Product Introduction
In demanding industrial environments, proximity sensor failures can cause costly downtime. The Bently Nevada 330708-00-24-10-11-00 3300 XL 11 mm Proximity Probe is engineered to withstand extreme conditions, offering superior reliability for critical vibration monitoring applications. This probe uses a polyphenylene sulfide (PPS) tip and AISI 304 stainless steel case, ensuring durability in harsh settings. With a temperature range of -52°C to +177°C, it handles both cryogenic and high-heat processes without performance degradation.

Industry Applications
This Bently Nevada 330708-00-24-10-11-00 probe excels in turbine, compressor, and pump monitoring. Its PPS tip resists chemical attack, while the stainless steel case withstands vibration and mechanical stress. In a petrochemical plant, the probe’s wide temperature range allows direct mounting on hot bearing housings. For steam turbines, the FluidLoc cable prevents moisture ingress, maintaining signal integrity even in condensing environments.
Installation & Setup Guidance
Mount the Bently Nevada 330708-00-24-10-11-00 probe with the 5/8-18 UNF thread into a properly tapped hole. Use the recommended torque of 15.2 N·m to avoid damaging the case. Ensure the cable bend radius does not exceed 25.4 mm. The ClickLoc connector requires only finger-tight torque (max 0.565 N·m). For armored versions, take care to avoid kinking the armor. Always verify the probe gap using the specified DC resistance check.
Maintenance & Reliability
Routine inspection of the probe tip and cable prevents failure. Check for contamination or physical damage on the PPS tip. The pressure seal, though robust, can degrade if exposed to temperatures below -34°C regularly. Replace the probe if the DC resistance drifts beyond the ±0.5 ohm tolerance. This Bently Nevada 330708-00-24-10-11-00 model’s design reduces total cost of ownership by extending service intervals and minimizing false alarms.
