PR6423/013-030+CON021 EPRO Eddy Current Sensor 8mm Probe 3m Cable

Product Overview

The PR6423/013-030+CON021 is a full Emerson EPRO eddy current proximity transducer assembly for turbomachinery TSI (Turbine Supervisory Instrumentation) protection systems, widely used in power generation, oil & gas and petrochemical plants. This package consists of PR6423/013-030 8mm eddy current probe with factory-calibrated 3-meter extension cable paired with CON021 signal preamplifier. It uses non-contact eddy current principle to capture real-time shaft dynamic data without mechanical contact and wear on rotating rotors. Industrial procurement and maintenance engineers search directly by full part number PR6423/013-030+CON021 for spare replacement, unit overhaul and predictive maintenance projects.

Compatibility Notes

• The suffix -030on PR6423/013-030 stands for 3-meter extension cable. The probe, extension cable and CON021 preamplifier must remain as the original matched set. Changing cable length will cause sensitivity drift and inaccurate readings.
• PR6423/013-030 can only work with CON021 preamplifier; it cannot be interchanged with CON041 or other EPRO preamplifier models.
• The target surface shall be ferromagnetic steel (AISI 4140 / 42CrMo4) to maintain standard measurement performance.
• For TSI system integration, it can connect with EPRO VM600 monitoring racks, DCS and machinery protection controllers.

FAQ

Q: What is PR6423/013-030+CON021? A: PR6423/013-030+CON021 is Emerson EPRO full eddy current proximity sensor package. PR6423/013-030 is an 8mm probe with 3m extension cable, CON021 is the matched preamplifier for TSI shaft vibration and displacement monitoring.

Q: What does PR6423/013-030+CON021 measure? A: It measures shaft radial vibration, axial displacement, shaft position and eccentricity of high-speed rotating machines.

Q: Can I use PR6423/013-030 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 PR6423/013-030? A: Recommended initial air gap is 1.3 mm (50 mil), within the 2 mm linear measurement range.

Q: Is PR6423/013-030+CON021 interchangeable with PR6423/012-130+CON021? A: No. The suffix number represents cable length. PR6423/013-030 has a 3-meter cable while PR6423/012-130 is 13m. Cable length change will affect factory calibration and signal sensitivity.
