The Bently Nevada 330707-00-20-10-11-00 is a member of the renowned 3300 XL series, widely trusted for machinery condition monitoring. This 11 mm proximity probe offers accurate, non-contact measurement of shaft vibration and axial position. Its sturdy construction guarantees stable performance across demanding industrial environments, including steam turbines and large compressors. Moreover, this model features a 1.0-meter cable length, making it ideal for installations with shorter routing distances.
The 3300 XL 11 mm Proximity Probe comes with a precise set of technical attributes. To begin with, the probe case thread is a 5/8-18 UNF type. The unthreaded length option is 0 inches, while the overall case length is 2.0 inches. The total length for model 330707-00-20-10-11-00 is 1.0 metre, which is approximately 3.3 feet. For connectivity, this unit uses a miniature coaxial ClickLoc connector with a connector protector, paired with FluidLoc cable for enhanced fluid resistance.
Specifically, the probe tip is manufactured from Polyphenylene sulfide (PPS), a material known for its thermal stability. Additionally, the probe case is made of AISI 304 stainless steel (SST), which provides excellent resistance to corrosion. Regarding the cable, it is a 75 Ω triaxial type with fluoroethylene propylene (FEP) insulation. Consequently, its DC resistance from the center conductor to the outer conductor measures 5.9 ± 0.5 ohms. The operating and storage temperature range is from -51°C to +177°C.
When handling this device, several mechanical limits are important to follow. For instance, the maximum rated probe case torque is 45.2 N•m (400 in•lb), while the recommended torque is 15.2 N•m (133 in•lb). The maximum length of thread engagement for this 5/8-18 UNF thread is 0.938 inches. Furthermore, the connector-to-connector torque should remain finger tight, with a maximum of 0.565 N•m (5 in•lb). The minimum bend radius for the cable is 25.4 mm (1.0 in), regardless of armor presence.
Proper installation of this probe requires attention to specific precautions. The 3300 XL 11 mm Probe uses a Viton O-ring to seal differential pressure between the probe tip and case. However, please note that these probes do not undergo pressure testing before shipment. Therefore, if your application demands a verified pressure seal, you will need to reach out to the custom design department. Also, exposing this probe to temperatures below -34°C (30°F) can lead to premature seal failure, so avoid such conditions during storage or operation.
