Key Features and Advantages
The EPRO PR6423/000-101 is a high-precision, industrially proven eddy current displacement sensor designed for critical machinery condition monitoring. It is the industry standard for measuring radial vibration and axial position on rotating equipment such as turbines, compressors, and large pumps, providing vital data for protection and predictive maintenance.
Exceptional Reliability and Precision: Engineered for continuous operation in the most demanding environments, the PR6423 sensor delivers accurate and repeatable measurements of the dynamic gap between the probe tip and the rotating shaft. Its robust construction ensures long-term stability, which is fundamental for detecting early signs of machine distress like imbalance, misalignment, or bearing wear. The standardized 8.0 V/mm sensitivity ensures seamless compatibility with monitoring systems from EPRO and other major manufacturers. Robust Industrial Design: Built to withstand harsh conditions including high temperatures, pressure, oil, and steam, this sensor is a workhorse in power generation and heavy industry. The high-temperature rated cable and connector are integral to its reliability, ensuring signal integrity even when installed close to hot casings. The specific suffix “/000-101” denotes a particular configuration, possibly including a standardized cable length and connector type for easy replacement and inventory management. Easy Integration and Calibration: The sensor is pre-calibrated for a standard target material (AISI 4140 steel), providing accurate measurements “out of the box” and simplifying installation. Its compatibility with a wide range of proximitors and monitoring systems (such as EPRO’s MMS 6000 series) makes it a versatile choice for both new installations and legacy system upgrades, reducing engineering time and risk.

Product Application Scenario
On the high-pressure turbine of a combined-cycle power plant, two EPRO PR6423/000-101 sensors are installed 90 degrees apart in the same bearing housing to measure shaft vibration in the X and Y directions. A third sensor is used for axial position (thrust) monitoring. They continuously measure the minute changes in the gap to the shaft with micron-level precision. This data is transmitted to vibration transmitters (proximitors) and then to the plant’s machinery protection system (like an EPRO MMS 6420). A sudden increase in vibration amplitude detected by the PR6423 sensors could trigger an alarm, warning operators of a developing imbalance. Trending this data over time allows maintenance teams to predict bearing wear and schedule an outage before a catastrophic failure occurs, preventing millions in downtime and damage.

Product Functionality and Warranty
The EPRO PR6423/000-101 operates on the eddy current principle. An alternating current in the probe coil generates a magnetic field. When brought near a conductive shaft, eddy currents are induced in the shaft material, altering the coil’s impedance. This change is precisely proportional to the distance (gap) between the probe and the shaft. A connected proximitor converts this impedance change into a standardized DC voltage signal proportional to distance. We guarantee the supply of genuine, new EPRO sensors. Each unit is supplied with relevant documentation. Our products are backed by a 1-year warranty, and we provide technical support for integration and baseline measurement verification.
Application Areas
The EPRO PR6423 sensor is the global benchmark for protection and monitoring of high-speed rotating machinery. In Power Generation, it is used on steam turbines, gas turbines, hydro turbines, and generator sets for vibration and eccentricity monitoring. The Oil & Gas industry relies on it for centrifugal and reciprocating compressors, turbo-expanders, and pipeline pumps. Industrial Manufacturing applications include large motors, fans, blowers, and gearboxes in sectors like chemicals, metals, and cement. Any application where unplanned downtime of a critical machine carries a significant financial or safety risk is a prime application for this sensor.
