自動粘度計測量時間原理-液體液面光電傳感
Optoelectronic sensing of the liquid meniscus液體液面光電傳感
The near-infrared
light which is generated in LEDs located
in the upper section of the measurement stand is conducted
through a glass-fibre light-conductor cable
onto the measurement planes. The
light shines through the
viscometer before it arrives at another light-
conductor cable located
on the opposite side; inside
this second cable,
the light is conducted
to a receiver in
the upper
section of the measurement stand.
While the liquid meniscus passes through the measurement planes, the lens -like
effect of the meniscus
causes a short-term darkening of the light beam, followed by a
magnification. This
process generates a measurement signal which can be evaluated
accurately.
自動粘度計測量時間原理-液體液面光電傳感
測量位的上部的LED所產生的近紅外光通過玻璃纖維光導電纜進行到測量平面。通過粘度計的光線照射之前它到達位于相反側的另一輕型芯電纜;此**電纜內時，光被在測量臺的上面部分傳導到一個接收器。
而液體彎月面通過測量平面中，透鏡式的彎月面的作用下會導致光束瞬時變暗，接著就變大。這個過程產生能夠**地進行評估的測量信號。
