Hardware Specifications

TSI and Mechanical Dynamics

The 3300 series utilizes eddy-current probe scaling to convert target proximity into electrical signals. Linearity is maintained through gap voltage validation, with -10 VDC targets required to center the probe within its operational range. To ensure accurate rotor dynamics data, the system employs cross-talk suppression by adhering to specified spacing requirements in multi-probe arrays. Proper installation requires verification of target surface diameter to eliminate field edge effect errors, which otherwise manifest as non-linear measurement behavior.

Installation Guidelines

• Mechanical Mounting: Thread the probe into the M8 x 1 mounting aperture, ensuring sufficient engagement to prevent loosening from machine vibration.

• Connector Engagement: Tighten the ClickLoc connector until the locking mechanism is fully seated to maintain signal impedance integrity.

• Grounding: Secure the coaxial cable shield at the Proximitor sensor ground terminal to eliminate ground loops.

• Calibration: Use a digital voltmeter to verify a -10 VDC gap voltage during static machine conditions to ensure the probe tip is centered.

Frequently Asked Questions

• Can this probe be used without a Proximitor sensor?

  No. This probe is a passive component and requires a matched 3300 series Proximitor to condition the eddy-current signal for system output.

• Is the cable length field-modifiable?

  No. The system is factory-calibrated for a 1.0 m length; modifying the cable alters circuit impedance and invalidates the measurement accuracy.

• What is the consequence of exceeding the linear range?

  Exceeding the linear range results in signal clipping and non-linear response, leading to invalid vibration amplitude and position data.

• Are the ClickLoc connectors water-tight?

  The connectors provide a secure mechanical interface but require additional environmental protection if installed in locations subject to direct fluid spray.

• Can the probe withstand high-temperature environments?

  Yes. The probe is designed for operation up to 177 deg C, provided the coaxial cable dielectric and connector are similarly rated for the application.

• Does the probe require specialized grounding?

  The probe body is grounded via the machine casing; ensure the mounting threads are free of insulating paint or coatings to maintain electrical continuity.

• What causes signal drift during operation?

  Signal drift is typically caused by variations in gap voltage or thermal expansion of the probe mounting assembly, requiring periodic system verification.

• Are the grommets in the installation kit reusable?

  Grommets are designed for a single compression cycle. If the probe is reinstalled, inspect the grommets for deformation and replace if necessary.
