Hardware Specifications

Mechanical Monitoring and TSI Characteristics

The transducer utilizes eddy-current probe scaling to convert proximity to target into proportional voltage output. System stability requires gap voltage validation, with typical targets at -10 VDC at the monitor input when at the designated electrical zero. Cross-talk suppression is maintained through integrated coaxial shielding to ensure signal integrity for accurate rotor dynamics analysis, preventing measurement errors in high-speed rotating machinery.

Field Installation Guidelines

• Mechanical Installation

• Ensure a minimum of 5 full thread engagements when mounting into the probe bracket.

• Use locking nuts to secure the probe position relative to the target surface.

• Electrical Termination

• Clean coaxial connector interfaces using non-residue cleaner before mating.

• Ensure the ClickLoc connector is fully engaged to maintain 50 Ohm impedance continuity.

• Grounding

• Maintain a low-impedance ground path between the probe housing and the machine case to avoid ground loop noise.

Frequently Asked Questions

• Is this probe compatible with non-3300 XL monitor systems?

  This probe is calibrated for the 3300 XL transducer system. Usage with legacy monitoring hardware requires verification of compatibility to prevent scaling errors.

• Can the probe cable be field-spliced?

  No. The cable is factory-calibrated to a specific length to maintain 50 Ohm impedance. Splicing will alter the electrical resonance and degrade measurement accuracy.

• What does the -10 VDC gap voltage target represent?

  This is the standard operating voltage for the probe at its calibrated zero-gap position, which allows the system to monitor both positive and negative vibration excursions.

• Is the probe tip sensitive to high temperatures?

  The probe is rated for operation up to 177 deg C. Ensure the installation location does not exceed this rating, as excessive heat will result in non-linear signal output.

• How should the cable be protected during installation?

  Route cables through rigid or flexible metal conduit to prevent mechanical damage, abrasion, or exposure to corrosive lubricants.

• Can the probe be hot-swapped while the machine is running?

  No. Replacing the probe will result in a sensor fault or open-circuit condition, which will likely trigger a machinery protection alarm.

• What is the impact of probe misalignment?

  Misalignment relative to the target surface center can introduce non-linearities and potential signal errors, affecting the quality of the rotor displacement data.

• Is the shield internally grounded?

  The shield is part of the electrical loop. Do not ground the cable shield at any point other than the designated monitor or transducer ground connection.
