Pressure & Differential Pressure Transmitters with HART Protocol

LD301
Smart Pressure Transmitter Series

LD301 Series is a complete line of level, differential, gage and absolute pressure transmitters. Models include flush diaphragm and sanitary flange for liquid level measurement, Hydrostatic Tank Gauging - HTG (model LD301T) and wetted parts in several materials for suiting process requirements. All models can be supplied with various remote seals. The CONF401 is a configuration interface developed for the LD301.

LD290
Pressure Transmitter 4 to 20 mA Microprocessor Based

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 LD290 is a pure 4-20 mA transmitter.

Besides its analog output, its microprocessor-based electronics allow for total interchangeability with SMAR capacitive sensors. It automatically corrects sensor characteristic changes caused by temperature fluctuations.
