HD49… SERIES-RH & Temperature Passive Transmitters
Humidity, Temperature
Temperature, relative humidity and dew point transmitters with passive 4÷20 mA analogue output.
HD49 transmitters are designed for temperature and humidity control in conditioning and ventilation applications (HVAC/BEMS) in the following sectors: pharmacy, museums, clean rooms, ventilation ducts. Industrial and civil sectors, crowded places, canteens, auditoria, gyms, high-density farms, greenhouses, etc.
The models of the HD49… series are passive transmitters and thus suitable to be inserted in a 4…20mA current loop.
Available models:
- horizontal probe for duct mounting (TO),
- vertical probe for wall mounting (TV),
- probe with 2 or 5m cable (TC),
- fixed contract Pt100 probe for solar panel (TFP)
For the TO and TC versions, two probe temperature ranges are possible: standard -20…+80 °C and extended -40…+150 °C (option E). Temperature range of the thin film1/3 DIN Pt100 probe for solar panel: -40…+85 °C.
HD49 transmitters are also available with LCD display (option L). Electronic working temperature: -20…+60 °C.
