TT301 HART Intelligent Temperature Transmitter
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.
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*;
Also other manufacturers’ configuration tools based on DD (Device Description) or DTM (Device Type Manager), such as AMSTM, FieldCareTM, PACTwareTM, HHT275, HHT375 and PRM Device Viewer. For management and diagnostics, AssetView ensures continuous information monitoring.
*Requires HI311 (HART Serial Interface).
DT301 Hart Intelligent Density Transmitter
The DT301 4 to 20 mA + Hart Density Transmitter is an instrument developed for the continuous, online measurement of liquid concentration and density, directly in the industrial process.
Technology – Capacitive type differential pressure transmitter coupled to a pair of pressure repeaters immersed in the process.
A temperature sensor located between the two pressure repeaters is used to compensate the temperature variations in the process fluid. A dedicated software, by means of an algorithm, calculates the fluid density. Depending on the industrial process, density may be expressed in Brix degree, Gay-Lussac degree, Baumé degree, Plato degree, concentration, etc.
Designed for process control applications, these 2-wire transmitters generate a 4-20 mA signal proportional to the density. Digital communication for remote calibration and monitoring is also provided.
SR301 Remote Seal Transmitter
The SR301 is a Remote Seal that allows the pressure transmitter to make measures in situations where the immediate contact of the transmitter diaphragm with the process fluid it is not allowed.
The remote seal is made up by one connection with the diaphragm and one capillary connection with filling fluid. The filling fluid transfers the pressure measured in the process fluid to the transmitter sensor. The capillary connection links the seal diaphragm to the transmitter.
The remote seals available in the SR301 series are: Flanged “T” Type (SR301T), Threaded (SR301R), Pancake (SR301P) both models having an optional flush connection, Sanitary (SR301S), Flanged with Extension (SR301E) and Pancake with Extension (SR301Q).
