Abstract
We present a calibration method for an inductive localization system used to trace wireless sensors for the future use in photoreactors. Photoreactors are used to cultivate photosynthetic active microorganisms and cells or to perform photocatalytic reactions. Due to the limited penetration depth of light inside those reactors, a novel internal illumination system have been presented in past. The illumination system consists of so called Wireless light emitters (WLE) which are small glowing spheres floating around in the reactor. The WLE are powered through an inductive link where the driving coils are placed at the outer diameter of the reactor. They produce an intermediate frequency (178 kHz) electromagnetic field with a magnetic flux density of approx. B = 1 mT [1] - [3]. The next step in this project is the inclusion of sensors for measuring various parameters inside the reactor. Additionally, the information about the sensor position leads to a spatial resolution of the measured quantity. Therefore, wireless sensors are needed as well as a suited localization method.
