The TT300
Series is a transmitter mainly intended for measurement of
temperature using RTDs or thermocouples. However, it can also accept
other sensors with resistance or mV output such as: pyrometers, load
cells, resistance position indicators, etc. The TT300 Series
accepts up to two sensors and may operate in one of the modes:
• Single channel with single sensor measurement;
• Dual channel with dual sensor measurement;
• Single channel with dual sensor differential measurement;
• Single channel with dual sensor back-up measurement.
The TT300
Series is a powerful and extremely versatile smart temperature
transmitter. The digital technology used in the TT300 Series
enables a single device to accept several types of sensors, wide
ranges, single or multiple-ended measurement and an easy interface
between the field and the control room. It also includes several
interesting features that reduce considerably the installation,
operation and maintenance costs. The transmitter accepts two channels,
i.e., two measurements. This reduces the cost per channel.

TT301 |
4-20mA & Hart |
TT301 (HART® protocol) can be configured by:
Smar CONF401 for Windows and UNIX;
Smar DDCON100 for Windows and UNIX;
Smar HPC301 for several models of Palms*;
Other manufacturers' configuration tools based on DD (Device Description)
or DTM (Device Type Manager), such as AMS, FieldCare, PACTware,
HHT275, HHT375 and PRM Device Viewer.
For management and diagnostics, AssetView ensures continuous information
monitoring. |

TT302 |
Foundation Fieldbus |
TT302 utilizes the FOUNDATION fieldbus H1 protocol, an open technology
that allows any H1 enabled configuration tool to configure this device.
Syscon302 (System Configuration Tool) is a software tool used to configure,
maintain and operate the field devices. Syscon offers efficient and
friendly interaction with the user, using Windows NT version 4.0 or
later, Windows 2000 and Windows XP.
Configuration tools such as AMS, FieldCare and HHT375 can configure
TT302 devices. DD (Device Description) and CF (Capability File) files can
be downloaded at either
the
Smar or
Fieldbus Foundation
website.
TT302 supports complex strategies configuration due to the high capacity
and variety of dynamic instantiable function blocks. |

|
TT303 |
Profibus PA |
TT303 (PROFIBUS PA protocol) can be configured using Simatic PDM and by
the FDT (Field Device Tool) and DTM (Device Type Manager) concept tools,
such as FieldCare and PACTware.
It can also be integrated by any PROFI-BUS System using the GSD file.
PROFIBUS PA also has quality and diagnostic information, improving plant
management and maintenance.
