DPT 820
The DPT-820 measures moisture content in gasses in the range -110℃ dp to +20℃ dp and provide a 4-20mA output linear to the measurement units chosen.The factory default is 4mA=-110 ℃and 20mA= +20℃.The defaults can bu modified in value and units (available units:℃ dewpoint, ppmV,RH%).The DPT-820 is a Loop-Powered Blind (three wire)Transmitter;it has display self and can consuming power in the range of 4mA to 20mA
