مقدمة المنتج
The Epro PR6423/000-030-CN+CON021 8 mm Eddy Current Sensor is a high-precision proximity probe designed for continuous, non-contact measurement من shaft vibration, radial displacement, and rotor position in rotating machinery. Built to withstand harsh industrial conditions, this sensor uses the eddy-current principle to detect changes in the distance between the probe tip and a conductive target. The result is a reliable output signal proportional to displacement, enabling predictive maintenance and protection من turbines, compressors, pumps, and other critical equipment. Its rugged construction and high sensitivity make it suitable for long-term use in power generation, petrochemical, and heavy-duty process industries.

FAQ
-
What principle does the PR6423 sensor use for displacement measurement?
It operates on the eddy current principle, inducing currents in the conductive target and measuring impedance changes to determine distance. -
Can the sensor be used in high-temperature environments?
Yes, the probe operates up to +180 °C and the CON021 converter up to +85 °C. -
What is the typical linear measurement range?
The standard linear range is 0 – 2 mm with factory calibration. -
How is the sensor powered?
It is powered through the CON021 converter with a ±15 V DC supply. -
Does the sensor require regular calibration?
Calibration is recommended during installation and major maintenance, but frequent recalibration is not needed thanks to stable factory settings. -
What type من output signals are supported?
The system provides a voltage or 4–20 mA current output proportional to displacement. -
Is the probe tip resistant to oil or chemical exposure?
Yes, the stainless steel and ceramic construction provides strong resistance to oil, lubricants, and most industrial chemicals. -
Can the PR6423 be used for both vibration and shaft position monitoring?
Absolutely; it can monitor both dynamic vibration and static radial displacement. -
What is the recommended installation clearance from the target?
Typically around 1 mm nominal gap to ensure the full measurement range and linearity. -
Is the sensor suitable for hazardous areas?
Yes, when paired with appropriate intrinsically safe barriers or certified CON021 modules, it meets ATEX/IECEx requirements.
