LD292
Foundation Fieldbus Pressure Transmitter
LD292 - Foundation Fieldbus Pressure Transmitter offers digital Foundation Fieldbus based communication simplifying
calibration and providing remote diagnostics. Its microprocessor-based
electronics allow for total interchangeability with SMAR capacitive
sensors, correcting automatically sensor characteristic changes caused
by temperature fluctuation.
LD292 - Foundation Fieldbus Pressure Transmitter utilizes the Foundation™ fieldbus H1 protocol, an
open technology that allows any H1 enabled configuration
tool to configure this device.
Syscon (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 LD292 devices. DD
(Device Description) and CF (Capability File) files
can be downloaded at either the SMAR or Fieldbus
Foundation™ website.
Parameterization and Diagnostics
LD292 - Foundation Fieldbus Pressure Transmitter 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 AssetView diagnostics and
status information from Foundation™ fieldbus result in a safe
plant with higher availability.

Update for HART and PROFIBUS PA |
These protocols are easily changed by either replacing the
internal electronic board or downloading the firmware. A
FOUNDATION fieldbus transmitter can be changed into a HART device 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. |
