Description

The Bently Nevada 102044-00-18-10-02, also cataloged as the 102044 Extension Cable, operates as a dedicated hardware component for transmitting high-frequency electrical signals between a proximity probe and a proximitor sensor within 3300 and 7200 5mm/8mm Eddy-Current Transducer Systems.

Hardware Specifications

Machinery Monitoring & TSI Characteristics

The Bently Nevada 102044-00-18-10-02 actively maintains system calibration across the entire eddy-current probe scaling sequence. Consequently, this component enforces a strict electrical length matching requirement to guarantee gap voltage validation (-10 VDC targets) during steady-state and dynamic shaft vibration monitoring. Furthermore, the integrated coaxial design incorporates high-density shielding. This configuration directly drives cross-talk suppression, preventing electromagnetic interference from distorting rotor dynamics calculations within the turbomachinery instrumentation system.

Frequently Asked Questions

Q: Does this extension cable support hot-swapping while the machinery protection system is online?

A: No. Disconnecting the extension cable alters the total system capacitance and impedance instantly. Therefore, this action triggers an immediate circuit fault or a false trip signal on the corresponding monitor module. Technicians must bypass or isolate the loop power before physical disconnection.

Q: How does the specific length option affect the calibration of the proximitor sensor?

A: Proximitor sensors require a specific total system length, typically 5.0 metres or 9.0 metres, to maintain accurate calibration. Because of this requirement, the 1.8-metre length of this cable must match the exact system configuration specified by the proximitor configuration. Otherwise, the system introduces calibration drift and measurement errors.

Field Installation Guidelines

• Minimum Bend Radius: Technicians must not exceed a minimum bend radius of 25.4 mm for unarmored versions and 31.8 mm for armored versions. Violating these limits damages the internal dielectric layer.
• Connector Torque and Isolation: Installers must finger-tighten the connectors until the click-loc mechanism engages. Following connection, users must insulate the coaxial junction using self-fusing silicone tape to prevent physical grounding against the machine housing or junction box.
• Terminal Grounding: Personnel must ground the cable shield at one single point only, typically at the proximitor sensor panel terminal. This installation practice effectively eliminates destructive ground loops.
