TED - Optical Level Sensor From Kobold Instruments
The TED - Optical Level Sensor for liquids series is the solution to your difficult level switching needs. This device operates independently of liquid properties such as color, viscosity, dielectric constant, density, conductivity, contamination, and temperature.
Should your application require higher power switching capability, a 10 amp relay output is available through use of the RL-5900 power supply/relay module.
