Bently Nevada 20000-310 3300 Series Proximity Probe Extension Cable Product Brief Introduction

Length: 3 meters. Impedance: 50Ω ±1Ω. Construction: 7-conductor coaxial shielded. Operating temperature range: -50°C to +175°C. Voltage rating: 300V AC. Shield coverage: 100%. Connector type: 7-pin circular military-style connectors both ends.

Precision impedance matching ensures minimum signal reflection and accurate measurement. Full 360° shielding provides maximum immunity to electromagnetic interference. High-temperature fluoropolymer insulation suits turbine and engine environments. Rugged construction resists oil, chemicals and vibration. Keyed connectors prevent incorrect installation.

It extends proximity probe connections in shaft vibration monitoring systems, turbine displacement measurements, compressor condition monitoring, pump and motor shaft runout detection, and machinery protection systems.

Signal attenuation: <0.1dB per meter. Impedance tolerance: ±1Ω. Operating temperature range: -50°C to +175°C. Insulation resistance: >100MΩ @ 500V DC. Vibration resistance: 10G @ 10Hz to 2000Hz.

Center conductor: silver-plated copper. Dielectric: PTFE fluoropolymer. Shield: 100% tinned copper braid. Jacket: FEP fluoroplastic. Connectors: gold-plated copper alloy with nickel-plated steel shell.

It features 7-conductor coaxial construction, keyed 7-pin circular connectors at both ends, full-coverage braided shield, high-temperature fluoropolymer jacket, and molded strain relief boots.

It carries the high-frequency RF excitation signal from the proximitor to the proximity probe, and returns the amplitude-modulated displacement signal back to the proximitor for demodulation. The controlled impedance and full shielding preserve signal integrity and accuracy through the cable run.

Align connector keyways before mating. Tighten coupling nuts to specified torque. Maintain minimum bend radius of 10× cable diameter. Route cable away from high-temperature exhaust areas. Ground the shield at the proximitor end only.
