DAI SERIES PRESSURE TRANSMITTER
with Integrated Amplifier - mA or V output
The DAI Series offers – in addition to maximum
reliability – improved user friendliness in the form
of an Auto-Zero Function for local or remote
configuration. These models offer mA and V
output signals for further processing. The popular
and most commonly used 2- wire and 4...20mA
configuration provide unequalled interference in
critical environments.
