Bently Nevada 3300 NSv Compact Probe: Space-Saving Sensor for Tight Spots

Meet the Bently Nevada 330903-00-06-05-02-CN. This is a short-case version of the reliable 3300 NSv proximity probe. Its compact 60 mm overall length is perfect for installations with limited space. The 330903-00-06-05-02-CN offers the same chemical resistance and performance as longer models but fits where others cannot.

Your Compact Probe Model Explained

The code 330903-00-06-05-02-CN details this probe's unique short design:

• 330903: Base model for a 3300 NSv probe with M8x1 metric thread, no armor.
• 00: Unthreaded Length: 0 mm. The full case is threaded.
• 06: Overall Case Length: 60 mm (Compact size).
• 05: Total Cable Length: 0.5 meter (20 inches).
• 02: Connector & Cable: Standard ClickLoc connector and cable.
• CN: Configuration: Manufactured to country-specific standards.

Frequently Asked Questions (FAQ)

What is the primary use for this short 60 mm case probe?

It is designed for space-limited installations where a standard-length probe would not fit, such as in compact machinery or between closely spaced components.

Is the performance different from the longer 120 mm NSv probe?

No. The sensing performance, linear range, output, and chemical resistance are identical. Only the physical case length is different to suit various mounting depths.

How do I ensure I don't over-torque the M8x1 thread during installation?

Use a calibrated torque wrench. The maximum torque is very low: 0.56 N•m (5 in•lb). This is slightly more than finger tight. Over-torquing will damage the probe.

Can I connect this 0.5m probe to a longer extension cable?

Yes. This probe is designed to be used with Bently Nevada extension cables to create standard 5-meter or 9-meter total system lengths for connection to the Proximitor.

Why is chemical resistance important for a proximity probe?

In process compressors and similar equipment, probes can be exposed to aggressive gases or lubricants. The NSv probe's materials resist degradation from these chemicals, ensuring long-term reliability.
