Industry Applications
The Bently Nevada 330708-00-24-10-01-05 excels in vibration monitoring for rotating machinery such as turbines, compressors, and pumps. Its robust sealing prevents fluid ingress, making it ideal for oil and gas, power generation, and manufacturing facilities. The probe’s PPS tip resists chemical attack, reducing failure risks in aggressive environments.
Installation Guidance
Proper installation ensures optimal performance. Use a 5/8-18 UNF thread engagement of no more than 0.938 inches. Tighten the probe case to 15.2 N·m (recommended) and avoid exceeding 45.2 N·m. The connector should be finger tight, with a maximum torque of 0.565 N·m. Maintain a minimum bend radius of 25.4 mm to prevent cable damage. Do not operate below -34°C as premature pressure seal failure may occur.
Maintenance and Reliability
Regularly inspect the cable for cuts or abrasions, especially near the connector. The probe’s Viton O-ring seal is effective but not pressure-tested before shipment; contact UBEST Automation if your application requires a pressure test. Store the probe within its temperature range (-51°C to +177°C) and avoid exposing it to temperatures below -34°C during operation to preserve seal integrity.
Selection Guide
Before purchasing, verify your required thread type (5/8-18 UNF, M16x1.5, or M14x1.5) and total length. The Bently Nevada 330708-00-24-10-01-05 is offered in 1, 5, or 9 meter cable lengths.
