Field Application & Problem Solved
In rotating machinery monitoring—refinery turbines, power plant compressors, chemical plant pumps—the biggest cable-related challenge is proximity probes being too short for installation in tight or remote locations. Generic extension cables fail two critical tests: they lack EMI/RFI shielding (causing signal noise) and use incompatible connectors (leading to poor contact and signal loss). A Texas refinery lost $95k in a 2-hour outage when a generic cable’s unshielded conductors picked up VFD noise, triggering false vibration trips. A Pennsylvania power plant spent $18k annually replacing generic cables that failed due to oil degradation, as their PVC insulation couldn’t withstand turbine lube oil.
This extension cable solves these issues. You’ll find it in: turbine bearing housings, compressor baseplates, pump motor mounts, and any rotating asset where the probe is installed far from the proximitor. It’s the standard for retrofits or new installations where probe placement requires extra length without signal degradation.
Its core value is Bently-native compatibility + harsh-environment durability + signal integrity. Unlike generics, it’s impedance-matched to Bently probes/proximitors (50Ω), ensuring no loss of sensitivity or measurement accuracy. The PFA insulation resists oil, chemicals, and extreme temperatures, while the 100% braided shield blocks EMI/RFI. For a Louisiana chemical plant, this cable enabled installing a 330104 probe in a deep compressor housing, avoiding $25k in machinery modification costs to relocate the proximitor.
Installation & Maintenance Pitfalls (Expert Tips)
- Connector Torque: 0.8Nm (7.1 in-lbs): Rookies over-torque MIL connectors, stripping threads or damaging pins. A Florida refinery’s cable failed after 3 months when the connector was torqued to 1.5Nm—use a torque wrench with a MIL connector adapter to hit 0.8Nm.
- Shield Continuity: Verify Before Installation: Broken shields cause signal noise—use a multimeter to check continuity between shield lugs at both ends. An Ohio steel mill’s vibration data had 60Hz hum until a damaged shield was detected (no continuity). Replace the cable if shield continuity is broken.
- Avoid Daisy-Chaining Cables: Rookies chain multiple extensions to reach distant locations, increasing impedance and signal delay. A Michigan paper mill’s probe sensitivity dropped by 20% with two chained cables—use a single custom-length cable (Bently offers 10ft/20ft versions) instead of chaining.
- Cable Routing: 远离 Power Cables: Running the extension cable parallel to 480V+ power cables induces noise. A North Carolina water treatment plant’s pump probe gave erratic readings until the cable was rerouted 30cm away from motor power cables. Maintain minimum 15cm separation from AC power lines.
- Inspect for Physical Damage: Annually: Oil, chemicals, or mechanical abrasion degrade PFA insulation. A Texas refinery’s cable shorted after lube oil seeped through a small cut—inspect cables during shutdowns, focusing on bends and contact points with machinery.

Technical Deep Dive & Overview
The Bently 200350-00-00-00 is a purpose-built extension cable designed to maintain signal integrity between eddy current proximity probes and proximitors in harsh industrial environments. At its core, the cable’s 22 AWG stranded copper conductors and 50Ω impedance are matched to Bently’s probe/proximitor ecosystem, ensuring no loss of the 200-800 mV/mm sensitivity critical for accurate displacement/vibration measurements.
Unlike generic cables, the PFA insulation is chemically inert and heat-resistant, withstanding turbine lube oil, chemical vapors, and temperatures from -54°C to +121°C—far exceeding PVC-insulated generics. The 100% stainless steel braided shield provides EMI/RFI protection, blocking interference from VFDs, motors, and power cables that would corrupt the probe’s low-voltage signal. The MIL-C-5015 connectors are industrial-grade, with a secure thread-lock design that prevents vibration-induced loosening.
What sets it apart is its seamless integration with Bently’s monitoring systems. It requires no signal boosters or adapters, as it’s engineered to the same specifications as the probe’s integral cable. The cable’s dynamic bend radius (25mm) accommodates machinery vibration without damaging conductors or insulation. For maintenance teams, this cable isn’t just an extension—it’s a reliable link that ensures critical proximity probe data reaches the monitoring system intact, enabling early fault detection and preventing unplanned downtime.
