Description

Brief Product Description

The Vibro-Meter EA402 (913-402-000-013) is a high-performance extension cable designed to bridge TQ-series proximity probes and IQS-series signal conditioners. This ruggedized component enables precise non-contact vibration and displacement monitoring for critical rotating machinery in extreme thermal environments.

Specialized Signal Transmission for Machinery Protection

The Vibro-Meter EA402 extension cable serves as the critical link within a comprehensive proximity measurement chain. By connecting TQ402 or TQ412 sensors to IQS900 conditioners, this system facilitates the real-time monitoring of shaft relative vibration and axial position. These measurements prove essential for the safe operation of high-speed turbines, industrial compressors, and large-scale pumps. The EA402 ensures that low-level displacement signals travel from the sensor to the processing electronics without interference or loss of accuracy. Consequently, industrial operators can rely on this hardware to meet the stringent machinery protection standards outlined in API 670.

Exceptional Thermal Stability and Environmental Resistance

Engineers specifically developed the EA402 to withstand the punishing conditions found in power plants and petrochemical facilities. The cable maintains operational integrity across a vast temperature range from -40°C to +180°C, accommodating both cryogenic and high-heat applications. Furthermore, the stainless steel hardware and specialized jacketing provide robust resistance against corrosive chemicals and mechanical wear. This durability ensures that the proximity system delivers a consistent frequency response from DC up to 20kHz. By utilizing this temperature-compensated extension, the system eliminates measurement drift, providing maintenance teams with reliable data for predictive analytics and emergency shutdown triggers.

Versatile Configuration and Industrial Compliance

The EA402 913-402-000-013 supports various industrial mounting requirements through its flexible design and MIL-C-5015 connector compatibility. This specific model integrates seamlessly into 5-meter and 10-meter measurement chains, allowing for customized sensor placement based on machinery geometry. Additionally, many versions carry EX certifications, permitting safe deployment within hazardous areas where explosive atmospheres may exist. Transitioning to a Vibro-Meter measurement solution enhances overall system reliability, as the EA402 is engineered to minimize signal noise while providing the high-fidelity feedback required for advanced PLC and DCS vibration monitoring platforms.
