Bently Nevada 330190-040-00-00 3300 XL Extended Temperature Range (ETR) Extension Cable

Description

Serving as a high-integrity link within critical machinery protection systems, the Bently Nevada 330190-040-00-00 provides precise signal transmission between proximity probes and sensor transition electronics. This 3300 XL series Extended Temperature Range (ETR) extension cable is engineered to maintain signal integrity and precise coaxial impedance under severe industrial thermal cycling. Capable of enduring harsh environments without degradation, it ensures continuous vibration, position, and speed feedback for heavy rotating machinery.

Features

• Extended Temperature Capability: Engineered with advanced materials to withstand temperature extremes across industrial plant environments.
• Calibrated Length: Exactly 4.0 meters in length to match transducer system electrical calibration metrics.
• Excellent Shielding: High-density braided shield prevents electrostatic and electromagnetic interference in noisy environments.
• Rugged Coaxial Design: Built to maintain precise capacitance and resistance properties under constant machine vibration.

Applications

• Steam and gas turbine shaft vibration and axial thrust position monitoring.
• High-pressure hydrocarbon compressor and expander diagnostics.
• Power generation generator stator and bearing housing monitoring.
• Critical water pumps, draft fans, and cooling towers in power and processing plants.

Alternative Models & Compatibility

This cable is fully backwards-compatible with standard Bently Nevada 3300 XL 8mm proximity probe systems. Mixing ETR components with standard-temperature system components is fully supported electronically, though the overall system's maximum temperature threshold will be restricted to the lowest-rated element.

Application Pitfalls & Engineering Notes

While ETR cables are built for wide thermal boundaries, ensure the minimum bend radius of 25.4 mm (1.0 inch) is strictly maintained. Violating this radius can cause local physical deformations in the inner coaxial conductor, altering the cable impedance and introducing measurement signal drift or calibration errors.

Commissioning & Wiring Tips

When routing the cable through conduit or open trays, always protect the miniature coaxial connectors. Use plastic pull-caps or connector protectors to prevent dirt, water, or oil from penetrating the dielectric layer before final termination is complete.
