Radiofrequency fields find multiple applications in industrial product
ion, and correct field strength measurements are an important factor t
o ensure product quality and the occupational safety of the production
staff. In addition, calibrated field strength meters are required for
tests proving the ''electromagnetic compatibility'' of the final prod
ucts. methods and requirements are discussed, how calibration fields c
an be established, which are traceable to national standards. Two diff
erent new constructions of field strength measurement systems useable
as transfer instruments and their technical data are presented.
