Hardware Specifications

Eddy-Current Probe Scaling and Rotor Dynamics Tracking

The Proximitor unit emits a high-frequency carrier signal to drive connected proximity probes, executing precise eddy-current probe scaling to convert physical gap displacements into linear voltage values. This conditioning loop maintains rigorous cross-talk suppression between channels and enforces strict gap voltage validation (-10 VDC targets) during continuous rotor dynamics monitoring across rotating machinery.

Field Installation Guidelines

• Enclosure Mounting and Grounding
  • Secure the A308 aluminum housing firmly onto the structural panel or DIN mounting track within the machinery protection cabinet.
  • Ensure proper low-impedance electrical bonding between the enclosure chassis and the instrument rack ground bus to eliminate ground loops.
• Signal and Power Wiring Protocols
  • Connect the negative power supply lead to the designated terminal while maintaining loop voltage within the -17.5 VDC to -26 VDC range.
  • Route coaxial output signal lines separately from high-voltage AC motor power cables to prevent induced electrical noise.

Engineering Technical FAQ
