Hardware Specifications

Eddy-Current Probe Scaling and Rotor Dynamics Integration

The 10030-05-30-05-02 proximity probe generates a high-frequency electromagnetic field at its tip to support eddy-current probe scaling when matched with a Series 10000 Proximitor Sensor. As the target surface moves within the probe's magnetic field, induction changes alter the transducer loop impedance. The resulting variations are output as an analog voltage directly proportional to the physical gap, serving as an input for monitoring complex rotor dynamics such as radial shaft vibration, thermal growth, and axial thrust displacement.

To secure accurate measurement limits, proper gap voltage validation (-10 VDC targets) must be verified during installation. With the probe positioned near the midpoint of its linear range, the DC gap voltage at the Proximitor output is set to -10 VDC. Proper calibration alignment ensures a stable scale factor of 200 mV/mil and optimizes cross-talk suppression when multiple 5 mm probes are mounted within close axial proximity.

Field Installation Guidelines

• Verifying Radial Clearance and Positioning

  Ensure a minimum radial clearance of 7.6 mm (0.30 in) from any adjacent metal casing to prevent shielding errors. Hand-thread the metric body carefully into the mounting tap to avoid damage to the M10 x 1.0 threads.

• Connector Protection and Ground Isolation

  The miniature coaxial connector must remain completely dry and isolated from the machine housing. Protect the mated coaxial connection with an insulating sleeve to prevent ground loops.

• Impedance-Safe Cable Routing

  Avoid routing the integrated 0.5-meter cable adjacent to high-current conduit. Secure the cable with a minimum bend radius of 25.4 mm (1.0 in) to preserve signal integrity and internal impedance.

Frequently Asked Questions

• How is the physical target gap calibrated during field setup?

  Adjust the probe depth in the mounting tap until the DC gap voltage at the Proximitor output reads -10 VDC.

• Is this metric probe interchangeable with standard 3/8-24 UNF threaded systems?

  No, the physical threads are metric M10 x 1.0. Attempting to force-fit this into a UNF tapped hole will destroy the threads.

• What occurs if the physical cable bend is tighter than 25.4 mm?

  Severe bends compress the internal dielectric, changing the coaxial impedance and generating electrical noise in the vibration readings.

• Can this probe be connected directly to a 3300 XL Proximitor?

  No, Series 10000 5 mm probes are designed for use with their corresponding Series 10000 Proximitors and extension cables.

• What is the standard target material calibration for this probe?

  Standard calibration is matched to AISI E4140 steel targets. Using other metal alloys requires recalibration of the scale factor.

• Is the probe assembly rated for continuous use above 100 deg C?

  Yes, this model supports an extended operating temperature range up to +150 deg C when used within rated limits.

• Does this passive sensor require independent power wiring?

  No, the probe is passive and draws its operating loop voltage from the -18 VDC to -26 VDC supply provided by the remote Proximitor.

• What happens to the monitor rack channel if the coaxial connector is unplugged?

  The monitoring system will immediately register an open-circuit loop fault, triggering a "Not OK" status and disabling alarms.
