Product Precautions
Bently Nevada 330730-080-00-00 supplies the eight-metre coaxial section in a nine-metre 3300 XL 11 mm transducer system. The standard unarmored construction is intended to pair with a one-metre probe and the corresponding nine-metre conditioner.
- Adds eight metres between a one-metre 11 mm probe and nine-metre conditioner.
- Uses the standard unarmored cable execution.
- Omits connector protectors through cable option 00.
- Retains separate core and jacket resistance values for continuity checks.
The extension sets the electrical length between the 11 mm probe and Proximitor. Its unarmored standard construction needs supported routing and separately selected environmental protection for both coaxial junctions.
Important Notice: Use the cable only in a matched nine-metre 3300 XL 11 mm chain. Standard option 00 does not provide armor, connector protectors or an agency approval.

Bently Nevada 330730-080-00-00 Official Technical Reference (PDF)Bently Nevada 330730-080-00-00 Installation & Commissioning Guide (PDF)
The Technical Reference organizes the exact ordering identity, applicable characteristics and system boundary for this 11 mm extension cable. The Installation & Commissioning Guide covers identification, pre-installation checks, connections, functional verification and the acceptance record.
Nine-metre 11 mm channels
Complete the long electrical chain used for extended-range proximity measurement.
Large-shaft vibration
Carry the probe signal for relative vibration measurements with the matched system.
Thrust and position
Support static displacement channels across the 11 mm system's rated range.
Cable service checks
Verify core and jacket continuity before reconnecting the probe and conditioner.
Apply these checks to the exact Bently Nevada 330730-080-00-00 item before returning its monitoring path to service.
1
Pair the 8 m extension with a 1 m 11 mm probe and a 9 m Proximitor.
2
Support the unarmored route and maintain at least the 25.4 mm bend radius.
3
Provide separate protection for both coaxial junctions because option 00 includes no protectors.
4
Keep connectors clean, electrically insulated and finger tight.
5
Disconnect the cable before measuring core and jacket resistance paths.
6
Do not apply the 8 mm system's scale factor or range to this 11 mm channel.
7
Review the -52 to +177 deg C cable limit at the actual route.
8
Confirm static gap and dynamic response after restoring the complete channel.
Technical notes
Use the cable only in a matched nine-metre 3300 XL 11 mm chain. Standard option 00 does not provide armor, connector protectors or an agency approval.
FAQ View All FAQ
-
Which chain is completed by 330730-080-00-00?A 1 m 3300 XL 11 mm probe plus this 8 m extension completes the 9 m sensor calibration.
-
Does 330730-080-00-00 include stainless-steel armor?No. Cable option 00 is the standard unarmored execution.
-
Are connector protectors supplied with 330730-080-00-00?No. Protector-equipped standard cable uses option 02.
-
What resistance values can be checked on 330730-080-00-00?The 8 m cable has a 2.0 +/-0.5 ohm core path and a 0.6 +/-0.2 ohm outer-conductor path.
-
Which scale factor belongs to the matched system using 330730-080-00-00?The 11 mm system uses 3.94 V/mm (100 mV/mil) under the stated operating conditions.
-
Can 330730-080-00-00 be used in a five-metre channel?No. Its eight-metre length is intended for the nine-metre system with a one-metre probe.
-
What target basis should be retained with 330730-080-00-00?The matched-system data uses an AISI 4140 steel target at least 31 mm in diameter.
-
What finishes acceptance after installing 330730-080-00-00?Record the full component chain, continuity checks, static gap and the expected monitor response.
