PR6423/012-130+CON021 EPRO Eddy Current Sensor 8mm Probe 13m Cable

Product Overview

The PR6423/012-130+CON021 is a complete Emerson EPRO eddy current proximity transducer set, widely deployed in turbomachinery TSI (Turbine Supervisory Instrumentation) protection systems for power, oil & gas, petrochemical industries. This assembly combines the PR6423/012-130 8mm eddy current probe with factory-matched 13-meter extension cable and CON021 signal preamplifier. It adopts non-contact eddy current measuring principle to capture real-time shaft dynamic data without mechanical wear on rotating shafts. Industrial buyers, maintenance engineers and procurement teams search directly by full part number PR6423/012-130+CON021 for spare part replacement, overhaul and predictive maintenance projects.

FAQ

Q: What is PR6423/012-130+CON021? A: PR6423/012-130+CON021 is Emerson EPRO full eddy current sensor package. PR6423/012-130 is an 8mm probe with 13m extension cable, CON021 is the matched preamplifier for TSI shaft vibration and displacement monitoring.

Q: What does PR6423/012-130+CON021 measure? A: It measures shaft radial vibration, axial displacement, shaft position and eccentricity of high-speed rotating machines.

Q: Can I use PR6423/012-130 without CON021? A: No. The EPRO eddy current probe cannot operate independently. It must pair with the matched CON021 preamplifier. Cable length must match the model marking.

Q: What is the recommended installation gap for PR6423/012-130? A: Recommended initial air gap is 1.3 mm (50 mil), within the 2 mm linear measurement range.

Q: Is PR6423/012-130+CON021 interchangeable with PR6423/012-100+CON021? A: No. The suffix number represents cable length. PR6423/012-130 has a 13-meter cable while PR6423/012-100 is 10m. Cable length change will affect signal calibration.
