Characteristics The principle of the measurement method makes it possible to avoid
influences from primary or secondary polarization effects, which
ensures a high degree of measuring accuracy.
A modern epoxy sealing technique reduces the chances of breakage of
the sensor in the rough industrial environment.
1.3 Recommended fields of application
