The LD290 - Pressure Transmitter 4-20 mA Microprocessor Based is the economical alternative in routine gauge 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.
