The Bently Nevada 102045-040-00-05 serves as the primary 102045 Extension Cable utilized to execute high-frequency analog signal transmission across 3300 XL platforms. The hardware establishes the electrical link between a proximity probe head and a remote Proximitor sensor, sustaining the RF impedance pathway required to measure static gaps and dynamic shaft displacements without signal degradation.

Configuration Options Breakdown

• 102045: Base catalog matrix code for the 3300 XL standard extension cable architecture.
• -040: Length matrix designation establishing a physical cable measurement of 4.0 meters (11.5 feet).
• -00: Standard configuration specifying unarmored coaxial cable layout with standard brass/copper connectors.
• -05: Multi-agency approval package certifying compliance under CSA, ATEX, and IECEx hazardous location standards.

Technical Performance Matrix

Eddy-Current Probe Scaling & Cross-Talk Suppression

The structural composition of the cable is built to match the exact capacitive and inductive profiles demanded by eddy-current probe scaling protocols. Maintaining a typical core capacitance of 69.9 pF/m enables continuous gap voltage validation (-10 VDC targets) without phase shifts or calibration loss in the field. This controlled impedance environment records raw high-frequency fluctuations caused by rotor dynamics while external multi-layered shielding prevents inductive interference. The outer shield layout ensures comprehensive cross-talk suppression inside common wire trays, preserving low-amplitude signal integrity alongside parallel high-temperature sensor configurations.

Physical Installation Manual

Conduit Layout Limits

• Enforce a strict minimum static bend radius of 25.4 mm (1.0 inch) during hardware routing through structural wire paths.
• Maintain a minimum separating clearance of 300 mm between this analog sensor cable and adjacent AC power circuits.

Connector Engagement Steps

• Align the coaxial pin connectors and thread them together finger-tight before completing the mechanical lock.
• Apply specialized silicone self-verifying tape or an approved boot assembly to protect the link from external fluid logging.

Electrical Termination Rules

• Do not slice, shorten, or alter the cable length since doing so destroys the 50 ohms calibration profile.
• Ground the outer shield layer exclusively at the Proximitor sensor housing termination blocks to prevent multi-point grounding paths.

Technical Support FAQ

• Q: Can this extension cable layout be hot-swapped while the Proximitor sensor loop is energized?

  A: Yes. It can be hot-swapped provided that the associated monitor channel alarms are temporarily bypassed to prevent false machinery shutdown actions.

• Q: Does this passive component increase the electrical load or backplane draw of the TSI system?

  A: No. The extension cable operates as a passive RF transmission medium, contributing zero electrical current draw or hardware load to the backplane.

• Q: What is the impact on eddy-current probe scaling if the total system length is mismatched?

  A: Mismatching a 4.0-meter cable with an uncalibrated probe length skews system tuning, causing a failure during gap voltage validation (-10 VDC targets).

• Q: Does the -05 agency approval option mandate the use of secondary barrier hardware in field circuits?

  A: Yes. To maintain the certified ATEX and CSA intrinsic safety parameters, the loop must route through approved galvanic isolation barriers.

• Q: What visual or electrical condition indicates that the internal copper core has degraded?

  A: An internal break increases the output resistance far above 50 ohms, driving the monitor output to an open-circuit fault level.

• Q: Are there any digital firmware flash compatibility steps required when swapping this item?

  A: No. The assembly is entirely analog and hardware-based, requiring no internal firmware, programming, or software calibration layers.

• Q: How does ambient temperature exposure up to +177 deg C affect structural capacitance limits?

  A: The internal fluoropolymer dielectric layer maintains stable electrical characteristics, keeping capacitance stable across the entire temperature scale.

• Q: Can the cable shield be grounded at both ends inside a wet industrial environment?

  A: No. Grounding both ends creates circulating multi-point loops that introduce electrical noise, disrupting high-frequency rotor dynamics tracking.
