The ultrasonic signal is sent directly between the transducers. The advantage gained sending
signals from point to point is an extremely good signal strength.

PROFIBUS communication
PROFIBUS (Process Field Bus) is an open communication system for automation engineering
which is being used in its thousands all over the world and which is specified in the European
standard EN 50170.
PROFIBUS PA
PROFIBUS PA (PA = Process Automation) is a variant of PROFIBUS DP which is used widely in
production engineering. It has special a transmission technique and therefore satisfies the
requirements of process automation/materials processing. This transmission technique is
defined in the international standard IEC 61158-2. The low transmission speed reduces the
power loss and therefore enables an intrinsically safe technology for use in areas where there is
a high explosion risk. Line, star and tree structures are possible as well as combinations of these.
All kinds of field devices such as transducers, actuators, analyzers, etc. can be connected to the
PROFIBUS PA. The essential advantage in addition to the saving of installation costs is the
possibility of a more detailed diagnosis with an increase in the availability of the plant
components. Furthermore, the automatic updating of plant documentation and plant
optimization during ongoing operation is supported.
