More Information: |
The I/A Series Model RTT25 Multivariable Temperature transmitter is
available for single measurements, including seven different RTDs (2, 3
or 4 wire), eleven different thermocouples, millivolts, milliamps and
ohms. Additional sensor flexibility is provided with a 2 to 22 point
custom curve capability and the ability to have the output linear with
temperature or humidity. The transmitter is also available with dual
sensor measurements, providing the capability for "averaging, difference
or redundant" measurements. In addition, the multiple measurement
features combined with the FOUNDATION Fieldbus digital output, one
transmitter can be used for two "individual" process measurements, which
can reduce the number of transmitters required by 50%. The single or dual
input transmitter also accepts mA signals. This allows the conversion of
analog 4 to 20 mA signals to the Fieldbus segment, which can be of
tremendous benefit by integrating legacy devices not available with
FOUNDATION Fieldbus protocol. A wide range of sensors and thermowells,
for remote or integral mounting, are available to meet the needs of all
FOUNDATION Fieldbus installations. Foxboro, a world class supplier to
the process control industry, has provided thousands of users the
benefits of digital "Fieldbus" technologies in field devices and our I/A
Series Control Systems for over a decade. Refer to:
