Laser Flow Sensor for Lubricating Oil

Michele Norgia, Alessandro Pesatori
  • Abstract:
    This work describes the development of a laser instrument for measuring the flow speed of oil, for minimum-quantity lubrication. The sensor is the laser diode itself, placed on the oil tube without any lens, acting as a self-mixing interferometer. The dyes inside the oil induce a back scattering of the emitted light, and generate a Doppler signal, measured by the laser monitor photodiode. Through a suitable elaboration of the signal spectrum, it is possible to estimate the oil flow; this measurement is essential for the correct maintainability of machine tools.
