The Emerson PR 6424/010-040, also cataloged as the PR 6424/010 Proximity Probe, operates as a dedicated hardware component for non-contact eddy-current displacement and vibration measurement within CON010 signal transmitter systems.

Ordering Code Configuration

• Base Model (PR 6424/010): Non-contact eddy-current proximity sensor with 8 mm tip diameter and M10x1 thread style.
• Cable Length Code (-040): Integrated armor-protected cable length representing 4.0 m total system cable without external extension.

Core Physical & Electrical Data

Eddy-Current Signal Scaling & Gap Voltage Validation

The sensor operates on high-frequency electromagnetic field interaction with conductive target surfaces. Rotor dynamic movement alters the eddy-current field density, generating an impedance shift proportional to shaft position. Connected CON010 signal converters translate this shift into standardized voltage or current outputs with target gap voltages around -10 VDC at mid-range positioning. Cross-talk suppression geometry ensures signal integrity when multiple probes operate in close physical proximity inside bearing housing assemblies.

Package & Delivery Scope

• 1 x Emerson epro PR 6424/010-040 proximity probe assembly with integrated 4.0 m armored cable
• 2 x M10x1 mounting hex nuts
• 1 x Factory calibration data summary sheet

Mechanical Assembly & Installation Directives

Mounting Thread & Clearance Limits

• Thread engagement requires clean M10x1 tapped holes free of metal debris.
• Maintain an unthreaded radial clearance zone of at least 15 mm around the probe tip to prevent side-wall signal interference.

Cable Routing & Shield Grounding

• Route the flexible stainless steel armor clear of high-voltage power lines and rotating shafts.
• Connect cable shielding to the ground terminal at the CON010 signal converter chassis only, avoiding ground loops.

Frequently Asked Questions

• What is the primary function of the PR 6424/010-040 probe?

  It measures non-contact shaft vibration and axial displacement on rotating machinery when paired with a matching converter.

• What does the -040 suffix designate in the part number?

  The -040 suffix designates an integral cable length of 4.0 m measured from probe tip to connector.

• Can the probe cable be cut or shortened on site?

  No, cutting probe cables alters system capacitance and invalidates physical gap and scale calibration.

• What target material is used for standard factory calibration?

  Standard calibration uses ferromagnetic steel grade 42CrMo4 (equivalent to AISI 4140 steel).

• What is the nominal linear measuring range of this probe?

  The probe features a standard linear displacement measuring span of 2.0 mm.

• What voltage output is expected at mechanical center gap?

  The probe converter assembly typically outputs approx -10 VDC at the midpoint of the linear measuring range.

• How should cable shields be terminated to avoid noise interference?

  Shields must be grounded at one end only at the CON010 converter terminal to prevent ground loops.

• Is external electrical power required directly at the probe body?

  No, the probe is a passive inductive sensor driven directly by high-frequency AC excitation from the signal converter.
