Bently Nevada 113819-01 High-Temp Vibration Probe Cable

Description

Product Introduction

The Bently Nevada 113819-01 is a specialized, ruggedized extension cable engineered to link proximity probes directly to downstream Proximitor sensor modules in critical machinery monitoring setups. Designed specifically for high-stress industrial environments, this cable assembly ensures reliable, noise-free transmission of dynamic gap and vibration signals from turbines, compressors, and large electric motors.

Unlike generic coaxial run-outs that degrade under high thermal exposure, the 113819-01 features a heavy-duty Teflon-coated fiberglass jacket and dual-layer shielding. This prevents ground loops, high-frequency electromagnetic interference, and thermal insulation breakdown near turbine casings or exhaust housings. Installing this genuine Bently Nevada extension cable preserves strict system calibration and signal integrity across the entire transducer loop.

Key Technical Specifications

Application Scenarios & The “Trench” Experience

Picture this: It is 2 AM on a Sunday, and your combined-cycle power plant trips on high shaft vibration. The DCS throws a channel fault alarm on bearing #2. You trek up to the turbine deck only to discover that an old, cheap extension cable jacket melted against a hot steam line. It compromised the shield and corrupted the 200 mV/mil RF signal. The whole plant is sitting idle at 15,000 an hour because of a 300 piece of wire. Having an OEM-grade, high-temp spare sitting on the shelf gets you back online before sunrise.

Key Industrial Scenarios

• Power Generation (Steam & Gas Turbines): Route signals from eddy current probes mounted in high-heat bearing housings out to junction boxes.
• Oil & Gas (Centrifugal Compressors): Continuous non-contact shaft displacement and phase-reference (Keyphasor) signal routing in hazardous areas.
• Petrochemical (Heavy Pumps & Blowers): High-vibration machinery trains where lower-grade cables suffer shield abrasion or connector fatigue.

Transparency SOP: Quality Assurance & Testing

We don’t just ship boxes; we test them on actual Bently Nevada test setups to ensure field readiness.

1. Inbound Inspection: Verify original OEM anti-counterfeit labels, part numbers, and connector physical integrity under magnification.
2. Continuity & Resistance Testing: Check center conductor and outer shield loop resistance against strict factory tolerances.
3. Dielectric Withstand / Megger Check: Perform high-voltage insulation testing between the inner core and shield to catch micro-cracks in the Teflon jacketing.
4. Live Signal Handshake: Hook the cable to a live Bently Nevada Proximitor, 3300 XL probe, and target material to verify linearity and mV/mil scale factor accuracy across a dynamic gap curve.
5. Final QC & Anti-Static Packaging: Clean connectors with isopropyl alcohol, fit protective dust caps on the BNC ends, and seal the unit in an ESD-shielded bag with moisture absorbers.

The Veteran’s Tech Trap Guide

• ⚠️ Capacitance Mismatch & Total Loop Length: Bently Nevada proximity probe systems (probe + extension cable + Proximitor) are tuned electrical systems meant for specific total lengths (usually 5-meter or 9-meter overall systems). Never randomly splice or chain two extension cables together. If you mix lengths, your scale factor drifts from the standard 200 mV/mil, rendering your vibration readings useless.
• ❗ Teflon Cold Flow & Tight Cable Ties: When securing this cable along conduit or tray wireways, do not cinching plastic zip-ties down with a tension gun. Excessive mechanical pressure deforms the Teflon dielectric over time, bringing the shield closer to the center core and changing loop capacitance. Use loose metal tie wraps or padded cable clamps instead.
• ⚠️ Connector Isolation at the Junction Box: The stainless steel BNC connector must remain electrically isolated from structural machine ground until it hits the Proximitor. Touch the metal connector body directly to a bare conduit box, and you will create a ground loop that masks true shaft vibration with 60 Hz electrical noise. Always use the factory silicone connector protector boots.
• ❗ Bend Radius Violations: Respect the minimum bend radius! Snapping a sharp 90-degree corner out of a tight junction box breaks the delicate foil/braid shield inside the fiberglass sheath. Keep your bends smooth and at least 2 inches in radius.

Frequently Asked Questions (FAQ)

Q: Is the 113819-01 hot-swappable at the Proximitor end?A: Yes, disconnecting the BNC end at the junction box or Proximitor will not damage the hardware. However, doing so instantly drops the channel signal to -24V DC, which will trip any connected machinery protection relays if the channel is unbypassed. Always drop the monitor rack channel into “Bypass” before pulling the cable.

Q: Can I use this extension cable with standard 3300 XL 5mm/8mm probes?A: Yes, as long as the total combined electrical length of the probe plus this cable matches the design rating of your Proximitor module (typically 5m or 9m total length). Check your system documentation to match system electrical lengths before swapping.

Q: Why choose New Surplus stock over ordering direct from the OEM?A: Lead times from factory distribution can take anywhere from 6 to 16 weeks depending on manufacturing runs. Buying New Surplus from our stock gives you an unblemished, factory-grade component delivered in days—saving thousands in potential forced outage downtime at a lower unit price.

Q: What is the warranty coverage on this surplus module?A: Every piece of surplus stock we ship comes with a full 12-month replacement warranty. If the cable fails electrical parameters or scale-factor bench tests within 365 days of installation, we swap it out immediately.

Q: Does this high-temperature version replace standard ambient extension cables?A: Absolutely. The high-temperature rated jacket (-20°C to +200°C) outperforms standard PVC-jacketed cables in every metric. You can safely deploy it in both standard ambient and extreme thermal zones without issue.
