Bently Nevada 330709-016-240-50-02-00 5.0 m Probe

The Bently Nevada 330709-016-240-50-02-00 is a Probe for industrial control and automation applications.

Bently Nevada 330709-016-240-50-02-00 is a 3300 XL 11 mm proximity probe built for precise shaft displacement measurement in rotating machinery. Its 5.0 m total length pairs only with the five meter Proximitor Sensor, so system matching is fixed at the design stage.

What defines the 330709-016-240-50-02-00 probe?

The probe uses an M16 x 1.5 case thread with a 16 mm unthreaded length and a 240 mm overall case length. A miniature coaxial ClickLoc connector terminates the standard cable. The probe tip is polyphenylene sulfide (PPS), while the case is AISI 304 stainless steel. Agency approval is not required for this configuration.

Key technical parameters

• Probe dc resistance: 7.2 ± 0.8 ohms from center conductor to outer conductor.
• Probe case torque: maximum rated 63.3 N•m (560 in•lb); recommended 21.1 N•m (187 in•lb).
• Connector torque: finger tight recommended; maximum 0.565 N•m (5 in•lb).
• Minimum bend radius: 25.4 mm (1.0 in) with or without SST armor.
• Temperature range: operating and storage -52°C to +177°C (-62°F to +351°F).
• Cable: 75 Ω triaxial, FEP insulated.

How does the 5.0 m length affect system integration?

Five meter probes are designed for use with the five meter Proximitor Sensor only. This fixed pairing simplifies spare-parts planning because the probe and sensor must be ordered as a matched set. The ClickLoc connector provides a secure, tool-free connection. For cross-talk limitation, a flat target should be at least 30.5 mm (1.2 in) in diameter, and a shaft should be at least 152 mm (6.0 in) in diameter.

Installation and reliability notes

Respect the recommended case torque of 21.1 N•m (187 in•lb) to avoid damaging the M16 x 1.5 thread. Keep cable bends above the 25.4 mm (1.0 in) minimum radius. The probe seals differential pressure with a Viton O-ring, but it is not pressure tested before shipment. Exposing the probe to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal.
