Physical and Electrical Specifications

Eddy-Current Probe Scaling and Cross-Talk Suppression

The 8 mm reverse-mount transducer configuration relies on precise eddy-current probe scaling to execute radial or axial shaft tracking. Field calibration routines demand exact gap voltage validation (-10 VDC targets) representing the definitive geometric center of the linear voltage window. When mapping high-density layouts for multi-plane rotor dynamics analysis, field technicians must adhere to spacing minimums to ensure absolute cross-talk suppression. Unshielded overlapping radio frequency fields between neighboring tips distort the induction curve and corrupt the monitor logic.

Ordering Package Manifest

Mechanical Alignment Guidelines

• Reverse Mount Fitting: Ensure the mating sleeve or housing adapter threads match the M10 x 1 metric profile exactly before tightening the reverse mount sleeve assembly.

• Gap Voltage Alignment: Spin the probe body into the holder assembly while tracking the sensor loop voltage until reaching the standard target value of -10 VDC.

• Cable Strain Management: Secure the 1.5 m coaxial extension lead with adequate slack to prevent insulation shear or tight bending radius failure at the barrel exit.

• Shield Grounding Boundary: Isolate the outer coaxial jacket braid from machine casing contact, grounding the shield strictly at the Proximitor enclosure barrier.

Engineering FAQ

• What specific electrical parameter signifies that the probe gap is correctly calibrated?

  The electrical field calibration requires adjusting the sensor position until the raw DC voltage at the Proximitor reads -10 VDC, securing the exact midpoint of the linear displacement zone.

• Can this proximity probe component be hot-swapped while the machinery monitor is under power?

  Yes, the probe is a passive transducer and can be decoupled from the cable link while live. However, the sudden voltage drop will trigger rack alarms if bypass locks are not set.

• How does targeting alternative metal substrates affect the factory scale factor?

  The internal eddy-current loop is calibrated exclusively for AISI 4140 steel targets. Testing alternative metals changes the magnetic flux properties, introducing significant scaling calculation errors.

• What specific industrial protection does the -01 connector option suffix offer?

  The -01 option designates a bare miniature coaxial clickloc interface without an external sleeve protector, requiring explicit housing enclosure or separate potting protection.

• Does this hardware module draw direct operational current from the monitoring rack backplane?

  No, the probe contains no active electrical components. It acts as a passive reactive load driven entirely by high-frequency excitation voltage generated by the external Proximitor Sensor.

• What physical spacing is mandatory to ensure complete cross-talk suppression between probes?

  Probes must maintain a minimum physical distance equivalent to at least three tip diameters from any adjacent probe or unexpected structural metal to preserve magnetic field integrity.

• What performance issue occurs if the total cable length is modified outside of specifications?

  The system demands a matching 5.0 m or 9.0 m total system length. Arbitrary cable cutting or extensions throw off the tuned loop impedance, which invalidates the 7.87 V/mm linear scale factor.

• What are the physical temperature boundaries governing the probe tip and internal wire?

  The 8 mm tip structure and matching coaxial lead are structurally rated to withstand field conditions ranging from a minimum of -51 deg C up to a maximum limit of +177 deg C.
