Bently Nevada 330190-040-00-05 Extension Cable

The Bently Nevada 330190-040-00-05, also cataloged as the 330190 Extension Cable, operates as a dedicated hardware component for signal transmission and impedance-controlled interconnection within 3300 XL Extended Temperature Range (ETR) proximity transducer systems. The cable provides calibrated electrical continuity between the proximity probe and Proximitor sensor while maintaining displacement measurement accuracy under elevated temperature conditions.

Hardware Specifications

Eddy-Current Probe Scaling and Gap Voltage Validation

The 330190 extension cable is a calibrated element of the 3300 XL Extended Temperature Range transducer system. Electrical characteristics such as impedance, capacitance, and conductor resistance are controlled to maintain displacement measurement accuracy across the complete probe-extension cable-Proximitor assembly.

Proper system performance depends on matching the extension cable with approved 3300 XL ETR probes and Proximitor sensors configured for the correct system length. During commissioning, gap voltage validation is commonly performed to confirm the transducer system operates within its calibrated measurement region, typically centered near the standard -10 VDC target used in Bently Nevada eddy-current monitoring systems.

The PFA-insulated triaxial construction supports operation in locations where elevated temperatures exceed the limits of conventional proximity transducer cabling.

Frequently Asked Questions

Q: Can the 330190-040-00-05 be used with standard 3300 XL components?
A: The extension cable is designed for 3300 XL Extended Temperature Range transducer systems and should be matched with compatible ETR system components to maintain calibration integrity.

Q: Does the cable require external power?
A: No. The cable is a passive assembly and functions as part of the complete proximity transducer system.

Q: Is the cable suitable for high-temperature machinery installations?
A: Yes. The cable is rated for continuous operation from -52 deg C to +260 deg C and utilizes PFA insulation for elevated-temperature applications.

Field Installation Guidelines

• Verify compatibility between the ETR probe, extension cable, and Proximitor sensor before installation.

• Do not shorten, splice, or modify the factory-calibrated cable assembly.

• Maintain the minimum cable bend radius of 25.4 mm during routing.

• Route transducer cables separately from high-voltage and high-current conductors.

• Protect connectors from contamination during installation and maintenance.

• Avoid exceeding the specified 270 N tensile load limit.

• Confirm shield continuity throughout the complete transducer system.

• Verify acceptable gap voltage values before placing machinery into service.
