Bently Nevada 330930-040-01-05 3300 NSv Extension Cable

Description

330930-040-01-05: 3300 NSv extension cable configured with a 4.0-meter cable length (Option 040), stainless steel armor with an FEP jacket (Option 01), and multiple agency approvals (Option 05). This cable connects a 3300 NSv proximity probe to a 3300 XL NSv Proximitor Sensor, completing the eddy-current measurement chain. It is used in situations with tight clearances and restricted target areas where standard proximity systems are physically too large.

This variant includes physical armor and FEP jacketing, which protects the internal coaxial line from physical abrasion, crushing, and exposure to corrosive chemicals or process fluids. The combination of a 4.0 m extension cable and a 1.0 m probe (or similar matching configurations) forms a standard 5.0 m system length. The integrated ClickLoc miniature coaxial connectors provide a secure, low-loss electrical connection that resists moisture ingress when properly sealed.

Features

• Option 040 specifies a 4.0-meter (13.1-foot) physical cable length.
• Option 01 integrates stainless steel armor with a protective FEP jacket for harsh industrial environments.
• Option 05 includes multiple international agency approvals for installation in hazardous areas.
• ClickLoc miniature coaxial connectors establish secure connections without requiring specialized torque tools.
• Extremely low electrical loss with 75-ohm characteristic impedance matching the 3300 XL NSv sensor system.

Applications

The 330930-040-01-05 extension cable is used in machinery protection systems for rotating equipment with limited target geometries. Typical applications include:

• Aeroderivative gas turbines
• Centrifugal and axial compressors with compact housings
• Small-bore machinery and high-speed pumps
• Fluid-film bearing radial vibration and axial position measurements

Installation Guidelines

When installing the 330930-040-01-05 extension cable, ensure the total physical length of the probe plus the extension cable matches the calibration length of the 3300 XL NSv Proximitor Sensor (typically 5.0 meters or 7.0 meters). Maintain a minimum bend radius of 25.4 mm (1.0 inch) to prevent physical or electrical degradation of the coaxial core. Protect the coaxial ClickLoc connectors from moisture, dirt, and process lubricants by using silicone self-fusing tape or dedicated connector protectors. Avoid routing extension cables adjacent to high-voltage conduits or high-power AC cables to minimize electromagnetic interference.
