330709-050-120-10-02-00 | Bently Nevada 11 mm Probe 1.0 m

The Bently Nevada 330709-050-120-10-02-00 is a Probe for industrial control and automation applications.

Bently Nevada 330709-050-120-10-02-00 is a 3300 XL 11 mm proximity probe built for precise shaft vibration and position measurement in rotating machinery. This model uses an M16 x 1.5 threaded case without armor, a 50 mm unthreaded length, and a 120 mm overall case length. The 1.0 metre total length and miniature coaxial ClickLoc connector support straightforward installation in tight machine housings.

Key Specifications of the 330709-050-120-10-02-00

• Probe dc resistance: 5.9 ± 0.5 ohms from center conductor to outer conductor
• Probe tip material: Polyphenylene sulfide (PPS)
• Probe case material: AISI 304 stainless steel (SST)
• Probe cable: 75 Ω triaxial, FEP-insulated
• Probe case torque: Maximum rated 63.3 N•m (560 in•lb); recommended 21.1 N•m (187 in•lb)
• Minimum bend radius: 25.4 mm (1.0 in) with or without SST armor
• Operating temperature: -52°C to +177°C (-62°F to +351°F)
• Storage temperature: -52°C to +105°C (-62°F to +221°F)

How Does the 3300 XL 11 mm Probe Support Reliability?

For maintenance engineers, This unit offers stable performance in harsh conditions. The PPS probe tip and AISI 304 stainless steel case resist wear and corrosion. The 75 Ω triaxial FEP cable maintains signal integrity over the 1.0 metre length. The probe seals differential pressure between tip and case with a Viton O-ring, though it is not pressure tested prior to shipment. This design suits continuous monitoring on compressors, pumps, and motors where early fault detection prevents unplanned downtime.

Installation and Maintenance Notes

Mount the probe using the M16 x 1.5 thread, observing the recommended torque of 21.1 N•m (187 in•lb). The maximum thread engagement is 24 mm. Keep cable bends above the 25.4 mm minimum radius to avoid damage. The ClickLoc connector requires only finger-tight torque, with a maximum of 0.565 N•m (5 in•lb). Protect connectors from moisture; the probe is rated for 100% condensing humidity when connectors are protected. For cross-talk limitation, a flat target should be at least 30.5 mm (1.2 in) in diameter, and shaft diameter should be at least 152 mm (6.0 in).
