 LD291
Smart Pressure Transmitter 4 to 20 mA
+ HART
The
LD29X series is the economical alternative in routine gage pressure
measurement. The lightweight design eliminates the need for mounting
brackets and transmitter supports in many applications.
The model LD291 offers digital HART based communication simplifying calibration and providing remote diagnostics.
Its microprocessor-based electronics allow for total interchangeability
with SMAR capacitive sensor. It automatically corrects sensor characteristic
changes caused by temperature fluctuations.
