Vibration & Proximity Monitoring Solution – Emerson EPRO PR6423/015-000 | EPRO Series
Where This Product Is Used
The Emerson EPRO PR6423/015-000 is an 8mm eddy current proximity sensor engineered for continuous, non-contact measurement of shaft displacement, vibration, and position in rotating machinery. It is widely deployed in:
- Steam & Gas Turbines – radial shaft vibration and axial position monitoring per API 670
- Centrifugal Compressors – rotor dynamic analysis and surge detection
- Pumps & Fans – bearing housing vibration and shaft orbit measurement
- Gearboxes – gear mesh frequency and differential expansion tracking
- Hydro Turbines & Motor-Generator Sets – air-gap and eccentricity monitoring
- Petrochemical & Refinery Plants – continuous machinery protection systems
- Power Generation Facilities – OEM and retrofit machinery protection panels

Application-Specific FAQ
Q: Is the PR6423/015-000 compatible with Bently Nevada 3500 series monitors?
A: Yes. When paired with a CON021 or CON041 driver, the output signal is fully compatible with Bently Nevada 3500 series proximity inputs.
Q: What is the difference between PR6423/015-000 and PR6423/010-000?
A: The /015-000 variant features a 1.5m integral cable, while /010-000 has a 1.0m cable. Tip diameter and sensitivity are identical.
Q: Can this sensor measure non-ferrous targets?
A: The PR6423 series is calibrated for AISI 4140 steel. Non-ferrous targets (aluminum, titanium) will require recalibration of the driver output.
Q: What is the recommended gap setting for radial vibration measurement?
A: Typically 1.0 mm (center of linear range), corresponding to approximately −10 VDC output with a standard CON021 driver.
Q: Do you provide calibration certificates?
A: Calibration certificates from the original manufacturer are provided where available. Third-party calibration can be arranged upon request.
