HD49 Series – Passive Temperature-Humidity Transmitters
Brand: Delta OHM S.R.L.HD49 transmitters are designed for temperature and humidity control in conditioning and ventilation applications (HVAC/BEMS).
The models of the HD49 series are passive transmitters and thus suitable to be inserted in a 4 to 20mA current loop.
Available models:
- horizontal probe for duct mounting (TO),
- vertical probe for wall mounting (TV),
- probe with 2 or 5 m cable (TC),
- fixed contact Pt100 probe for solar panel (TFP)
