Product Overview: The 330171-00-08-90-01-05 Proximity Probe
In an era of increasingly demanding industrial machinery, the evolution from periodic manual inspections to continuous, high-fidelity condition monitoring has been driven by the need for engineering-grade precision. The Bently Nevada 330171-00-08-90-01-05 3300 5mm Probe represents this evolution, delivering exact measurement for critical turbomachinery applications. This probe, part of the renowned 3300 series, features a 1/4-28 UNF thread and a 9.0-meter total length, making it suitable for extended reach installations. Its miniature coaxial ClickLoc connector with protector ensures a secure, reliable connection in harsh environments. With multiple agency approvals, this probe is engineered for global deployment.
Technical Specifications and Performance
The 330171-00-08-90-01-05 operates with a -17.5 Vdc to -26 Vdc power supply, drawing a maximum of 12 mA. It provides a 50 Ω output resistance and maintains a sensitivity change of less than 2 mV per volt change in input voltage. The probe's DC resistance from center conductor to outer conductor is 9.87 ± 0.90 Ω at 9.0 meters. Constructed with a polyphenylene sulfide (PPS) tip and AISI 304 stainless steel case, it withstands temperatures from -35°C to +177°C. The 75 Ω triaxial FEP-insulated cable ensures signal integrity. For detailed electrical characteristics, refer to the official datasheet.
Key Features
- 5mm probe diameter with 1/4-28 UNF thread for standard mounting.
- 9.0-meter total length for remote monitoring installations.
- Miniature coaxial ClickLoc connector with protector for secure connections.
- Multiple agency approvals for global compliance.
- Polyphenylene sulfide (PPS) tip for chemical and thermal resistance.
- AISI 304 stainless steel case for durability.
- Operating temperature range: -35°C to +177°C.
Applications and Use Cases
This probe is ideal for continuous vibration monitoring on steam turbines, compressors, and pumps. In power generation, it detects shaft displacement and eccentricity, preventing catastrophic failures. For oil and gas, it monitors critical rotating equipment in remote locations. Additionally, its multiple approvals allow use in hazardous areas. The 9.0-meter length facilitates installation in confined spaces where the proximitor can be mounted away from extreme temperatures.
Installation and Setup
When drilling and tapping a mounting hole for a 1/4-28 probe, a #3 or larger tap drill is recommended. The maximum thread engagement is 0.375 inches. 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). For connector-to-connector torque, refer to the official table. Maintain a minimum cable bend radius of 25.4 mm (1.0 in) to avoid damage. Ensure the target is AISI 4140 steel for specified performance.
Maintenance and Reliability
Periodic inspection of the probe tip and cable is essential. Check for wear, contamination, or mechanical damage. Verify the gap voltage remains within linear range. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature seal failure. The robust construction ensures long service life, reducing downtime and maintenance costs.
