Ex Differential Pressure Transmitters

Models: 4-20mA & HART, Foundation Fieldbus, Profibus PA

Note:  The operating protocols of these transmitters are easily changed by either replacing the internal electronic board or downloading the replacement firmware.

Thus, a HART
® / 4 - 20mA transmitter can be changed into a FOUNDATION fieldbus  or  PROFIBUS PA device simply by replacing the internal card, and vice-versa.

A FOUNDATION fieldbus device can be changed into a PROFIBUS PA device and vice-versa, by simply downloading a new firmware.

LD301D 4-20mA  & Hart

LD301 (HART® protocol) can be configured by:

Smar CONF401 for Windows and UNIX;
Smar DDCON100 for Windows and UNIX;
Smar HPC301 and HPC401 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 and HHT375, PRM Device Viewer.

For LD301 management and diagnostics, Asset View ensures continuous information monitoring.

* Requires HPI311.

 


LD302D

 

Foundation Fieldbus

 

LD302 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 LD302 devices. DD (Device Description) and CF (Capability File) files can be downloaded at either the Smar or Fieldbus Foundation website.

LD302 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 fieldbus result in a safer plant with longer availability.

 

LD303D Profibus PA LD303 (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 PROFIBUS System using the GSD file.

PROFIBUS PA also has quality and diagnostic information, improving plant management and maintenance.
