The graduate achieves the aim in the region of the quantity sensors and method of the electrical and non-electrical quantities measurement. He will learn about the conversion of the non-electrical quantities to electrical ones and he obtains the knowledge of the processing this signal by the computers. He acquires the application possibilities and tendency in the measurement techniques too.

Extent and forms are specified by guarantor’s regulation updated for every academic year.
