Bently Nevada 330930-060-04-05 3300 NSv Extension Cable

Description

330930-060-04-05 specifies a 6.0-meter 3300 NSv extension cable equipped with stainless steel armor, a protective FEP jacket, and an integrated connector protector. This specific option configuration provides physical defense and environmental shielding in tight-clearance industrial applications where smaller target sizes or compact mounting profiles restrict standard transducer installation. The cable connects a 3300 NSv proximity probe to a compatible 3300 XL NSv Proximitor Sensor to complete the non-contact displacement measurement loop.

Unlike standard unarmored configurations (Option 00) or unjacketed armored variants (Option 02), this cable uses a rugged fluorinated ethylene propylene (FEP) jacket over stainless steel armor to resist corrosive chemical exposure and mechanical abrasion. Additionally, the pre-installed fluorosilicone connector protector prevents moisture and fluid contamination at the critical probe-to-cable junction, while Option 05 approvals permit installation in hazardous areas.

Features

• Option 060 specifies a 6.0-meter (19.7 feet) total cable length, matching the required system calibration profile.
• Option 04 delivers integrated stainless steel armor with a protective FEP outer jacket to shield the internal coaxial line from physical damage and chemical deterioration.
• Fluorosilicone connector protector pre-installed on the female end prevents moisture, turbine oil, and debris ingress at the probe-to-cable connection point.
• Option 05 compliance provides multiple global hazardous area certifications for explosive environments.
• Coaxial 75 ohm FEP-insulated construction maintains constant impedance to avoid signal distortion across the measurement path.
• Miniature coaxial ClickLoc connectors ensure secure coupling with positive tactile engagement.

Applications

• Small-bore steam and gas turbines
• High-speed machinery with limited target geometry
• Aeroderivative gas turbines
• Centrifugal compressors and pumps with tight mechanical clearances
• Shaft vibration, axial position, and radial offset monitoring in hazardous process areas

Installation Guidelines

When installing the 3300 NSv extension cable, observe the following engineering practices:

• Do not exceed the minimum cable bend radius of 25.4 mm (1.0 in) to prevent internal damage or impedance changes in the coaxial core.
• Ensure the female connector on the extension cable is securely mated to the male connector of the proximity probe. Tighten connections to finger-tight, or a maximum of 0.56 N m (5 in lb) if using a torque wrench. Do not use pliers or other unrated tools.
• Position the pre-installed fluorosilicone connector protector over the mated connection to shield the electrical contacts from fluids, moisture, and particulate ingress. Avoid using silicone tape inside machine casings or where direct exposure to turbine oil is expected.
• Route the cable through dedicated conduit or cable trays to isolate it from electromagnetic interference (EMI) and physical hazards. Maintain physical separation from high-voltage AC power lines.
• Ensure the combined length of the proximity probe and the extension cable matches the calibrated total system length required by the 3300 XL NSv Proximitor Sensor (typically 5.0 meters or 7.0 meters).
