Hardware Specifications

Rotor Dynamics and Transducer Measurement Mechanics

• Eddy-Current Probe Scaling: High-frequency radio frequency circuitry excites the probe coil, generating a linear voltage output directly proportional to the air gap distance between the sensor tip and the conductive rotating shaft target.
• Gap Voltage Validation: Technicians must verify that the initial static operating point achieves exactly -10 VDC using a calibrated multimeter during mechanical alignment to guarantee full linear dynamic range.
• Cross-Talk Suppression: Spatial isolation and high-frequency modulation design prevent electromagnetic interference when multiple proximity probe assemblies are installed adjacently on shared machinery casings.
• Rotor Dynamics Monitoring: Translates mechanical shaft radial vibration, axial position displacement, and speed changes into high-fidelity electrical inputs for continuous machinery protection monitors.

Field Installation Guidelines

• Thread Engagement: Secure the M10 x 1 threaded probe body into the machinery casing, ensuring correct thread engagement and torque to prevent operational loosening.
• Physical Gap Setting: Adjust the mechanical distance between the probe tip and the shaft surface to yield a 1.27 mm (50 mils) air gap, targeting a stable -10 VDC output.
• Cable Routing: Route the integral coaxial cable away from high-voltage motor leads and variable frequency drives, utilizing protective conduits where necessary.
• Grounding Compliance: Ensure shield continuity is maintained through the monitoring loop to prevent extraneous electromagnetic noise interference.
