ATT 2250

ATT 2250 Smart Temperature Transmitter

ATT 2250 Smart Temperature Transmitter

The ATT 2250 series head mount type transmitter is the HART communications protocol. The standard HART universal and common usage commands are implemented, with other device-specific commands that enable access to the enhanced performance parameters of the ATT 2250 series.
