OPASTOP GP3000T: définition of the system
Measuring unit (Receiver)
A cone of modulated light is emitted
from a light source module.
A receiver positioned at 90° to the
light source unit receives part of the
reflected light from the suspended
particles.
A sweeping air system enables the
fibre optic tips to stay clean.
