Industry Applications
The Bently Nevada 330707-20-30-10-01-05 is ideal for monitoring vibrations in compressors, turbines, pumps, and fans. Its 11 mm probe tip and 1-metre cable suit tight installations in critical rotating machinery. With multiple approvals, it meets global safety standards for process industries such as oil and gas, power generation, and petrochemical.
Installation & Setup Guidance
Proper mounting is critical for accurate readings. Use the 5/8-18 threaded case and observe the maximum thread engagement of 0.938 in. Apply the recommended 15.2 N·m torque to avoid damaging the probe case or distorting the measurement. Ensure the cable bend radius does not exceed 25.4 mm to prevent signal loss or cable fatigue. The ClickLoc connector provides a secure, quick-connect interface; torque the connector only to finger tight (max 0.565 N·m).
Maintenance & Reliability
The probe’s PPS tip and 304 stainless steel case resist corrosion and wear. The Viton O-ring seals the differential pressure between tip and case, but probes are not pressure-tested before shipment. Avoid exposing the probe to temperatures below -34°C for extended periods, as this may compromise the pressure seal. Regular inspection of the cable and connector for damage helps maintain signal integrity.
Selection Guide & Purchasing Advice
When ordering the Bently Nevada 330707-20-30-10-01-05, verify the total probe length (1, 5, or 9 metres) and thread type (5/8-18 UNF) match your application. For custom pressure seal testing or special dimensions, contact the manufacturer.
