EPRO CON011 9200-00001N Signal Converter

The EPRO CON011 9200-00001N is a high-performance signal converter (also known as a proximity transducer or pre-amplifier) designed to interface with EPRO's PR642x series eddy current displacement sensors. It is a critical component in rotating machinery monitoring systems, converting the raw, modulated radio frequency signal from the sensor into standardized, industry-compatible analog outputs. This enables seamless integration with PLCs, DCS, and dedicated condition monitoring systems such as the EPRO MMS 6000. The CON011 is specifically engineered for non-contact measurement of key parameters including shaft vibration, axial displacement, eccentricity, and oil film thickness in turbomachinery like steam turbines, gas turbines, and compressors.

Applications

The CON011 is primarily used in rotating machinery protection and condition monitoring. It is ideal for measuring axial and radial shaft displacement, vibration, and eccentricity in turbines, compressors, and gearboxes. It is also employed in bearing oil film thickness analysis and as a key component in the MMS 6000 system for multi-parameter centralized monitoring and diagnostics. Its robust design makes it suitable for process control in the chemical and petrochemical industries for valve position and pressure vessel deformation monitoring.

Integration and Configuration

The module is designed for straightforward integration. It connects directly to EPRO PR642x sensors via integral or extension cables [citation:1]. The CON011 conditions the signal and provides outputs that can be wired directly to analog input modules of a PLC or DCS. For advanced applications, the RS485 interface with Modbus allows for digital communication of measured values, status, and diagnostic information. When used as part of an MMS 6000 system, it enables comprehensive machine monitoring and fault analysis.

Reliability and Environmental Compliance

Engineered for the demanding conditions of industrial environments, the CON011 offers an IP67 rating, ensuring reliable performance even in outdoor or wet locations. Its circuit design minimizes the impact of electrical noise and temperature fluctuations, providing stable and accurate measurements over time. The availability of ATEX-certified variants ensures safe operation in potentially explosive atmospheres, a critical requirement for many oil and gas applications.

The EPRO CON011 9200-00001N is an essential interface for bringing high-fidelity eddy current sensor data into modern industrial control and safety systems, ensuring the reliable protection of critical rotating assets.
