Hardware Specifications

Mechanical Monitoring & TSI Properties

The probe facilitates eddy-current probe scaling for accurate gap measurement between the sensor tip and the observed rotating component. Accurate gap voltage validation is required to ensure the system output maintains a nominal -10 VDC target at the center of the linear range. Precise installation is required to manage rotor dynamics and ensure that signals are not influenced by improper mounting or potential cross-talk suppression issues arising from proximity to other sensor probes or metallic structural elements.

Field Installation Guidelines

• Mounting: Ensure the M14 x 1.5 thread is engaged securely in the mounting bracket; avoid overtightening to prevent structural deformation of the probe case.
• Gap Setting: Adjust the probe distance using a feeler gauge to achieve the specified initial gap voltage, typically centered around -10 VDC.
• Grounding: Ensure the sensor tip is isolated from the mounting bracket if the system design requires electrical isolation to prevent ground loops.
• Routing: Route the miniature coaxial cable away from high-current power cables to prevent electromagnetic noise interference in the signal path.

Frequently Asked Questions

• What is the purpose of the 11 mm tip diameter?

  The 11 mm diameter provides an extended linear range compared to 5 mm or 8 mm probes, suitable for monitoring applications requiring larger displacement coverage.

• Can the cable be field-repaired if cut?

  Field repair of the coaxial cable is not recommended as it alters the impedance and affects the calibrated accuracy of the proximity system.

• What happens if the gap voltage exceeds -10 VDC?

  If the gap voltage drifts outside the specified range, the monitoring system may trigger an alarm or indicate a fault due to the signal approaching non-linear regions.

• Is the ClickLoc connector compatible with standard BNC?

  The ClickLoc connector is a proprietary design; use only compatible extension cables to maintain signal integrity and connection reliability.

• Does the probe require a specific proximity housing?

  The M14 x 1.5 thread requires a matching threaded bore or bracket to ensure proper axial alignment with the rotating shaft surface.

• Can the probe operate in high-temperature environments?

  The probe is engineered for operation up to 177 deg C; ensure the selected cable and connector are also rated for the environment.

• How should the probe be tested after installation?

  Perform a static gap test by varying the distance to a target material and measuring the output voltage to verify the probe's sensitivity.

• Is the probe sensitive to target material?

  The proximity system is calibrated for a specific material (typically 4140 steel); using a different target material will necessitate a scaling factor adjustment.
