The SMAR LD1.0 capacitive economical pressure transmitter was designed for measuring gauge and absolute pressure of liquids, gases and vapors on many industrial applications. This low cost transmitter is the only one in the category that uses capacitive cell technology as pressure sensor to read pressure in an entirely digital way. As a high reliability and robustness sensor, it is employed in more than 80 percent of high performance pressure measuring all over the world, for its excellent accuracy, repeatability and linearity. The LD1.0 Pressure Transmitter production and mounting features provide resistance to vibration, shock, large temperature variations, immunity to electromagnetic interference and other typical extreme environment conditions of industrial applications.
The DT300 “Touché” is available in two models:

•DT300I (Industrial Model) for general purpose;
•DT300S (Sanitary Model) for food and other applications where sanitary connections are required.
Both models have two mounting types: top mounting (straight type) and side mounting (curved type).
Installation may be done either in open or pressurized tanks, or directly in pipes since the DT300 is suitable for dynamic and static fluids.

The Sanitary model that meet 3-A Certification (Authorization N° 1399) uses a Tri-Clamp connection to allow a quick and easy connection and disconnection from the process. The wetted surface finish is polished and then is free of crevices where food or bacteria can be collected. 3A is the most widely accepted sanitary standard in the food, drug and beverage industry.
DT301 (HART® protocol) can be configured by:
•CONF401 for Windows and UNIX;
•DDCON100 for Windows and UNIX;
•HPC301 for several models of Palms*;
•Other manufacturers’ configuration tools based on DD (Device Description) or DTM (Device Type Manager), such as AMSTM, FieldCareTM, PACTwareTM, HHT275 and HHT375, PRM Device Viewer.
For DT301 management and diagnostics, Asset View ensures continuous information monitoring.
*Requires the HPI311 or HPI321 interface.
DT302 utilizes the Foundation fieldbusTM 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 AMSTM and HHT375 can configure DT302 devices. DD (Device Description) and CF (Capability File) files can be downloaded at either the Smar or Fieldbus Foundation website.
DT302 supports complex strategies configurations due to the high capacity and variety of dynamic instantiable function blocks.
Seventeen different types of function blocks are supported, and up to 20 function blocks can be running simultaneously. Maintenance procedures with Asset View diagnostics and status information from Foundation fieldbusTM result in a safer plant with longer availability.
