PR6423/014-040 EPRO Eddy Current Probe 8mm with 4m Extension Cable

Product Overview

The PR6423/014-040 is an Emerson EPRO eddy current proximity probe assembly, designed for TSI (Turbine Supervisory Instrumentation) protection systems in power, oil & gas, petrochemical and chemical industries. This unit consists of an 8mm eddy current probe pre-fitted with factory-calibrated 4-meter extension cable. It must work with a matched CON021 preamplifier to form a complete transducer system for non-contact rotor dynamic measurement. Maintenance engineers and procurement teams search directly by full part number PR6423/014-040 for equipment overhaul, spare replacement and predictive maintenance projects.

Key Features

• Non-contact eddy current measurement: No physical contact with rotating shaft, no wear and long service life
• Factory matched cable: 4m extension cable calibrated together with the probe, pairing with CON021 preamplifier
• Standard sensitivity: 8 V/mm ±5% within 0~45℃ ambient temperature
• Linear measuring range: 2 mm (0–80 mil), recommended installation air gap: 1.3 mm (50 mil)
• Wide probe temperature range: -35℃ ~ +180℃, suitable for high-temperature turbine casing environments
• LEMO connector at cable end for reliable connection to CON021 preamplifier
• API 670 compliant for critical turbomachinery protection applications

Applications & Industries

PR6423/014-040 eddy current probe is used to measure shaft radial vibration, axial displacement, shaft position and eccentricity. Typical rotating equipment:

• Steam turbines, gas turbines, hydro turbines
• Centrifugal compressors, axial compressors
• Large industrial pumps, fans and gearboxes
• Rotating machinery TSI monitoring and machinery protection systems

Industry sectors: Power generation, oil & gas, petrochemical, chemical processing, pulp & paper.

Compatibility Notes

• Suffix -040means 4-meter extension cable. The probe and cable are calibrated as one assembly. Changing cable length will cause sensitivity drift and inaccurate readings.
• PR6423/014-040 requires CON021 preamplifier for operation. It cannot be used alone or interchanged with CON041 / CON031 without re-calibration.
• Target surface material should be ferromagnetic steel (AISI 4140 / 42CrMo4) to guarantee standard measurement performance.
• It can integrate with EPRO VM600 rack systems, DCS and other machinery protection controllers.

FAQ

Q: What is PR6423/014-040? A: PR6423/014-040 is an 8mm EPRO eddy current probe with 4m extension cable. It needs to pair with CON021 preamplifier to build a complete TSI sensor system for shaft vibration and displacement monitoring.

Q: What does PR6423/014-040 measure? A: It measures shaft radial vibration, axial displacement, shaft position and eccentricity of high-speed rotating machinery.

Q: Can PR6423/014-040 work without CON021? A: No. The eddy current probe cannot work independently. A matched CON021 preamplifier is mandatory. Cable length must match the model marking.

Q: What is the recommended installation gap for PR6423/014-040? A: Recommended initial air gap is 1.3 mm (50 mil), within the 2 mm linear measurement range.

Q: Can I replace PR6423/014-040 with PR6423/013-030? A: Not directly. PR6423/014-040 has a 4m cable while PR6423/013-030 is 3m. Different cable lengths have different factory calibration parameters.
