PR6424/011-140
Product Overview
The EPRO PR6424/011-140 is an eddy current displacement sensor from the Emerson EPRO PR6424 series. It is designed for non-contact measurement of shaft vibration, axial displacement and position in critical rotating machinery such as steam turbines, gas turbines, compressors, pumps and fans.
The PR6424 series is the 8 mm probe family within the EPRO sensor range, typically used for radial vibration and axial displacement monitoring where a larger measuring range than PR6423 is required. The “/011-140” suffix defines a specific configuration within the PR6424 family, typically related to cable length, connector type, mounting style or calibration details. Exact configuration should be confirmed against the product label before ordering.
Key Features
- Non-contact eddy current measurement with no mechanical wear
