Description

The PR6424/012-010 CON011 is a complete eddy current transducer system from Emerson‘s EPRO series, engineered for non‑contact displacement and vibration measurement on critical turbomachinery. The PR6424/012-010 16 mm sensor delivers a 4 V/mm sensitivity with ≤±1.5% linearity, while the CON011 signal converter provides signal conditioning and standardized outputs for integration with monitoring systems. The PR6424/012-010 CON011 system offers a ±2.0 mm static range and 0–1,000 μm dynamic range, making it ideal for radial and axial shaft monitoring on turbines, compressors, and generators. With IP66 protection and ATEX/IEC-Ex certification, the system is suitable for demanding industrial and hazardous environments.

Installation & Wiring

Sensor Mounting – Install the 16 mm probe using the M18x1.5 or 3/4″-16 UNF thread into a stiff, vibration-free holder.
Distance Adjustment – Adjust the gap between sensor tip and target surface. Use a voltmeter connected to the converter output to measure output voltage during adjustment.
Cable Routing – Do not bend or twist the sensor cable. If the cable has a LEMO adapter plug, open it during installation and close it for measurement.
Cable Length – The CON011 converter supports cable lengths up to 300 m with its >100 kΩ input resistance.
Converter Mounting – Mount the CON011 converter on a DIN rail. Connect the sensor to the converter via extension cable (PR6426 series).
Power Connection – Connect a –23 V to –32 V DC power supply to the converter.
Output Connection – The converter provides –4 V to –20 V proportional signals for connection to monitoring systems.
Shielding & Grounding – Use shielded twisted‑pair cable; ground the shield at the converter end only to avoid ground loops.
Hazardous Area Installation – For ATEX/IEC-Ex installations, observe entity parameters and install per relevant hazardous area drawings.

Theory of Operation

The PR6424/012-010 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 of ±2.0 mm) and provides an AC component proportional to dynamic vibration (0–1,000 μm).

The system is factory‑calibrated to AISI 4140 (42CrMo4) ferromagnetic steel, with a sensitivity of 4 V/mm and linearity of ≤±1.5%. The CON011 converter offers a frequency range of 0–20,000 Hz (–3 dB bandwidth) and a rise time of <15 μs, ensuring rapid response to transient events. The sensor‘s stainless steel housing and PTFE‑insulated cable maintain 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.
