Information:
If the medium reaches the antenna, buildup can form on it and cause
faulty measurements later on.
The emitted radar impulses of VEGAPULS 66 are electromagnetic
waves. The polarisation plane is the direction of the electrical share.
Their position is marked on the instrument.

Make sure that all parts of the instrument coming in direct contact
with the process, especially the sensor element, process seal and
process fitting, are suitable for the existing process conditions, such
as process pressure, process temperature as well as the chemical
properties of the medium.
You can find the specifications in chapter "
Technical data
" and on the
