Anderson, OLS-11, Series OLS Optical Level Switch, Polysulfone Wetted Materials Low Cost, Compact, LED Indication, No Moving Parts Low cost, rugged optical level switch provides rapid response while employing no moving parts for stable process control

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

Product Applications Food and beverage systems Liquid holding tanks Hydraulic reservoirs Sumps Pharmaceutical systems Air conditioning systems Features Compact Size LED Switch Indication No Moving Parts

Principles of Operation The optical level switch employs an LED, which transmits infrared light

With the prism surrounded by a gas, the light source is cast back to the photo-transistor

Compact switch can be quickly mounted horizontally or vertically for each installation

The bright red and green LED’s indicate the presence or absence of liquid for true, local indication

This light is sent through a prism and reflected back to a photo-transistor utilizing two 90° light reflections
