Dwyer OLS-11 OPTICAL LEVEL SWITCH, LED POLYSULFONE WETTED PARTS

  • Compact Size and no moving parts
  • The bright red and green LED’s indicate the presence or absence of liquid for true, local indication.
  • Compact switch can be quickly mounted horizontally or vertically for each installation.
  • The optical level switch employs an LED, which transmits infrared light.
  • This light is sent through a prism and reflected back to a photo-transistor utilizing two 90° light reflections.
  • With the prism surrounded by a gas, the light source is cast back to the photo-transistor.
  • When a translucent liquid is introduced to the prism at or above the point where the light source makes contact with the prism, the light is reflected into the liquid, not allowing the photo-transistor to energize
