DUCT TEMP./HUMI. TRANSMITTER : GDTH-1420
"GDTH" Duct Temperature & Humidity Transmitter is intended for ventilation and Air-Handling units to detect Duct temperature and relative humidity.
Especially, This unit is very suitable for using in pulp / textile / food ware-house , green house , computer room , R & D room , indoor swimming pool , Hosptial etc.
This unit can be used with all system equipments that can receive output signals 4~20mA DC of the detector.
● Relative humidity
Electronic sensing circuit varies signal into 4~20mA DC (Within 0~100% relative humidity)
● Temperature
This transmitter senses temperature by sensing element of Pt1000Ω which varies electrical resistance depending on sensing temperature
