The PR6423/002-001 CON041 is a complete eddy current transducer system from Emerson‘s EPRO series, engineered for non‑contact displacement and vibration measurement on critical turbomachinery. The PR6423/002-001 8 mm probe features a 0.2 m integral cable, ideal for confined installations, and delivers 8 V/mm sensitivity with ±0.5% full‑scale accuracy and 1 μm resolution. The CON041 signal converter provides signal conditioning and standardized DC voltage outputs for integration with monitoring systems such as GE Speedtronic, Bently Nevada, and Emerson AMS. The PR6423/002-001 CON041 system is widely used in API 670‑compliant machinery protection systems for steam, gas, and hydro turbines, compressors, and pumps.
Sensor Mounting – Install the 8 mm probe using the M8x1 thread into a standard probe holder (e.g., EZ 1600). Ensure the probe is positioned perpendicular to the target surface with the recommended initial air gap of 0.5 mm (20 mils).
Cable Routing – The 0.2 m integral cable is designed for connection to an extension cable (e.g., PR6426 series) to reach the signal conditioner. Route cables away from high‑voltage lines and heat sources; minimum bending radius is 25 mm (0.984 in) for standard cable.
Converter Mounting – Mount the CON041 converter on a DIN rail using the integral clip.
Wiring – Connect the sensor extension cable to the converter‘s screw terminals. The converter requires a –23 V to –32 V DC supply.
Output Connection – The converter provides standardized DC voltage outputs (proportional to displacement) for connection to monitoring systems.
System Integration – The system is compatible with EPRO signal conditioners (e.g., CON021, MMS6312) and monitoring platforms such as GE Speedtronic, Bently Nevada, and Emerson AMS.
Shielding & Grounding – Use shielded twisted‑pair cable for the sensor connection. Ground the shield at the converter end only to avoid ground loops.
Hazardous Area Installation – For ATEX/IEC-Ex installations, observe the entity parameters and install per the relevant hazardous area drawings.
8 mm Eddy Current Probe – Non‑contact sensing eliminates mechanical wear, suitable for high‑speed rotating shafts
0.2 m Integral Cable – Short cable version ideal for confined spaces and tight installations
High Sensitivity (8 V/mm) – Delivers 1 μm resolution for precise displacement measurement
Wide Frequency Response (0–20 kHz) – Captures both static position and dynamic vibration signals
CON041 Signal Converter – DIN‑rail mounted module with <15 μs rise time for real‑time monitoring
Rugged Construction – Stainless steel housing and sealed PEEK tip resist oil, water, and contaminants
Wide Temperature Operation – Sensor tip operates from –30°C to +120°C
IP66/IP68 Protection – Probe body rated for dust‑tight and temporary immersion protection
Hazardous Area Approved – ATEX, IEC-Ex, and CSA certified for intrinsic safety (ia) and non‑sparking (nA) applications
API 670 Compliant – Suitable for machinery protection systems meeting API 670 standards
The PR6423/002-001 CON041 system operates on the eddy current principle. The probe 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 probe tip and the target surface.
The probe‘s short integral cable (0.2 m) connects to an extension cable, which routes the signal to the CON041 signal converter. The CON041 supplies the probe 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 provides an AC component proportional to dynamic vibration.
The system is factory‑calibrated to AISI 4140 (42CrMo4) ferromagnetic steel, with a sensitivity of 8 V/mm and a linear range of 2 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 operating temperature range. With ATEX/IEC-Ex intrinsic safety (ia) certification, the system can be installed in hazardous areas when connected through appropriate safety barriers.
Q1: What is the primary function of the PR6423/002-001 CON041 system?
A1: The PR6423/002-001 CON041 is a non‑contact eddy current transducer system that measures shaft vibration, axial position, eccentricity, and speed on critical rotating machinery such as turbines, compressors, and pumps.
Q2: What is the measurement range and resolution of this sensor?
A2: The PR6423/002-001 provides a linear measurement range of 2 mm (80 mils) with a resolution of 1 μm and an accuracy of ±0.5% of Full Scale.
Q3: What is the purpose of the short 0.2 m integral cable?
A3: The 0.2 m integral cable is designed for installations where space is limited or where the probe must be installed in a confined area, allowing the extension cable to be routed through conduit.
Q4: What is the CON041 signal converter and what does it do?
A4: The CON041 is a DIN‑rail mounted signal conditioner that converts raw eddy current probe signals into standardized DC voltage outputs (0–10 V or 4–20 mA) for integration with monitoring systems such as GE Speedtronic, Bently Nevada, and Emerson AMS.
Q5: Is the PR6423/002-001 CON041 still in production?
A5: No. The PR6423/002-001 CON041 was discontinued on December 31, 2018. However, brand‑new units remain available for legacy installations and replacement needs.
