Bently Nevada 330730-080-03-05 3300 XL 11 mm Extension Cable

Description

Option 080 (8.0 meters length), Option 03 (armored cable with connector protector), and Option 05 (multiple agency approvals) specify the configuration of this 3300 XL 11 mm Extension Cable — 330730-080-03-05.

This cable configuration features an integrated FEP-coated stainless steel armor jacket that provides physical protection in abrasive industrial environments. The miniature coaxial ClickLoc connectors are equipped with fluorosilicone connector protectors to shield the electrical connection from moisture, dust, and turbine oil. Operating as an electrical bridge within the 3300 XL 11 mm transducer system, it provides a precise 75 ohm coaxial pathway for high-frequency signal transmission between the proximity probe and the Proximitor sensor.

Features

• 8.0 Meter Length: Designed specifically to achieve the proper calibration distance within 9.0 meter system configurations when paired with a 1.0 meter proximity probe.
• FEP-Coated Armor: Covered in a stainless steel armor jacket with a protective FEP outer wrap to resist mechanical wear and physical impact.
• Connector Protectors: Pre-installed fluorosilicone boots guard male and female connections against fluid ingress and accidental disconnects.
• Standard Coaxial Design: Features a nominal 75 ohm characteristic impedance to maintain signal integrity without attenuation or phase distortion.
• Hazardous Area Rating: Configured with multiple global approvals suitable for deployment in zones requiring intrinsic safety or non-incendive parameters.

Applications

• Turbine and compressor shaft vibration and axial position monitoring.
• Ramp differential expansion measurements on industrial steam turbines.
• Rod position or rod drop detection on reciprocating compressors.
• Tachometer, phase reference (Keyphasor), and zero speed sensing applications.

Installation Guidelines

• System Length Matching: Ensure that the sum of the extension cable length (8.0 meters) and the probe length (1.0 meter) matches the calibrated length of the 9.0 meter Proximitor sensor.
• Bending Radius: Do not bend the armored cable below the recommended minimum bend radius of 30.5 mm (1.2 in) to avoid damaging the internal coaxial core.
• Connector Handling: Keep connectors dry and clean during installation. Only use approved, residue-free contact cleaners if cleaning is necessary.
• Connector Protection: Fully slide the pre-installed fluorosilicone connector protectors over the junction to seal it. Do not apply silicone tape if the connection will be exposed to turbine oils.
