Hardware Specifications

Rotor Dynamics and Signal Integrity

The 3300 XL 8 mm transducer system utilizes an eddy-current probe scaling to convert target distance into an electrical signal. Accurate data acquisition requires precise gap voltage validation, with a standard -10 VDC target representing the center of the linear measurement range. To maintain signal fidelity in multi-channel installations, cross-talk suppression is achieved by following minimum spacing guidelines to prevent interference between adjacent probes utilizing the same carrier frequency.

Installation Guidelines

• Mechanical Mounting: Secure the probe using appropriate hardware; ensure the probe tip does not contact the rotating target surface to prevent damage.
• Cable Routing: Route the 1.0 meter coaxial cable through grounded steel conduit to minimize external electromagnetic interference.
• Connection: Ensure the ClickLoc connector is fully seated and secured with the provided protector to maintain environmental sealing.
• Gap Verification: Use a high-impedance digital multimeter to confirm the -10 VDC gap voltage at the monitor terminal block after installation.

Frequently Asked Questions

• Is the probe calibration dependent on cable length?

  Yes, the 3300 XL system is calibrated as a matched set; the 1.0 meter cable is integral to the system impedance and cannot be modified in the field.

• What is the role of the 05 agency approval suffix?

  This indicates the probe meets international standards for operation in hazardous locations, including CSA, ATEX, and IECEx certifications.

• How should the probe be grounded?

  The probe case is grounded through the mounting bracket; ensure the bracket maintains a low-impedance path to the machine frame for proper signal referencing.

• What is the maximum linear measurement range?

  The 8 mm probe system is designed for a linear measurement range of 2 mm (80 mil).

• How do I troubleshoot an erratic signal?

  Check for loose cabling, verify the probe gap voltage is within the linear range, and inspect the coaxial connector for oxidation or moisture ingress.

• What is the purpose of the connector protector?

  It seals the miniature coaxial connection to prevent contamination by oil, moisture, or metallic debris in the industrial machine environment.

• Is this probe compatible with all 3300 XL Proximitors?

  The probe must be paired with a Proximitor calibrated for the specific system length to ensure correct frequency response and signal scaling.

• What happens if the operating temperature is exceeded?

  Temperatures above +177 deg C will cause thermal degradation of the probe coil insulation, leading to signal drift or permanent loss of accuracy.
