Description
Configured for shaft displacement, axial position, and relative vibration monitoring in rotating machinery, the Emerson Epro PR6423/059-110 (PR6423 Eddy Current Sensor) provides direct physical/electrical execution.
Suffix Breakdown & Model Matrix
The PR6423 sensor series utilizes structured ordering suffixes to define physical thread configuration, tip dimensions, and cable specs:
- PR6423: Core 8 mm tip diameter non-contact eddy current sensor base model for turbomachinery protection platforms.
- /059-110: Specific option variant designating case thread style, unarmored or stainless-steel flexible armored cable, overall integral cable length, and connector termination types.

4-20 mA HART Loop Protocol & Channel-to-Channel Isolation
The Emerson Epro PR6423/059-110 integrates into industrial transmitter and signal conditioning loops utilizing the standard 4-20 mA HART loop protocol. Physical shaft displacement detected by the 8 mm PEEK sensor tip modulates carrier frequency impedance, driving proportional 4-20 mA analog signals alongside HART digital telemetry for remote health diagnostics and parameter validation.
When connected to multi-channel transmitter racks, associated signal processing hardware features galvanic channel-to-channel isolation. This isolates individual measurement channels, preventing electrical ground loops and common-mode signal corruption across orthogonal x-y probe pairs mounted on turbomachinery bearing pedestals.
Frequently Asked Questions
Q: What target material is calibrated as standard for the PR6423/059-110?
A: The sensor scale factor (8.0 V/mm) is calibrated using standard 42CrMo4 (AISI/SAE 4140) ferromagnetic steel target material.
Q: What is the maximum temperature rating for the sensor cable and connector assembly?
A: The sensor head and first 1 m cable segment are rated up to +200 deg C, while the remaining cable assembly and nickel-plated brass connector are rated up to +150 deg C.
Field Installation Guidelines
- Thread the stainless steel probe body into the machine casing port until the initial air gap measures approximately 0.5 mm or the driver output reaches the nominal gap voltage (-10 VDC baseline).
- Ensure the shaft diameter at the target observation area is equal to or greater than 25 mm to prevent edge-effect signal distortion.
- Tighten mounting locknuts to the specified installation torque to eliminate physical drift caused by operating vibration.
- Insulate extension cable connections from machine casing ground and route cabling inside grounded conduit away from high-voltage supply leads.
