Optical Level Switch Model OLS
Low Cost, Compact, LED Indication
Low cost, rugged optical level switch provides rapid response while employing no moving parts for stable process control. The bright red green LED's indicate the presence or absence of liquid for true, local indication. For application flexibility, this level control utilizes FDA approved materials. Compact switch can be quickly mounted horizontally or vertically for each installation.
