Product Introduction
The Epro PR6426/010-130 is a high-precision eddy current displacement sensor designed for non-contact vibration and axial position measurements in rotating machinery. With a sensing diameter of 32 mm, this probe is part of Epro’s well-established PR6426 series and is tailored for large shaft or surface monitoring applications where accurate, reliable, and rugged sensing is essential.
When paired with the Epro CON041 or CON021 converter and the Epro MMS6000 monitoring system, the PR6426/010-130 forms a vital part of a complete condition monitoring and machinery protection solution. It is particularly well-suited for use in steam turbines, gas turbines, compressors, gearboxes, and large motors.
