EPRO PR6423/003-030-CN CON021 Eddy Current Vibration Sensor – PR6423 Series
When a critical rotating machine loses its vibration monitoring capability, the consequences are immediate and severe: undetected shaft imbalance, bearing wear, or rotor misalignment can escalate within minutes into catastrophic mechanical failure, unplanned downtime, and costly production losses. In high-stakes environments such as power generation turbines, compressor trains, and large pumping stations, the absence of a reliable vibration sensor is not merely an instrumentation gap — it is a direct threat to plant safety and operational continuity. The EPRO PR6423/003-030-CN CON021 eddy current vibration sensor is engineered precisely to eliminate that risk.
Within the EPRO PR6423 series — one of the most widely deployed eddy current sensor families in global turbomachinery protection — the PR6423/003-030-CN transducer paired with the CON021 signal conditioner represents a precision-matched system optimized for shaft radial vibration and position measurement. Trusted by OEMs and end-users across power, oil & gas, and petrochemical industries worldwide, this combination delivers the measurement accuracy and long-term stability demanded by API 670-compliant machinery protection systems.

Frequently Asked Questions
Q: Is the PR6423/003-030-CN CON021 a matched set or sold separately?
A: The PR6423/003-030-CN (probe + cable) and CON021 (signal conditioner) are sold as a matched, factory-calibrated system. Mixing with other conditioner models will affect calibration accuracy.
Q: Can this sensor replace a Bently Nevada 3300 XL 8mm probe?
A: In many installations, yes — the PR6423/003 shares the same 8mm tip diameter and similar sensitivity. However, always verify the conditioner output range and bias voltage compatibility with your monitoring system before substitution.
Q: What does “CN” mean in the part number?
A: “CN” designates the target material calibration — Conductive Non-magnetic, optimized for standard carbon steel or alloy steel shafts. For stainless steel or titanium shafts, a different calibration suffix is required.
Q: What is the lead time for this part?
A: Lead time depends on current stock. Please submit an inquiry for real-time availability. In-stock orders typically ship within 3–5 business days internationally.
Q: Do you provide a warranty?
A: Yes. We offer a 90-day warranty against manufacturing defects on all genuine parts. Warranty claims are handled directly by our technical support team.
