LD293
Profibus Pressure Transmitter
The
LD293 is from the first generation of PROFIBUS-PA devices. It is an
economical alternative gauge pressure transmitter. It is based on a
field-proven capacitive sensor that provides reliable operation and
high performance.
This
lightweight design eliminates the need of mounting brackets and transmitter
support in many applications. Its microprocessor-based electronics allow
for total interchangeability with SMAR capacitive sensors, correcting
automatically sensor characteristic changes caused by temperature fluctuation.
The
digital technology used in the LD293 enables the choice of several types
of transfer functions, an easy interface between the field, the control
room and several interesting features that considerably reduce the installation,
operation and maintenance costs.
