This armored extension cable is designed for 3300 NSv proximity transducer systems used in centrifugal air compressors, refrigeration compressors, and process gas compressors where tight installation clearances, small shaft diameters, or harsh environments require superior cable protection and reliable signal integrity for vibration, position, and Keyphasor measurements.
Specific Application
Bridging structural connection gaps between an internal machine-mounted 3300 NSv proximity probe and a distant panel monitor rack.
Coaxial signal transmission paths on wet refrigeration compressors where regular exposure to spray fluids demands a moisture-sealed cable boot block.
Asset monitoring runs routed through harsh machinery paths that present severe physical wire cutting or abrasive tearing risks.

Installation & Troubleshooting FAQ
Q1: What structural installation requirement must be checked regarding system lengths before connecting this cable?
A: You must always verify that the physical length of your chosen 3300 NSv probe loop and this extension cable, when added together, exactly match the total rated length calibration profile marked on your 3300 XL NSv Proximitor Sensor. Mixing up mismatched hardware lengths alters the loop capacitance metrics, causing severe output calibration drift across your straight-line response curve.
Q2: Can I apply the provided self-fusing silicone tape to wrap this armored junction inside a gas turbine frame?
A: No, deploying self-fusing silicone tape inside a machine housing path where the connection comes into direct contact with continuous turbine oil washdowns is highly discouraged. Turbine oil will degrade the underlying silicone compound over time, compromising your electrical isolation parameters and triggering open-circuit signal drops.
Q3: What is the maximum allowable layout stretch distance from the Proximitor block to the monitor module room?
A: You can build out your continuous field wiring network up to an absolute maximum length configuration limit of 305 meters (1,000 feet) between the 3300 XL NSv Proximitor unit and your terminal monitoring tool. Exceeding this boundary range triggers localized high-frequency electrical signal rolloff and degradation, shifting your system linearity tolerances.
