FAQ
-
What type of signal does the 21500-00-12-05-02 probe output?
The probe outputs an AC voltage signal proportional to the displacement of the target. -
What is the linearity specification of this probe?
The linearity is ±1% of full-scale measurement. -
What is the operating temperature range?
The probe operates reliably between -40°C and +120°C. -
Can this probe handle harsh chemical environments?
The stainless steel housing provides good resistance to most industrial chemicals, but compatibility should be checked for highly aggressive substances. -
What is the typical response time for the probe?
Response is instantaneous for shaft vibration frequencies up to the rated frequency of the 7200 system. -
Is the probe suitable for high-speed rotors?
Yes, it is optimized for high-speed machinery and can monitor rotor vibrations accurately. -
