The PR6424/000-041 CON041 is a 16mm eddy current displacement sensor paired with the CON041 signal converter, manufactured by Emerson ePRO (formerly Philips/Epro). This system measures radial shaft vibration and displacement in critical rotating machinery like steam and gas turbines.
CON041 Din Rail Mount Signal Converter
16mm Eddy Current Displacement Sensor
The probe head supports a maximum pressure of 10,000 hPa
In heavy industries like petrochemical processing and power generation, this hardware pair is deployed directly within the bearing pedestals and casings of steam turbines, turbo-compressors, hydro-turbines, and large industrial fans. It serves as the physical interface to map the mechanical boundaries of the rotor, delivering raw parameters for axial displacement, radial shaft vibration, eccentricity, and keyphase speed. The resulting high-frequency voltage data feeds directly into plant safety logic, allowing Distributed Control Systems (DCS), Programmable Logic Controllers (PLC), and Emergency Trip Systems (ETS) to execute safety shutdowns when mechanical thresholds are breached.

Thermal Power
Continuous monitoring of axial displacement and radial shaft vibration on megawatt-class steam turbines and generator rotors to prevent catastrophic stator-to-rotor rubs.
Petrochemical & Refining
Real-time position tracking of centrifugal compressors and high-pressure oil pumps to identify early-stage bearing wear and oil-film instabilities.
Hydroelectric Power
Shaft orbit mapping and runout measurement on large vertical hydro-turbine generator units under fluctuating hydraulic loads.
Oil & Gas
Keyphase tracking and speed logging on gas-turbine driven compressor stations to ensure continuous pipeline pressurization control.
Iron & Steel Metallurgy
Mechanical displacement tracking on blast furnace blowers and large oxygen compressor trains under high ambient vibration.
Nuclear Power
Non-contact shaft vibration monitoring on secondary-circuit main feedwater pumps and high-pressure cooling water pumps.
First, target materials must match properly because the voltage scale factor of 4 V/mm is factory-calibrated exclusively against 42CrMo4 steel, meaning that any alternative rotor material requires a complete recalculation of the output curves.
Second, the installation gap must be exact by locking the initial air gap near the 2.7 mm mechanical center to guarantee that the operational path remains within the 4.0 mm displacement span, preventing physical rotor-to-probe contact or signal saturation.
Third, cables are strictly unalterable since the factory cable length is precisely matched to the electrical loop impedance, meaning that cutting or splicing the cable is prohibited. Fourth, environmental safeguards must be adequate with the probe securely fastened to withstand the 10,000 hPa internal bearing pressure while the converter remains inside a junction box to maintain its IP20 rating.
Finally, noise immunity and grounding must be stringent by routing signal lines completely isolated from high-voltage power conduits and implementing a proper single-point shielded ground to block ambient electromagnetic interference.
The system operates on the principle of high-frequency electromagnetic induction. The forward coil of the PR6424/000-041 probe is activated by a high-frequency AC current supplied by the CON041 module, which generates a high-frequency magnetic field in the gap between the probe tip and the target metal surface (such as a rotating shaft). When the metal shaft undergoes axial movement, radial vibration, or rotational speed changes, its positional variation within the magnetic field causes fluctuations in the eddy currents on the metal surface. This fluctuation directly leads to an alteration in the impedance of the probe coil. The CON041 converter captures this impedance variation in real time and converts it into an analog voltage signal directly proportional to the gap distance. This signal can be routed directly into the plant DCS, PLC, or machinery condition monitoring and protection frameworks.
PR6424/000-041 CON041 is Eddy Current Displacement Sensor.
What is the primary working principle of PR6424/000-041 CON041?
It operates on the principle of the eddy current effect. The sensor tip emits an alternating electromagnetic field. When a metallic conductor approaches, eddy currents are generated on its surface, changing the amplitude of the high-frequency oscillator, which the converter translates into an electrical signal.
How to use products like PR6424/000-041 CON041?
Thread-mount the PR6424 sensor on the machine casing pointing at the shaft surface with a specific clearance gap; connect its integrated cable to the DIN-rail mounted CON041 converter; finally, wire the converter's output into a PLC or MMS condition monitoring system.
What are the core measurement functions of PR6424/000-041 CON041?
It is mainly used to measure radial and axial shaft displacement, shaft vibration, shaft eccentricity, keyphase, and rotating shaft speed.
Why does PR6424/000-041 CON041 have specific requirements for the target metal material?
Eddy current systems depend on the target metal's permeability and resistivity. The system is usually factory-calibrated for ferromagnetic steel (such as 42CrMo4 standard steel) and requires recalibration if the material changes.
