Hardware Specifications

Rotor Dynamics and Gap Voltage Validation

• Eddy-current probe scaling translates mechanical shaft displacement relative to the probe tip directly into precise electrical signals.
• Proper system calibration requires gap voltage validation to ensure the static operating point achieves the -10 VDC target within the linear range.
• Rotor dynamics analysis depends on the high-frequency response of the ETR reverse mount probe configuration to track transient vibrations accurately.
• Cross-talk suppression properties prevent mutual signal interference when multiple sensing channels are installed closely on machine housings.

Mechanical Installation Guidelines

• Mount the probe using the reverse mount configuration into the designated machine casing port, ensuring secure thread engagement.
• Route the short integral coaxial cable carefully to avoid sharp bends that could compromise impedance and shielding integrity.
• Protect connector interfaces from moisture and particulate contamination during physical installation inside machinery enclosures.
• Terminate the signal shield exclusively at the monitoring instrumentation rack ground to eliminate disruptive ground loops.

Technical FAQ

• What is the nominal scale factor for this proximity transducer model?

  The incremental scale factor is calibrated to 7.87 V/mm across the standard linear measuring range.

• What operating temperature range is supported by the ETR design?

  The probe withstands extreme environmental temperatures ranging continuously from -51 deg C to +177 deg C.

• How should the static gap voltage be adjusted during initial setup?

  The gap voltage must be adjusted to -10 VDC using a digital multimeter connected to the Proximitor sensor output.

• Can the integral cable length be modified or shortened on-site?

  Field cutting or splicing alters electrical resonance and voids factory calibration accuracy.

• What thread profile does this reverse mount probe utilize?

  The unit incorporates a specialized thread structure engineered specifically for reverse mount installation requirements.

• Does this probe require an independent power source?

  No, it operates passively and receives excitation voltage through the connected Proximitor sensor unit.

• What is the linear measurement range of the 8 mm probe tip?

  The linear measurement span covers 2.0 mm centered symmetrically along the response curve.

• How is signal integrity preserved against external electromagnetic interference?

  An outer metallic braid and robust protective fluorocarbon jacket encase the high-frequency coaxial line.
