Product Details
The Emerson PR6423/010-120-CN, also cataloged as the PR6423 Proximity Sensors, operates as a dedicated hardware component for non-contact shaft displacement and dynamic vibration measurement within Emerson and EPRO machinery monitoring platforms. The transducer assembly establishes an eddy current inductive field at the probe tip to convert physical gap variations relative to conductive metal targets into continuous electrical outputs without mechanical contact.

4-20 mA HART Loop Protocol & Channel Isolation
When wired into compatible CON series signal converters, the sensor interface delivers conditioned analog voltage or 4-20 mA HART loop protocol outputs to upstream monitoring racks. Galvanic channel-to-channel isolation decouples field sensor signals from system ground references, preventing common-mode earth potential interference in multi-channel installations. Internal thermal compensation preserves scale factor stability across wide operating temperature spans, ensuring accurate peak-to-peak vibration and axial position feedback.
Frequently Asked Questions
Q: What is the purpose of the CN suffix on the PR6423/010-120-CN sensor?
A: The CN suffix designates specific cable length, connector hardware, and terminal configurations tailored for standardized regional control panel installations.
Q: How does the eddy current transducer measure vibration without touching the shaft?
A: The probe coil emits a high-frequency electromagnetic field that induces eddy currents in the metal target, altering field impedance proportionally to physical gap distance.
Field Installation Guidelines
Maintain an unobstructed metallic clearance radius around the 8 mm sensing tip of at least 1.5 times the tip diameter to prevent surrounding enclosure geometry from inducing false inductance loading. Route sensor cabling inside dedicated grounded metallic conduit, maintaining physical separation from high-voltage AC cables and motor drives. Connect the cable shield braid to the technical earth terminal frame at a single point only to avoid circulating ground loop currents. Secure mounting locknuts to standard torque specifications and protect exposed connections with self-amalgamating tape.
