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.
