FREQUENTLY ASKED QUESTIONS
Selection and Installation Checks
|
| Q1 |
What does the probe measure?
It measures relative shaft displacement without mechanical contact and supports vibration, position, eccentricity and speed applications.
|
| Q2 |
Can the probe work alone?
No. It forms a calibrated measuring chain with the correct converter and total cable length.
|
| Q3 |
Can another PR6423 suffix be installed directly?
Do not assume interchangeability. Match probe geometry, connector, cable length, converter and machine mounting.
|
| Q4 |
What must be checked during installation?
Confirm target material, initial gap, bracket rigidity, cable routing and connector protection.
