The EA403 913-403-000-013 is an extension cable designed for TQ403 and TQ423 proximity measurement systems. The cable is used together with proximity transducers and IQS450 signal conditioners to extend the measurement chain in machinery protection and condition monitoring applications.
The EA403 extension cable adopts a 70 Ω coaxial structure with FEP insulation and shielded design for signal transmission in industrial environments involving rotating machinery, turbines, compressors, and vibration monitoring systems.
The FEP insulation material provides resistance against oil, moisture, chemicals,s and elevated temperatures commonly present in turbine cabinets, compressor skids, and industrial machinery monitoring environments.

Products Description
The EA403 extension cable forms a complete proximity measurement chain together with:
TQ403 proximity transducer
TQ423 proximity transducer
IQS450 signal conditioner
The system operates based on the eddy-current measurement principle for non-contact displacement monitoring of rotating shafts and moving machine components.
Typical monitored parameters include:
Shaft relative vibration
Axial displacement
Shaft position
Radial movement
Rotor expansion monitoring
The TQ403, EA403, and IQS450 form a proximity measurement system from Meggitt's vibro-meter® product line. This proximity measurement system allows contactless measurement of the relative displacement of moving machine elements.
Total System Length Configuration
The total system length (TSL) is calculated from:
--TQ4xx integral cable length
--EA403 extension cable length
Supported system configurations include:
--5 m Measurement Chain
1.0 m integral cable + 4.0 m extension cable
5.0 m integral cable without extension cable
--10 m Measurement Chain
1.0 m integral cable + 9.0 m extension cable
5.0 m integral cable + 5.0 m extension cable
10.0 m integral cable without extension cable
Connector and Installation Structure
The extension cable assembly uses self-locking miniature coaxial connectors with a female-to-male configuration. The connector structure supports vibration monitoring applications involving continuous machine operation and industrial installation environments.
Optional configurations may include:
--Flexible stainless steel hose protection
--FEP external sheath
--IP172 interconnection protector
--Ex-certified versions for hazardous areas
The minimum bending radius is:
--20 mm for cable section
--50 mm when a flexible stainless steel hose is installed
Operating Environment
The EA403 extension cable is designed for machinery monitoring systems operating in industrial environments involving:
Elevated temperatures
Oil exposure
Mechanical vibration
Electromagnetic interference
Hazardous industrial areas
Technical operating limits include:
Cable and connector temperature range: -40°C to +200°C
Vibration resistance: 5 g peak between 10 and 500 Hz
Shock resistance: 15 g peak

Notes: All dimensions are in mm unless otherwise stated.
1. The total system length = TQ403 integral cable length + EA403 extension cable length (E).
For information on combining integral and extension cables to obtain a particular total system length
For information on cable length tolerances, see Total system length trimming on page 4.
2. When optional protection,n such as a flexible stainless steel hose with or without an FEP sheath, is ordered: Flexible hose length (G) max. = EA403 extension cable length (E) − 150 mm, for an extension cable that is protected to the maximum extent possible ("cable fully covered").
