More Information

Overview Manuals Applications Installation Environmental Ratings Compatibility & Interoperability

Features:

  • Measures non-contact shaft displacement with an 8 mm eddy current probe and two-millimetre range.
  • Uses a reverse-mount 3/8-24 UNF body where rear access is required.
  • Pairs a five-metre LEMO cable configuration with the CON021 linearizing converter.
The full option code specifies reverse mounting, inch thread, cable construction and adapter arrangement.

It converts the changing probe-to-shaft gap into a dynamic voltage for vibration or position monitoring.

Mechanical fit and electrical calibration must be checked together because probe cable and converter are part of the measuring system.

Verified resources for Emerson PR6423/10R-010 CON021: Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Steam-turbine bearing housings use the reverse-mount probe where the approach to the shaft is from inside the machine structure.
  • Compressors monitor radial vibration by resolving rapid shaft motion without physical contact.
  • Machinery-protection racks use the converter signal for alarms, trips and trend analysis of rotor behaviour.
  • The reverse-mount 3/8-24 UNF body requires rear access and a suitable threaded bracket.
  • A static initial gap of about 0.5 mm places the shaft within the calibrated two-millimetre range.
  • The supplied five-metre cable path should not be shortened, extended or tightly coiled outside installation guidance.
  • The probe assembly carries an IP66 protection rating when installed with the specified connections.
  • The probe and first metre of cable are rated from -35 to 180 °C.
  • Connector and remaining cable sections must remain within their lower -35 to 150 °C temperature limit.
  • CON021 provides the linearized output expected by compatible EPRO machinery-protection electronics.
  • Calibration is referenced to a 42CrMo4 or AISI 4140 steel target and changes with other materials.
  • Probe option code, total cable length and converter range must match as one transducer system.
Description
PR6423/10R-010 CON021 combines a reverse-mounted, non-armoured probe with the converter used for the standard two-millimetre measuring range. Its adapter-plug and five-metre LEMO-terminated cable configuration is defined by the complete option code.

The converter excites the probe coil and linearizes the change in impedance produced by conductive shaft motion. A proportional negative-voltage output is then available to turbine supervisory or machinery-protection electronics.

Probe thread, reverse-mount clearance, total cable length, target material and initial gap all influence calibration. The probe and converter should therefore be treated as a matched system rather than substituting a visually similar PR6423 variant.

What mounting feature distinguishes Emerson PR6423/10R-010 CON021?
The 10R body is the reverse-mount execution with a 3/8-24 UNF thread.
Which cable arrangement belongs to Emerson PR6423/10R-010 CON021?
The option code identifies an unarmoured probe with adapter plug, five-metre total cable and LEMO end.
Where is Emerson PR6423/10R-010 CON021 most useful?
It suits radial shaft monitoring where the probe must be secured from the reverse side of the mounting structure.
Why should the CON021 remain matched to Emerson PR6423/10R-010 CON021?
The converter and complete cable length establish the excitation and linearization for the calibrated range.
What mechanical data must be checked before replacing Emerson PR6423/10R-010 CON021?
Confirm thread, reverse-mount access, shaft material, target diameter, bracket position and initial gap.
Which transducer identifiers prevent a mismatch for Emerson PR6423/10R-010 CON021?
Use the complete probe and converter designation, quantity, target material and delivery destination.
