The Bently Nevada 330708-00-25-90-02-00 belongs to the established 3300 XL series, offering exceptional reliability for critical machinery protection. This 11 mm proximity probe provides accurate, non-contact measurement of vibration and position. Its robust design ensures consistent performance in a variety of industrial applications, from turbines to compressors. Furthermore, this model comes with a 9.0-meter total cable length.
The 3300 XL 11 mm Proximity Probe offers a comprehensive set of technical features. Firstly, the probe case thread is a 5/8-18 UNF type. Its unthreaded length option is 0 inches, with a case length of 2.5 inches. The total length for model 330708-00-25-90-02-00 is 9.0 meters, which is equivalent to 29.5 feet. The connector and cable-type option is a miniature coaxial ClickLoc connector with standard cable.
Specifically, the probe tip is constructed from Polyphenylene sulfide (PPS), providing excellent durability. Additionally, the probe case is made from AISI 304 stainless steel (SST), ensuring corrosion resistance. Regarding the cable, it is a 75 Ω triaxial type with fluoroethylene propylene (FEP) insulation. Therefore, its DC resistance from the center conductor to the outer conductor is 8.5 ± 1.1 ohms. The operating and storage temperature ranges from -51°C to +177°C.
When installing this device, certain mechanical parameters are crucial. For instance, the probe case torque maximum rating is 45.2 N•m (400 in•lb), while the recommended torque is 15.2 N•m (133 in•lb). It is also important to note the maximum length of thread engagement is 0.938 inches. Furthermore, the connector-to-connector torque should only be 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), whether with or without armor.
For a successful installation, you must observe specific procedures. The 3300 XL 11 mm Probe is designed to seal differential pressure between the tip and case using a Viton O-ring. However, be aware that these probes are not pressure tested before shipment. Consequently, for applications requiring a seal test, you must contact the custom design department. Additionally, exposing the probe to temperatures below -34°C (30°F) may cause premature failure of the pressure seal.
Your shipment will include the following:
1 x Bently Nevada 330708-00-25-90-02-00 Probe
1 x Miniature coaxial ClickLoc connector (pre-attached)
