Product Details
The Emerson PR6424/003-030 CON021, also cataloged as the PR6424 / CON021 Eddy Current Sensor, operates as a dedicated hardware component for non-contact shaft displacement and vibration measurement within turbomachinery protection platforms. The sensing system generates a high-frequency electromagnetic field at the probe tip to detect microscopic gaps between the sensor face and target conductive metal surfaces. The associated converter conditions this physical proximity response into a proportional continuous analog output signal for direct processing by machinery monitoring systems.

4-20 mA HART Loop Protocol & Signal Conditioning
The integrated converter circuit employs a 4-20 mA HART loop protocol to transmit primary dynamic displacement variables alongside internal diagnostic field data over standard two-wire connections. Galvanic channel-to-channel isolation prevents ground loop currents from distorting high-frequency displacement signals during multi-channel bearing rack operations. Analog output scaling maintains predictable linearity across the target measuring range, minimizing total loop noise and thermal drift over prolonged continuous operation.
Frequently Asked Questions
Q: What power supply arrangement is required to power the signal converter?
A: The converter requires an external 24 VDC power supply connected via shielded twisted-pair cabling. Loop power must remain within specified operating voltage thresholds to ensure stable oscillator output.
Q: How does loop shield termination affect signal integrity?
A: Signal cable shielding must be connected to functional earth at a single point, typically at the monitoring cabinet terminal frame, to avoid dual-ground potential differences and loop noise.
Field Installation Guidelines
Mount the probe tip securely using designated bracketry, ensuring a minimum side-wall clearance of 1.5 times the tip diameter to eliminate extraneous metal interference. Route sensor cables through dedicated grounded metal conduits separated from high-voltage motor supply wiring. Tighten all cable connectors finger-tight plus one-quarter turn to maintain environmental sealing, and apply self-amalgamating tape over external outdoor joints. Maintain a minimum bend radius of 30 mm along extension cables during field installation.
