Dexter, Mich.-based SIKO – a division of SIKO GmbH, headquartered in Buchenbach, Germany – has introduced a magnetic measurement system featuring flexible solar thermal collectors that adapt to the position of the sun.
The sensors work according to a magnetic measuring principle, which allows them to move without physical contact, the company explains. The sensors measure the angle of the reflectors, thus providing a downstream control system via a position message.
The required angles (i.e., set value) are stored in the controller according to the time of day and the position of the sun. As the collectors can assume any position, they follow the movement of the sun throughout the day.
The sensors can be used with either power-tower or parabolic-trough collectors, SIKO adds.
