Optical Level Switch (SERIES OLS)
series ols optitrol optical level switch
low cost, compact, led indication, no moving parts
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 leds 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.
principles of operation
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.

RS-485 Serial Communications Module
Model TS485 RS-485 Serial Communications Module
Connects to Configuration Key Port
The MODEL TS485 Serial Communications Module allows users to read the current temperature and parameter settings of the Love Controls family of temperature switches. The configuration key port on the temperature switch provides the data signal and power for the RS-485 module. For applications with multiple temperature switches, the modules can be daisy chained together so that only two wires need to be brought to the PC. The Model TS485 is compatible with Series TS3, TSX3, TCS, TS2, TSS2, TSW.
Features:
Field configurable RS-485 communication
Applications:
Refrigerated cabinets
Walk in coolers
Food service equipment
Medical sterilizers or equipment
Wood or pellet boilers
Brewing systems
