Description

The PR6424/012-000 CON011 is a complete eddy current transducer system from Emerson‘s EPRO series, purpose-built for non‑contact displacement and vibration measurement on critical turbomachinery. The PR6424/012-000 16 mm sensor delivers a 4 V/mm sensitivity with ±1.5% linearity, while the CON011 signal converter provides signal conditioning and output for integration with monitoring systems. The PR6424/012-000 CON011 system offers a ±2.0 mm linear range, IP66 protection, and ATEX/IEC-Ex certification, making it ideal for radial and axial shaft monitoring on turbines, compressors, and generators.

Competitive Advantage

True Non-Contact Measurement – Eliminates mechanical wear and friction, ensuring long‑term reliability with zero maintenance on the sensing element itself.
High Temperature Capability – Sensor withstands up to 200°C at the tip and 150°C at the cable/connector, making it suitable for high‑temperature turbine casings and compressor stages where many competitive sensors would fail.
API 670 Compliance – Meets international standards for turbomachinery monitoring, ensuring compatibility with industry best practices and regulatory requirements.
Hazardous Area Certified – ATEX, IEC-Ex, and CSA approvals (intrinsic safety and non‑sparking) simplify global deployment in Zone 0/1/2 and Division 1/2 hazardous locations.
Small Target Compatibility – Measures accurately on shafts as small as 80 mm diameter, enabling use on smaller turbines, gearboxes, and pumps.
True Interchangeability – Factory‑calibrated to AISI 4140 steel with precise ISF and DSL specifications, allowing sensor replacement without field recalibration—reducing downtime and maintenance cost.
Integrated Signal Converter – The CON011 converter provides direct connection to monitoring systems with built‑in short‑circuit, open‑circuit, and reverse‑polarity protection.

Theory of Operation

The PR6424/012-000 CON011 system operates on the eddy current principle. The sensor contains a coil that generates a high‑frequency electromagnetic field. When a conductive target (such as a rotating shaft) enters this field, eddy currents are induced in the target surface, which in turn alter the impedance of the sensor coil. This impedance change is directly proportional to the distance between the sensor tip and the target surface.

The CON011 signal converter supplies the sensor with a high‑frequency excitation signal and continuously monitors the resulting impedance changes. It converts these changes into a calibrated DC voltage output proportional to the probe‑to‑target gap (static displacement) and an AC voltage output proportional to dynamic vibration. The converter provides outputs protected against short circuits, open circuits, and reverse polarity.

The system is factory‑calibrated to AISI 4140 (42CrMo4) ferromagnetic steel, with a sensitivity of 4 V/mm and a linear range of ±2.0 mm. The sensor’s PEEK tip and stainless steel housing ensure durability in harsh environments, while the PTFE‑insulated cable maintains signal integrity across the full –35°C to +150°C operating range. With ATEX/IEC-Ex intrinsic safety (ia) certification, the system can be installed in hazardous areas when connected through appropriate safety barriers.
