Series OLS Optitrol Opitcal Level Switch
Brand: Dwyer Instruments, LLC
The Series OLS Optical Level Switches are a low cost, rugged optical level switch that indicates the presence or absence of liquid via infrared light that is reflected back through the prism lens.
It also provides rapid response while employing no moving parts for stable process control.
The bright red and green LED’s indicate the presence or absence of liquid for true, local indication.
Three optional materials, 316 SS, polysulfone and PFA provide application flexibility.
Compact switch can be quickly mounted horizontally or vertically for each installation.
