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 sensor channels are installed adjacently on shared machinery panels.
• 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

• DIN-Rail and Panel Mounting: Secure the Proximitor sensor securely to a grounded panel or DIN-rail using appropriate mechanical fasteners, ensuring isolation from high-voltage wiring paths.
• Signal Wiring Terminations: Connect shielded signal cables directly to monitor input channels, ensuring the outer shield is grounded strictly at one end to prevent ground loops.
• Power Supply Verification: Confirm that the rack power supply delivers a stable negative DC voltage between -17.5 VDC and -26 VDC prior to energizing the measurement loop.
• Gap Voltage Check: Adjust probe physical depth until the Proximitor output voltage registers a stable -10 VDC initial static operating point.
