Information
- In a matched 7 m NSv measurement chain, Bently Nevada 330930-060-03-05 carries the probe connection to the Proximitor Sensor while allowing the conditioner to be positioned away from the measurement point.
Connection protection: Connector protector included
Electrical construction: 75 ohm coaxial cable with FEP insulation
Cable capacitance is 69.9 pF/m typical. Center-conductor and shield resistance are 0.220 and 0.066 ohm/m respectively. Route the cable with a minimum bend radius of 25.4 mm and protect the coaxial junction against contamination.

System applications: The applications below describe the complete NSv transducer system. This extension cable connects the probe to the signal conditioner; measurement performance depends on the matched probe, cable and Proximitor Sensor combination.
7 m NSv measurement chain
Connect a 1.0 m NSv probe cable to the 7 m Proximitor Sensor using this 6.0 m extension.Confined measurement locations
Provide cable reach from a small-target or restricted-space NSv probe location to the conditioner mounting point.Radial vibration and position
Carry the probe connection in an NSv system used for radial vibration or radial position measurements.Axial position and speed reference
Support the electrical interconnection for an NSv system configured for axial position, speed or Keyphasor measurement.
Use a 1.0 m NSv probe cable with this 6.0 m extension and the matching 7 m Proximitor Sensor.
Support the cable, avoid abrasion and maintain at least 25.4 mm bend radius.
Keep coaxial contacts clean. Tighten finger tight and do not exceed 0.56 N·m.
Seat the protector over the connection and inspect it for tears or damage before returning the loop to service.
The extension cable range is -52 to +177 °C. Check the different probe and Proximitor limits at their own mounting locations.
After reconnection, verify probe gap, response to target movement and the receiving monitor indication before enabling machine protection.

Technical notes
Installation relationship: Pair the 6.0 m extension cable with a 1.0 m NSv probe cable and a 7.0 m 3300 XL NSv Proximitor Sensor. The combined cable length must match the sensor system length.
Connector and routing protection: Use smooth cable bends with a minimum 25.4 mm radius. Tighten the coaxial connection finger tight without exceeding 0.56 N·m, and fit the connector protector.

FAQ View All FAQ
-
Which probe-cable length pairs with 330930-060-03-05 in a 7 m NSv system?The 6.0 m extension cable pairs with a 1.0 m NSv probe cable to make a 7.0 m electrical length. The combined length must match the 7 m 3300 XL NSv Proximitor Sensor.
-
Does the 03 option on 330930-060-03-05 include armor or connector protection?Option 03 specifies cable without stainless steel armor and includes a connector protector. Support the unarmored cable along its route and seat the protector over the connector junction.
-
What electrical properties must a replacement for 330930-060-03-05 preserve?The NSv extension cable uses 75 ohm coaxial construction with FEP insulation and typical capacitance of 69.9 pF/m. Maintain the specified cable type and electrical length when replacing the assembly.
-
How tightly may 330930-060-03-05 be bent during routing?The minimum bend radius is 25.4 mm. Route the cable in smooth bends and provide clearance at connectors so the cable is not pinched or sharply folded.
-
How should the coaxial connectors on 330930-060-03-05 be tightened?The recommended connector-to-connector torque is finger tight; the maximum is 0.56 N·m. Keep the contacts clean and align the connector before engaging it.
-
What temperature range applies to 330930-060-03-05?The extension cable operating and storage range is -52 to +177 °C. The associated Proximitor Sensor has different temperature limits, so check each component against its installation location.
-
Which conductor resistance values apply when checking 330930-060-03-05?The extension cable center conductor has a DC resistance of 0.220 ohm/m and its shield has a DC resistance of 0.066 ohm/m. These are cable conductor values, distinct from the probe center-to-outer-conductor resistance.
-
What does the 05 approval suffix on 330930-060-03-05 select?The 05 suffix selects the multiple-approvals option. Apply the approval markings and installation requirements for the complete probe, extension cable and Proximitor Sensor system used at the site.
