The 330708-00-10-90-02-00 probe is engineered for long-term reliability, featuring a Viton O-ring pressure seal and robust cable construction. Its differential pressure sealing capability helps prevent leakage between the tip and case, reducing maintenance needs.
Industry Applications
These proximity probes are essential for continuous monitoring of shaft vibration and axial position in turbines, compressors, pumps, and generators. The Bently Nevada 330708-00-10-90-02-00 excels in power generation, oil and gas, and petrochemical plants where unscheduled downtime is costly. With its wide temperature range and rugged construction, it performs reliably in harsh environments, from arctic cold to high-heat processes.
Installation & Setup Guidance
Proper installation ensures accurate readings. For the 330708-00-10-90-02-00, use the recommended torque of 15.2 N·m (133 in·lb) on the probe case (5/8-18 thread). Maximum engagement depth is 0.938 inches. The ClickLoc connector should be finger-tight with maximum torque of 0.565 N·m (5 in·lb). Cable bend radius must be at least 25.4 mm (1.0 inch) to prevent damage. Avoid exposing the probe to temperatures below -34°C (-30°F) repeatedly, as premature pressure seal failure may occur.
Maintenance & Reliability
The Bently Nevada 330708-00-10-90-02-00 is designed for minimal maintenance. The Viton O-ring pressure seal should be inspected periodically if the probe is used in high-differential-pressure applications. The stainless steel case and PPS tip resist corrosion and wear. Operate within -52°C to +177°C for optimal life. Regularly check cable connections and ensure the grounding path is intact to maintain signal integrity. This probe offers excellent total cost of ownership due to its robust construction and long service intervals.
Selection Guide
When selecting the Bently Nevada 330708-00-10-90-02-00, verify your required thread size (5/8-18 UNF), total cable length (9.0 m), and connector type (ClickLoc).
