EMERSON PR6423/00R-010-CN Non-Contact Vibration Measurement Proximity Probe – PR6423 Series
When a critical rotating machine — a turbine, compressor, or pump — loses its shaft vibration monitoring capability, the consequences are immediate and severe. Without a reliable proximity probe in the measurement chain, operators are flying blind: abnormal shaft displacement goes undetected, protective shutdown systems lose their input signal, and catastrophic bearing failure or rotor rub can destroy millions of dollars of equipment in seconds. Unplanned downtime in process industries routinely costs $100,000 or more per hour. The EMERSON PR6423/00R-010-CN eddy current sensor is the precision instrument that stands between normal operation and disaster.
The PR6423/00R-010-CN occupies a well-defined technical position within EMERSON’s PR6423 proximity probe series — a product line that has become the de facto standard for shaft vibration and position measurement in turbomachinery protection systems worldwide. Engineered to interface directly with EMERSON’s 3300 XL and Bently Nevada monitor systems, this sensor delivers the non-contact, high-frequency dynamic response demanded by API 670-compliant machinery protection installations across oil & gas, power generation, and heavy process industries globally.

Frequently Asked Questions
Q: Is the PR6423/00R-010-CN compatible with the Bently Nevada 3500 system?
A: Yes. The PR6423 series probes are designed to interface with EMERSON Bently Nevada 3300 XL and 3500 series monitor systems when used with the appropriate proximitor/extension cable assembly.
Q: What does the “/00R-010-CN” suffix mean?
A: The suffix encodes the probe configuration: cable length, connector type (CN), and mechanical options. “/00R” indicates the standard radial probe configuration; “010” refers to the 1.0 m integral cable; “CN” specifies the connector style. Always order using the complete part number to ensure correct configuration.
Q: Can this sensor measure axial position as well as radial vibration?
A: The PR6423 series is primarily used for radial shaft vibration and relative shaft position measurement. Axial (thrust) position monitoring typically uses a dedicated thrust probe arrangement. Contact our team to discuss your specific measurement requirements.
Q: Do you provide a certificate of conformance or test report?
A: Yes. We can provide a certificate of conformance and, where available from the manufacturer, original test reports. Please request these documents at the time of inquiry.
Q: What is the typical lead time for the PR6423/00R-010-CN?
A: Lead time varies by current stock status. Please submit an inquiry for a real-time availability check. We typically respond within 24 business hours.
