Product Describe:
Bently Nevada 330930-060-00-05 is a 6.0 m extension cable for a 3300 XL NSv proximity-transducer system. The 00 cable option is supplied without stainless-steel armor.
Bently Nevada 330930-060-00-05 connects a remotely installed NSv probe to its matched signal-conditioning hardware where a longer cable run is needed.
Uses 75-ohm coaxial construction.
Insulates the cable with fluorinated ethylene propylene (FEP).
Provides a typical capacitance of 69.9 pF per metre.
Uses gold-plated brass connectors.
A 1.0 m NSv probe lead and this 6.0 m extension form a 7.0 m electrical path. The selected Proximitor system length must match that total; physical reach alone is not a sufficient basis for cable selection.
Important Notice: Protect the unarmored run at metal edges and secure both sides of each coaxial joint against cable pull.

Compressor probe routing
Extend an NSv probe connection from a confined compressor measurement point.
Seven-metre transducer chains
Pair with a 1.0 m probe lead and the correct 7.0 m signal conditioner.
Radial vibration channels
Carry the probe signal within a properly matched NSv vibration measurement chain.
Axial-position channels
Connect a compatible NSv probe used for thrust-position measurement.
Installation and service checks for Bently Nevada 330930-060-00-05.
1
Confirm that the probe and extension lengths total the selected system electrical length.
2
Use the NSv cable with the corresponding NSv probe and signal conditioner.
3
Maintain a bend radius of at least 25.4 mm along the route.
4
Provide routing protection appropriate to a cable without stainless-steel armor.
5
Keep mating coaxial contacts clean and dry before connection.
6
Tighten connectors by hand and do not exceed 0.56 N·m.
7
Prevent traction or twisting at the probe-to-extension connection.
8
Check the assembled channel response after routing and connection are complete.
Technical notes
Include the probe lead when calculating electrical length. A cable continuity result alone does not establish a correctly matched proximity-transducer channel.
Can Bently Nevada 330930-060-00-05 complete a 7.0 m transducer chain?
Yes. Its 6.0 m extension length combines with a 1.0 m probe lead to make a 7.0 m path, which must match the selected signal conditioner.
What bend limit applies when routing Bently Nevada 330930-060-00-05?
The minimum bend radius is 25.4 mm, so a tight fold or sharp turn is unsuitable.
Should the coaxial connectors on Bently Nevada 330930-060-00-05 be wrench-tightened?
The recommended connection is finger-tight, with a maximum connector torque of 0.56 N·m.
How does the construction of Bently Nevada 330930-060-00-05 affect mechanical protection?
The cable has FEP insulation but no stainless-steel armor, so its route must protect it from mechanical damage.
Which electrical values characterize Bently Nevada 330930-060-00-05?
The cable is 75-ohm coaxial, with typical capacitance of 69.9 pF/m, center-conductor resistance of 0.220 ohm/m and shield resistance of 0.066 ohm/m.
Does Bently Nevada 330930-060-00-05 itself convert the signal to 4-20 mA?
No. It is a passive extension cable; the matched signal-conditioning or transmitter hardware determines the system output.
What center-conductor resistance is calculated for the full length of Bently Nevada 330930-060-00-05?
Using 0.220 ohm/m over the 6.0 m cable gives 1.32 ohm before connector and test-lead contributions. This calculated cable-only value is not an additional acceptance tolerance.
Does the temperature capability of Bently Nevada 330930-060-00-05 set the limit for the entire measurement chain?
No. The extension cable has an operating range of -52 to +177 degrees C. The probe, connectors and signal conditioner must each remain within their own applicable limits; the cable rating alone does not qualify the complete installation.
