Features

Low Signal Attenuation

Advanced conductor and insulation design minimizes signal loss (<0.5 dB/m at 1 MHz), ensuring accurate transmission of high-frequency sensor data (e.g., vibration waveforms) from probes to monitoring modules.

Extreme Temperature Resistance

FEP insulation and rugged jacket enable operation from -55°C to +200°C, making it suitable for high-heat applications such as turbine enclosures, exhaust systems, and industrial ovens.

Superior EMI/RFI Shielding

Dual-layer shielding with 90% coverage blocks electromagnetic and radio frequency interference, critical for reliable signal transmission in electrically noisy environments (e.g., near motors, transformers, or power lines).

Chemical and Abrasion Resistance

PVC jacket resists oils, solvents, and mechanical wear, ensuring longevity in harsh settings such as refineries, chemical plants, and mining operations.

Plug-and-Play Compatibility

Pre-terminated BNC connector and stripped/tinned leads simplify installation, ensuring secure connections with 3500 system modules and Bently Nevada proximity probes (e.g., 3300 XL series).

Function

The primary function of the 176449-02 is to transmit analog signals from sensors (e.g., proximity probes, vibration transducers) to the Bently Nevada 3500 monitoring system with minimal distortion or noise. It acts as a critical link in the measurement chain, preserving the integrity of raw sensor data—such as vibration amplitude, shaft position, or temperature—from the point of measurement to the system’s processing modules. By protecting signals from environmental interference and physical damage, it ensures the 3500 system receives accurate data for fault detection, analysis, and alarm generation.

Use

In industrial settings, the cable assembly is used to connect Bently Nevada proximity probes or vibration sensors to 3500 system modules (e.g., 3500/32M vibration monitors, 3500/60 temperature modules). It is routed from sensors mounted on machinery (e.g., turbine bearings, compressor shafts) to the 3500 system rack, with its flexible design allowing installation in tight spaces or around moving components. Its rugged construction withstands vibration, temperature cycles, and exposure to industrial fluids, ensuring continuous signal transmission in demanding operational conditions.

Application Fields

Power Generation

In coal, gas, and nuclear power plants, it connects proximity probes on turbine shafts and generator bearings to 3500 modules, ensuring accurate transmission of vibration and position data critical for preventing rotor instability or bearing failure.

Oil and Gas

Used in upstream drilling rigs, midstream pipelines, and downstream refineries to link sensors on centrifugal compressors, pumps, and gas turbines to monitoring systems, withstanding corrosive environments and high temperatures.

Chemical Processing

Connects vibration and temperature sensors on agitators, reactors, and heat exchangers to 3500 modules, resisting chemical exposure and maintaining signal integrity in humid or solvent-rich environments.

Pulp and Paper

Routes signals from paper machine roller sensors to monitoring systems, withstanding moisture, pulp residues, and mechanical stress from continuous machinery operation.

Mining and Metals

Links sensors on crushers, conveyor motors, and mill drives to 3500 modules, enduring dust, vibration, and extreme temperature fluctuations in rugged mining environments.

In summary, the Bently Nevada 176449-02 is a vital sensor cable assembly that ensures reliable signal transmission in the 3500 monitoring system. Its low attenuation, extreme environment resistance, and seamless compatibility make it essential for industries relying on accurate machinery health data to protect critical assets and optimize operations.
