COSA HDT Loop-Powered Dewpoint Transmitter with HART®

Cosa's model HDT is a HART-compliant hybrid dewpoint transmitter with both loop-powered analog and digital outputs. Multiple units can operate on the same loop cable to function as a multichannel instrument — with each HDT drawing only 4mA independent of the measured dewpoint. HDT provides a factory programmable dewpoint alarm signal through the digital output pin. Relays or external devices can be operated through the analog or digital loops.
