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.

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.
