Rotating Machinery Vibration Monitoring Solution – Emerson PR6423/015-030 | EPRO Series
Where This Product Is Used
The Emerson PR6423/015-030 eddy current sensor is engineered for continuous, non-contact displacement and vibration measurement in high-speed rotating machinery. Typical deployment environments include:
- Steam & Gas Turbines – shaft radial vibration and eccentricity monitoring per API 670
- Centrifugal Compressors – rotor dynamic displacement in petrochemical and LNG plants
- Pumps & Fans – bearing journal orbit analysis in power generation facilities
- Gearboxes – gear mesh frequency and shaft position tracking
- Marine Propulsion Systems – shaft alignment verification under load
Engineers in oil & gas, power generation, pulp & paper, and heavy manufacturing rely on the PR6423 series for its proven signal linearity and robust construction in harsh industrial environments.

Application-Specific FAQ
Q: Is the PR6423/015-030 compatible with the Emerson 3500 rack system?
A: Yes. When paired with the correct extension cable and CON021 or PR6426 driver, it integrates directly with the Emerson 3500 Series machinery protection rack.
Q: Can this sensor be used on non-ferrous targets such as aluminum or titanium?
A: Eddy current sensors are sensitive to target material conductivity and permeability. A calibration correction factor is required for non-standard target materials. Contact us for application guidance.
Q: What is the difference between PR6423/015-030 and PR6423/010-030?
A: The /015 designates a 15 mm probe tip diameter versus 10 mm for the /010 variant. The larger tip provides a wider linear measurement range and is preferred for larger shaft diameters.
Q: Do you supply ATEX-certified versions?
A: Emerson offers ATEX/IECEx variants of the PR6423 series. Please specify your hazardous area classification when requesting a quote.
Q: Can Konmask provide calibration certificates?
A: Calibration certificates from accredited labs can be arranged upon request. Please indicate this requirement at time of order.
