Configured for non-contact displacement and shaft vibration measurement in AMS Machinery Health Monitor systems, the Emerson PR6426/010-010 (PR6426/010 Eddy Current Displacement Sensor) provides direct physical/electrical execution.

Part Number Nomenclature & Options

• Base Model (PR6426/010): Non-contact eddy current transducer featuring a 12 mm tip diameter and M14x1.5 threaded body.
• Cable Configuration (-010): Integrated stainless steel armored cable with a total length of 1.0 m terminated by a open/connector interface.

Technical Performance & Physical Properties

Fieldbus Connectivity & Process Signal Integration

When paired with CON transmitter units, the sensor outputs physical displacement metrics scaled for analog process control integration. The converted signal interfaces seamlessly with 4-20 mA HART loop protocol infrastructure or DCS I/O cards. Internal channel-to-channel isolation within processing racks prevents ground loop corruption, while high-frequency excitation ensures noise-immune transmission over field wiring backplanes.

Delivery Package Details

• 1 x Emerson EPRO PR6426/010-010 displacement sensor with 1.0 m armored cable
• 2 x M14x1.5 mounting locknuts
• 1 x Individual test and calibration certificate

Field Assembly & Cable Routing Guidelines

Threaded Body Clearance & Insertion

• Ensure tapped mounting holes are clear of foreign particulates prior to threading the M14x1.5 stainless steel casing.
• Provide an unthreaded radial space of minimum 20 mm around the probe tip to prevent side-wall interference on target readings.

Armor Support & Shield Termination

• Secure the flexible stainless steel armoring to non-vibrating structural points using insulated clamps.
• Terminate inner cable shields exclusively at the CON transmitter ground bus to eliminate circulating earth currents.

Frequently Asked Questions

• What primary measurement does the PR6426/010-010 execute?

  The sensor measures static axial position and dynamic shaft vibration relative to rotating machinery targets.

• What does the -010 suffix represent in the order number?

  The -010 suffix specifies an integral 1.0 m stainless steel armored cable attached directly to the sensor head.

• Is the PR6426/010-010 self-powered?

  No, the unit is a passive inductive sensor energized by high-frequency AC excitation generated by the signal converter.

• Can the sensor cable be cut or extended directly in the field?

  No, modifying cable length alters internal capacitance and compromises factory displacement calibration curves.

• What target material is required for standard scale accuracy?

  Factory calibration matches ferromagnetic steel grade 42CrMo4 (equivalent to AISI 4140 steel).

• What is the nominal linear measurement range of this 12 mm probe?

  The transducer features a standard linear displacement span of 4.0 mm across its operational window.

• How are signal ground loops prevented during wiring setup?

  Cable shields must be connected strictly at one single termination point at the processing driver housing.

• What mounting thread pitch is used on the transducer shell?

  The sensor body utilizes standard M14x1.5 outer metric threads along its stainless steel housing.
