Rotor Dynamics and Eddy-Current Probe Scaling
Eddy-current probe scaling operates on an optimized magnetic field coupling calibrated to 7.87 V/mm (200 mV/mil) output scaling over an 80 mil linear range. Achieving accurate gap voltage validation (-10 VDC targets at center gap) requires proper physical clearance between the smooth case body and surrounding machine housing. Proper spatial orientation and distance from adjacent probe tips ensure cross-talk suppression during high-speed rotor dynamics measurements on shaft journals.
Frequently Asked Questions
Q: What mounting hardware is required for the 330140 smooth case probe?
A: Because the probe lacks external casing threads, it requires external smooth-bore mounting clamps, bushings, or set-screw mounting blocks to secure the casing in position.
Q: How is the physical gap voltage verified during installation?
A: Connect a multimeter to the associated Proximitor Sensor output terminals and physically adjust the probe insertion depth in its smooth mounting clamp until obtaining a reading of -10 VDC.
Field Installation Guidelines
- Inspect the mounting clamp bore to ensure it is clean and burr-free before inserting the smooth stainless steel case.
- Position the probe tip near the target shaft and measure the DC voltage output at the Proximitor Sensor, adjusting physical insertion depth until achieving -10 VDC.
- Tighten the smooth mounting clamp evenly to prevent crushing or deforming the stainless steel case body.
- Maintain a minimum cable bend radius of 25.4 mm (1.0 inch) along the 1.0-meter coaxial cable run to prevent conductor damage.
- Push the miniature coaxial ClickLoc connectors firmly together until a tactile snap confirms engagement, then insulate the connection using connector protectors or self-fusing silicone tape.
