f the medium reaches the antenna, buildup can form on it and cause
faulty measurements later on.
T he emitted radar pulses of VEGAPULS 67 are electromagnetic
waves. They thus have electrical and magnetical components that are
perpendicular to each other. The polariation plane is defined by the
direction of the electrical component. With radar sensors, the
polarisation can be used to considerably reduce the effect of false
echoes by turning the instrument in the connection flange or mounting
boss. The position of the polarisation plane is marked on the
instrument.
