Hardware Specifications

Mechanical Monitoring & TSI Properties

The probe facilitates eddy-current probe scaling to convert proximity to conductive targets into linear voltage outputs. Precision performance requires strict gap voltage validation to maintain -10 VDC targets at the center of the linear range. Effective installation must incorporate cross-talk suppression by maintaining specified physical separation between adjacent probes, ensuring that rotor dynamics signals remain free from electromagnetic interference or signal beating caused by proximity to structural components.

Field Installation Guidelines

• Mounting: Thread the probe into the mounting bracket; ensure the jam nut is tightened to prevent axial drift due to machine-induced vibration.
• Gap Setting: Adjust the probe-to-target gap using a feeler gauge to achieve the nominal gap voltage required by the Proximitor sensor calibration.
• Grounding: Maintain electrical isolation between the probe case and the mounting bracket unless the specific installation requires a common ground configuration.
• Cabling: Secure coaxial cabling at regular intervals to prevent mechanical strain on the ClickLoc connector and minimize exposure to high-temperature gradients.

Frequently Asked Questions

• How is the unthreaded length utilized?

  The 4.6 in unthreaded length allows for deep insertion into machine casings where the mounting bracket is offset from the target measurement surface.

• What is the significance of the Agency Approvals?

  The CSA, ATEX, and IECEx approvals certify the device for safe operation in explosive or hazardous industrial environments; refer to control drawings for installation requirements.

• Can the probe be used without the ClickLoc connector?

  The connector is an integral part of the transducer system; removing it will alter the electrical impedance and invalidate the system calibration.

• Is the probe sensitive to electromagnetic noise?

  While shielded, the coaxial assembly should be routed away from high-power AC lines to prevent induced noise in the low-level signal path.

• What if the gap voltage is outside the -10 VDC target?

  A gap voltage shift typically indicates either mechanical movement of the probe or a change in the target material proximity; verify the physical gap immediately.

• Does this probe require a specific extension cable?

  This probe is part of the 3300 XL system and must be mated with a compatible extension cable that matches the total system length requirements.

• Can the probe be used to monitor axial position?

  Yes, this 8 mm probe is frequently used for axial position (thrust) measurements by monitoring the position of a shaft collar or shoulder.

• What is the function of the connector protector?

  The protector prevents moisture, dust, and debris from entering the coaxial connection point, ensuring signal integrity in harsh environmental conditions.
