Cross-Talk Suppression & Gap Voltage Validation

The 3300 NSv proximity probe utilizes high-frequency radio frequency energy to detect static distance and dynamic vibration of conductive target surfaces. Designed specifically for tight side-clearance target areas, the probe tip design minimizes side-view magnetic field dispersion, ensuring effective cross-talk suppression when probes are mounted in close proximity on small shafts or gear sets. Calibration and verification require performing gap voltage validation at the Proximitor Sensor terminals, adjusting the physical position until reaching a standard baseline target of -10 VDC under non-rotating shaft conditions.

Frequently Asked Questions

Q: What is the maximum tightening torque specified for mounting the stainless steel probe body?

A: The probe should be tightened by hand, with a strict maximum tightening torque limit of 0.56 N m to avoid damage to the threaded casing.

Q: What precautions should be taken regarding low temperature exposure?

A: Although the working and storage range spans from -52 to 177 deg C, prolonged exposure to cold temperatures below -34 deg C should be avoided to prevent stress on cable materials and potting compounds.

Q: What connector protection is supplied with the probe assembly?

A: The probe is shipped in original factory packaging and includes protective caps over the miniature coaxial ClickLoc connector to prevent contamination before field mating.

Field Installation Guidelines

  1. Physical Thread Engagement: Thread the M10x1 stainless steel case into the tapped mounting port, ensuring thread depth does not exceed 15 mm.
  2. Hand Tightening: Tighten the probe body by hand only. Do not exceed the maximum allowable torque specification of 0.56 N m.
  3. Gap Voltage Calibration: Adjust axial positioning while reading the DC terminal output at the connected Proximitor until achieving the target -10 VDC gap setting.
  4. Coaxial Connection: Remove the protective cap and connect the ClickLoc coaxial connector to the extension cable, verifying that the lock fully latches against vibration.
