Bently Nevada 330930-045-02-00 3300 NSv Extension Cable

Description

Option 045 (4.5 m length) and Option 02 (unjacketed stainless steel armor) specify this 3300 NSv extension cable — 330930-045-02-00. This cable connects a 3300 NSv proximity probe to a 3300 XL NSv Proximitor Sensor, completing the eddy-current measurement loop. It maintains impedance matching and signal integrity in transducer systems with restricted target areas or tight installations where standard probes cannot be used.

Unlike non-armored alternatives or configurations with FEP outer jackets, this specific cable features uncoated stainless steel armor to shield the internal coaxial line from physical damage, cuts, and mechanical wear. The total physical length of 4.5 meters, when combined with a compatible 0.5-meter probe, creates a standard 5.0-meter system length calibrated for small-bore machinery monitoring.

Features

• Option 045 specifies a 4.5-meter (14.8 feet) total cable length.
• Option 02 features stainless steel armor protection without an external FEP jacket.
• Option 00 indicates that agency approvals are not required for this configuration.
• Impedance-matched 75-ohm coaxial cable design minimizes electrical signal attenuation.
• ClickLoc coaxial connectors ensure secure physical attachment without threading.
• Minimum bend radius of 25.4 mm (1.0 in) allows routing through narrow conduits.

Applications

This extension cable is used in:

• Aeroderivative gas turbines with restricted envelope clearances
• Small-bore machinery and high-speed centrifuges with limited target geometry
• Centrifugal compressors and radial bearings requiring high-frequency response in tight spaces
• Industrial rotating machinery protection systems requiring non-contact displacement monitoring

Installation Guidelines

Connectors should be kept clean and dry during installation. A minimum bend radius of 25.4 mm (1.0 in) must be maintained to avoid internal conductor damage. Keep the total length of the extension cable and probe matched to the calibration length required by the Proximitor Sensor (e.g., 5.0 meters total system length).
