliable vibration data is critical. The Bently Nevada 330171-00-16-90-01-05 5mm Probe delivers precise proximity measurement for shaft vibration and position monitoring. This 3300 series probe features a 1/4-28 UNF thread, a 9.0 meter cable, and a miniature coaxial ClickLoc connector with connector protector. Manufactured in the U.S.A., it uses a polyphenylene sulfide (PPS) tip and AISI 304 stainless steel case for durability.
Technical Specifications
The Bently Nevada 330171-00-16-90-01-05 operates with a power supply of -17.5 Vdc to -26 Vdc at 12 mA maximum consumption. Its supply sensitivity is less than 2 mV change per volt change, and output resistance is 50 Ω. For a 9.0 meter probe, DC resistance from center to outer conductor is 9.87 ± 0.90 Ω. Key specifications include:
-
Probe Tip Material: Polyphenylene sulfide (PPS)
-
Probe Case Material: AISI 304 stainless steel
-
Probe Cable: 75 Ω triaxial, FEP insulated, 9.0 meters
-
Tensile Strength: 222 N (50 lbf) probe case to lead
-
Probe Case Torque: 5.1 N·m recommended, 7.3 N·m maximum
-
Connector-to-Connector Torque: 0.565 N·m maximum
-
Minimum Cable Bend Radius: 25.4 mm
-
Probe Temperature Range: -35°C to +177°C
Thread engagement limits: probe case thread 1/4-28, maximum length of thread engagement 0.375 in. When drilling and tapping a mounting hole, a #3 or larger tap drill is recommended.
Applications & Use Cases
The Bently Nevada 330171-00-16-90-01-05 is designed for vibration monitoring in critical rotating equipment such as turbines, compressors, and pumps. It measures shaft radial vibration and axial position with high accuracy. The 9.0 meter cable allows flexible installation in industrial environments. Its rugged construction withstands harsh conditions, ensuring reliable data for predictive maintenance programs.
Installation & Setup Guidance
Proper installation of the Bently Nevada 330171-00-16-90-01-05 ensures optimal performance. Drill and tap a mounting hole for the 1/4-28 thread using a #3 or larger tap drill. The probe case torque should be between 5.1 N·m (recommended) and 7.3 N·m (maximum). For the connector, apply a maximum torque of 0.565 N·m. Avoid exposing the probe to temperatures below -34°C to prevent premature failure of the pressure seal. The cable bend radius must not be less than 25.4 mm to avoid damage.
Troubleshooting & Common Issues
Common issues with the Bently Nevada 330171-00-16-90-01-05 include magnetic field interference and improper thread engagement. At 60 Hz magnetic fields up to 300 Gauss, output voltage varies with gap; for example, at 50 mil gap the XL Proximitor Sensor output is 0.0131 mil pp/gauss. Ensure the probe is gapped correctly (1.27 mm typical) and that the target is AISI 4140 steel for standard calibration. If readings are erratic, check cable connections and torque values. For temperature extremes, refer to the temperature schedule for EPL Ga, Gc, and Dc classifications.
