Optoelectronic Level Switch - OLS-C20

Brand: WIKA Alexander Wiegand SE & Co. KG

The model OLS-C20 optoelectronic level switches are used for the detection of limit levels in liquids. 

This is widely independent of physical characteristics such as refractive index, colour, density, dielectric constant and conductivity. Measurement is also done in small volumes.
