Hardware Specifications

Mechanical Monitoring and TSI Characteristics

The 330709 transducer relies on precise eddy-current probe scaling to ensure linear displacement output. During system integration, gap voltage validation is required to calibrate the -10 VDC target, ensuring the output rests within the linear range of the Proximitor sensor. Proper installation is necessary to mitigate rotor dynamics influences and ensure cross-talk suppression by maintaining specified physical clearances from adjacent probes and conductive mounting structures.

Frequently Asked Questions

Q: Can this 1.0 m system length be extended using standard coaxial cables?

A: No, the system length is calibrated as a complete set (Probe, Extension Cable, and Proximitor). Modifying the total cable length alters the impedance and affects the signal linearity and frequency response.

Q: Is the ClickLoc connector compatible with older 3300 series probe connectors?

A: No, the ClickLoc connector system is specific to the 3300 XL series. It utilizes a locking mechanism that provides superior mechanical security against vibration compared to older screw-style connectors.

Field Installation Guidelines

• Mounting: Ensure the probe is mounted perpendicular to the target surface. Utilize the M16 x 1.5 threads for secure positioning, observing torque limits to prevent casing deformation.
• Cable Integrity: Maintain the cable bend radius specification to prevent damage to the internal coaxial structure, which can cause erratic gap voltage readings.
• Grounding: The probe casing must be electrically connected to the machine frame to ensure proper shielding against electromagnetic interference.
• Clearance: Maintain a minimum clearance from surrounding structures to avoid signal interference. Verify the gap voltage at the Proximitor output using a digital voltmeter during the installation phase.
