EA402 913-402-000-013-A2-E090-F0-G000

Product Overview

EA402 is an extension cable specially designed by Vibra-Meter for the TQ 422/TQ 432 series eddy current sensor systems. In eddy current measurement technology, the probe, extension cable and preamplifier together form a precise and tuned LC oscillation circuit. The electrical characteristics of the three must be precisely matched to ensure that the entire system achieves the nominal linearity, sensitivity and stability.

Model 913-402-000-013-A2-E090-F0-G000 is a 9.0-meter-long Intrinsically Safe extension cable. EA402 is specifically designed for condition monitoring systems that need to operate safely in high-risk explosive gas environments such as ATEX/IECEx Zone 0/1 or Class I Div 1. This cable adopts a special low-energy design concept and is marked with a prominent blue label, ensuring that even under internal or external fault conditions, the energy it releases is far lower than the minimum ignition energy required to ignite the surrounding explosive mixture, thereby providing the highest level of safety for personnel and equipment. The 9-meter length makes it suitable for complex industrial layouts where the distance between the probe and the preamplifier is relatively long.

Product functional features

Mechanical and chemical structures optimized for harsh industrial environments

The multiple advantages of FEP (fluorinated ethylene propylene) insulation layer

Wide temperature range stability: FEP can maintain excellent electrical and mechanical properties within the range of -200°C to +200°C, far exceeding common materials such as PVC or PE. This ensures that the performance of EA402 913-402-000-013-A2-E090-F0-G000 does not deteriorate near high-temperature steam pipes or in cold outdoor environments.

It has extremely strong resistance to the vast majority of industrial solvents, acids, alkalis, oils and fuels, and is very suitable for corrosive environments in petrochemical, chemical and other industries.

The low coefficient of friction and non-stickiness, along with a smooth surface, make it less prone to dust and oil stains, facilitating cleaning and reducing resistance during pipe threading.

Excellent flame retardancy, FEP material self-extinguishes when removed from the fire source, meeting industrial fire protection requirements.

The fine diameter of Ø3.6mm and the carefully designed conductor twisting method endow the 913-402-000-013-A2-E090-F0-G000 with excellent flexibility. The minimum bending radius of 20mm means that it can easily bypass complex structures on the machine and pass through narrow gaps, greatly simplifying the installation work near rotating equipment with limited space.

The trade-off between a 9-meter length and a shea-free design: The 9-meter length offers greater installation flexibility and is suitable for large units. The shea-free design sacrifices mechanical strength but brings ultimate flexibility and a smaller outer diameter. This makes EA402 an ideal choice for pipe laying. Under the protection of steel pipes or closed cable trays, its vulnerability is completely avoided.

The cornerstone of system integration and interoperability

The plug-and-play standardized interface, the EA402 adopts a micro push-in coaxial connector that matches the TQ probe and IQS preamplifier. This design ensures rapid, reliable and repeatable connections, avoiding performance inconsistencies and on-site construction risks caused by welding.

The length is modularized, offering multiple standard lengths. Users can flexibly combine them according to the actual distance, ensuring system performance while avoiding waste.

Seamless integration with the VM600 ecosystem, as an original factory accessory, its performance parameters have been fully incorporated into the database of the VM600 condition monitoring system. The configuration software will automatically apply the correct calibration parameters to achieve "out-of-the-box" functionality.
