Emerson PR6426/010-000 CON021/916-160 Wirbelstrom-Sensorsystem

Description

The Emerson PR6426/010-000 non-contact sensor combined with the CON021/916-160 signal converter forms an industrial eddy current measurement system optimized for critical turbomachinery applications, including steam, gas, and hydro turbines, compressors, pumps, and fans. The PR6426 eddy current sensor detects radial and axial shaft displacement, position, eccentricity, and motion under harsh operating conditions. The matched CON021/916-160 converter accurately processes these proximity metrics into reliable electrical signals required by machinery protection and TSI monitoring platforms.

Features

• Non-contact eddy current measurement technique for precise tracking of shaft position and dynamics
• Robust engineering built to withstand demanding and tough industrial conditions
• Sensor tip assembly capable of enduring high pressure up to 6,500 hpa
• Stable signal translation over an extended displacement range up to 16.0mm
• Unarmored cable layout equipped with a premium self-locking plug connector interface

Applications

• Radial and axial shaft dynamic displacement monitoring
• Turbomachinery position, motion, and eccentricity registration
• Comprehensive mechanical protection loops for high-speed gas/steam turbines and heavy compressors

Installation Guidelines

• Ensure the unarmored sensor cable respects a minimum static bending radius of 25 mm during routing.
• Keep a clear exclusion zone of at least 80 mm diameter centered around the 32mm sensor head to eliminate peripheral metal interference.
• Adjust the mechanical probe position to find the nominal center air gap of approximately 5.5 mm before locking down.
• Use appropriate safety barriers and signal isolation paths when routing transducer loops through explosive or certified hazardous zones.
