Hardware Specifications

Eddy-Current Probe Scaling and Rotor Dynamics

The internal oscillator demodulator circuitry drives the probe tip coil with a high frequency radio frequency signal to generate an electromagnetic field interacting with the conductive shaft target. This physical coupling converts mechanical shaft displacement and vibration into a proportional voltage output signal. The circuit maintains rigorous scale factor linearity and supports accurate gap voltage validation against standard -10 VDC targets to evaluate radial shaft position and dynamic rotor behavior.

Mechanical Mounting and Wiring Protocols

• Secure the sensor housing inside an approved protective enclosure or vibration rack junction box away from direct mechanical shock and heavy moisture.
• Maintain the strict minimum cable bend radius of 25.4 mm during field routing to prevent internal coaxial conductor damage or impedance distortion.
• Terminate the coaxial Triax cable shield exclusively at the monitor input or safety barrier to preserve electromagnetic interference suppression.
• Route signal cables away from high voltage alternating current power lines to eliminate induced electrical noise in the monitoring loop.

Frequently Asked Questions

• What is the nominal voltage output scale factor for this sensor system?

  The standard scale factor is 7.87 V/mm (200 mV/mil) across the linear operating measurement range.

• How does the agency approval option impact hazardous area deployment?

  The -05 suffix provides factory-certified CSA, ATEX, and IECEx ratings for safe installation in explosive industrial atmospheres when paired with appropriate barriers.

• Can extension cables of different lengths be substituted in the field?

  No, the extension cable length must strictly match the designated system length code to ensure calibration accuracy and frequency response.

• What purpose does the MOD 145193-01 designation serve?

  It indicates a custom factory modification applied to the standard hardware configuration for specific application requirements.

• What is the required DC input voltage range for proper operation?

  The unit requires an external power supply ranging from -17.5 VDC to -26 VDC delivered through the monitor channel.

• How is initial gap voltage adjusted during mechanical commissioning?

  The mechanical gap between the probe tip and shaft is adjusted until the monitoring system reads a nominal -10 VDC center position voltage.

• Which material forms the primary construction of the probe tip?

  The tip is manufactured from robust polyphenylene sulfide to resist aggressive lubrication fluids and high thermal environments.

• What precautions must be taken with coaxial connectors?

  All connectors must remain clean, dry, and free from oil or particulate contamination during coupling to avoid signal attenuation.
