Product Description

Overview

The Bently Nevada 175794-01 is a high-precision Simplex Terminal Base within the ADAPT 3701/44 series, designed for monitoring complex rotating machinery, including aero-derivative gas turbines, compressors, gearboxes, and rolling element bearing systems. Serving as the interface between field sensors and the ADAPT system’s signal processing modules, this terminal base enables distributed installation close to machinery, reducing cabling complexity while maintaining high signal integrity.

This module provides a reliable connection point for vibration, speed, and temperature sensors, ensuring the accurate transfer of high-resolution data for condition monitoring and protective automation.

Technical Specifications

Performance and Features

Advanced Signal Processing: Optimized for aero-derivative turbines with order tracking, narrowband filtering, and combustion monitoring to capture mechanical or acoustic anomalies.

High-Resolution Data Acquisition: 24-bit ADC captures fine vibration and thermal signatures, supporting a variety of sensor types, including vibration, velocity, temperature, and Keyphasor speed inputs.

Distributed Protection: Placing the 175794-01 near the machine reduces wiring length, lowers EMI risk, and allows local alarm handling with programmable relay outputs.

System Integration: Compatible with Bently Nevada System 1 software and Distributed Control Systems, with dual Ethernet for redundancy.

Applications

• Aero-derivative and industrial gas turbines

• Compressors and high-speed rotating equipment

• Gearboxes and bearing condition monitoring

• Skid-mounted machinery requiring distributed monitoring
