Tachometer COFRAC calibration
Products
Information
AEROMETROLOGIE can calibrate tachometers (optics, mechanics and linear) and stroboscopes and centrifuges.
The reference velocity is obtained :
in optic, by a generator low frequency coupled to a photoelectric device
in mechanic, by a frequency measurement transmitted by an incremental converter
in linear, same as in mechanic, with moreover the tachometer wheel diameter taken into account
For the stroboscopes, the flash number is read by a photoelectric cell coupled to a frequency measure.
For the centrifuges, the rotation speed is read by a phot-reflexion tachometer and the time is measured by a master chronometer.
Accreditation:
Time-Frequency N°2-1849.
