 TP303
Profibus PA Position Transmitter
The
TP303 is from the first generation of Profibus-PA devices. It is a transmitter
for position measurements. It can measure displacement or movement of
rotary or linear type. The digital technology and communication provide
an easy interface between the field and control room and several interesting
features that considerably reduce the installation, operation and maintenance
costs.
The
TP303 is versatile and reliable, and has very high accuracy. It may
be used for control valve stem position measurement or in any other
position sensing application such as louvers, dampers, crushers, etc.
Since the TP303 uses a non-contact magnetic coupling for position sensing,
it is less sensitive to vibration than other solutions, resulting in
longer operational life. The TP303 is part of Smar's complete 303 line
of Profibus-PA devices.
