Key Features & Benefits

• Extended Reach: The 7.0-meter integrated cable eliminates the need for separate extension cables in long-distance applications.
• Compact Design: Short 1.5-inch case ideal for installations with severe space constraints around the measurement point.
• Rugged Construction: Durable PPS tip and stainless steel case ensure longevity in industrial environments.
• Standard Compatibility: 3/8-24 UNF thread and ClickLoc connector ensure easy integration with common mounting holes and Bently Nevada systems.
• Reliable Connection: ClickLoc connector provides a secure, vibration-resistant electrical connection.

Compatibility & Installation Notes

This probe is designed for use with Bently Nevada 3300 NSv and compatible monitoring systems for non-safety (vibration) applications. Mount it directly into a standard 3/8-24 UNF threaded hole. The entire case is threaded, simplifying installation. Adhere to the recommended 11.3 N•m (100 in•lb) torque setting to avoid damage. The long cable allows direct routing to a distant junction box or monitor, reducing connection points.

Certifications & Ratings

• Approvals: Carries multiple international approvals (as indicated by option code 05).
• Environmental Sealing: Viton® O-ring provides a seal against differential pressure and contaminants.

Professional FAQs

What is the primary use for a 7-meter probe cable?

It is used when the monitoring rack or junction box is located far from the machine measurement point. This long integrated cable often removes the need for a separate extension cable.

What does "NSv" stand for and imply?

It stands for "Non-Safety, vibration." This probe is designed for continuous condition monitoring, not for critical machinery protection (trip) functions.

Can I use this 3300 NSv probe with a 3300 XL system?

Yes, 3300 NSv probes are electrically and mechanically compatible with 3300 XL system proximitors and monitors for vibration monitoring.

Why is the probe resistance lower for this 7m model?

The resistance specification is for the entire probe coil and cable loop. The value differs from shorter probes (like 1m) but is normalized by the system electronics.

What is the maximum thread engagement for this probe?

For a 3/8-24 UNF thread, do not engage more than 0.563 inches (approx. 14.3 mm) of threads to avoid damaging the probe tip or seal.
