Product Introduction
The Epro PR6426/010-040 32mm Eddy Current Sensor is a high-precision non-contact displacement and vibration sensor specifically engineered for industrial machinery monitoring. It belongs to the PR6426 series, a line of eddy current sensors developed by Epro for the measurement of shaft position, vibration, and relative movement in rotating machines. This sensor operates based on the eddy current principle, producing an analog voltage proportional to the gap between the probe tip and the conductive target.
The PR6426/010-040 is built with a robust 32 mm sensing head, ensuring excellent stability, linearity, and signal quality even under demanding operational conditions. It is particularly suited for applications in turbines, compressors, generators, and other rotating equipment where early detection of mechanical anomalies is critical.
When paired with the Epro CON021 converter, the sensor delivers highly accurate, conditioned output signals for use in machinery protection and condition monitoring systems. Designed to withstand high temperatures, heavy vibration, and electromagnetic interference, this model represents a reliable, long-term monitoring solution for critical assets in power generation, petrochemical, and process industries.
