Hardware Specifications

Eddy-Current Probe Scaling and Rotor Dynamics Tracking

The integrated 8 mm sensing tip applies automated eddy-current probe scaling to convert magnetic flux deviations into linear voltage variations. This architecture supports precise rotor dynamics monitoring across machinery casings while maintaining rigorous cross-talk suppression between neighboring channels. Furthermore, the internal signal conditioning loop guarantees consistent gap voltage validation targets during continuous high-frequency vibration recording.

Field Installation Guidelines

• Thread Engagement and Sealing
  • Apply approved thread sealant compatible with industrial process environments to the 3/4-14 NPT threads before insertion.
  • Engage a minimum of 5 full thread turns into the machinery mounting port to secure the assembly against high vibration loads.
• Conduit Routing and Bending Limits
  • Route the 2-inch armored conduit along rigid structural channels, keeping it isolated from high-voltage motor cables.
  • Maintain the manufacturer-specified minimum bend radius along all conduit curves to protect internal wiring profiles.

Engineering Technical FAQ

• What nominal supply voltage range is required to power the self-contained PROXPAC XL assembly?

  The internal integrated Proximitor circuit operates on a direct current supply voltage ranging from -17.5 VDC to -26 VDC.

• What maximum current draw does this self-contained transducer assembly exhibit during normal operation?

  The internal conditioning electronics draw a maximum current of 12 mA under standard operational loops.

• How does the 15-inch insertion depth affect physical positioning inside machine housings?

  The 15-inch probe insertion length dictates the physical standoff distance of the sensing tip from the outer mounting boss to the target shaft.

• What specific incremental scale factor output is produced by the integrated 8 mm probe circuit?

  The assembly generates a standardized incremental scale factor output of 7.87 V/mm across its active linear range.

• Can this self-contained unit operate without an external standalone Proximitor module?

  Yes, the PROXPAC XL design incorporates the Proximitor sensor directly into the housing assembly, eliminating the need for a separate remote module.

• What frequency response bandwidth does the internal signal processing loop support?

  The transducer path supports a frequency response bandwidth ranging from 0 Hz up to 10 kHz for dynamic vibration tracking.

• What is the defined output resistance value for the signal transmission line?

  The signal output line maintains a fixed output resistance of 50 Ohm to match standard monitoring instrument inputs.

• How does the 3/4-14 NPT thread standard impact mechanical mounting procedures?

  The NPT tapered thread profile provides a mechanical seal directly into the equipment tapping without requiring a separate gasket adapter.
