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.
