TT301
 Smart
Temperature Transmitter 4-20 mA + HART
The
Smar TT301 is a powerful and extremely versatile
programmable temperature transmitter, which
can be used with practically all relevant temperature
sensors as well as with load cells, resistance
position indicators, etc. The TT301 transmitter
is suitable for direct field installation, being
weather and explosion proof as well as intrisically
safe.
As
the same unit can be used for different measuring
ranges and many types of sensors, the plant
can be standardized using the TT301 in measurements
where different types of conventional (analog)
transmitters were previously necessary. This
drastically reduces calibration and maintenance
time, spare part requirements and trainning.
It also allows the TT301 to be purchased before
measurement and control parameters are known.
