Sistem Sensor Arus Eddy Emerson PR6426/010-030 CON021/916-160

Description

The Emerson PR6426/010-030 non-contact sensor combined with the CON021/916-160 signal converter forms an advanced eddy current measurement system designed for critical turbomachinery applications, such as steam, gas, and hydro turbines, compressors, pumps, and fans. The PR6426 eddy current sensor specializes in measuring radial and axial shaft displacement, position, eccentricity, and motion under demanding industrial environments. The processed information is transferred via the CON021/916-160 converter to provide a stable electrical output for machine protection and TSI monitoring systems.

Features

• Non-contact eddy current measurement principle for precise tracking of industrial machine conditions 
• High-temperature durability with sensor head operation up to 175 degC 
• Built-in protection resisting pressures up to 6,500 hpa at the sensor head 
• Extended measurement range capacity up to 16.0mm optimized for large displacement detection 
• Rugged design with a standard stainless steel sleeve and high-end PTFE insulation 

Applications

• Radial and axial shaft displacement monitoring 
• Turbomachinery position, motion, and eccentricity verification 
• Critical machinery protection systems for gas/steam turbines and heavy compressors

Installation Guidelines

• Observe the minimum cable bending radius rules: 35 mm for armored configurations and 25 mm for non-armored cables.
• Keep a clear zone of at least 80 mm diameter around the sensor head free of unintended ferrous materials.
• Set the center air gap to approximately 5.5 mm nominal during initial probe gap adjustment.
• Ensure proper grounding and use external current limiting, such as safety barriers, when installing in certified hazardous areas.
