HD29 - Transmitters series for direct (In-situ) measurement in ducts. Airspeed and/or Temperature an/or Humidity. Several lengths, analogue outputs 4-20mA or 0-10VDC.
The family of transmitters series HD2903t ... are employed in the control of air speed in the air conditioning and ventilation (HVAC / BEMS) in the pharmaceutical, museum, clean rooms, ventilation ducts, industrial sectors and households, crowded places, cafeterias, auditoriums, gymnasiums or on farms with large numbers of animals. The sensors in combination with an accurate electronics guarantee precise and reliable measurements in the time.
The sensor for the air speed is thin film, the probe sheath is AISI304, the filter relative humidity of 20μ wire mesh, materials that allow the use in hostile areas.
There are two possible installations: in the TO version, the horizontal probe is joined to the electronics enclosure while in the TC version the probe is conconnected to the electronics through a cable.
In the TO version, the duct probe is fixed to the electronics enclosure and it is available in three different lengths. To fix the probe to the duct, you can use, for example, the HD9008.31 flange, a 3/8” universal biconical connection or a PG16
metal cable gland (∅10…14mm).
In the TC version, the probe together with the sensors is equipped with a cable which can be 2, 5 or 10 meters long. The probes are available in three different lengths.
Possibilities of the several models:
- Airspeed measurement with the HD29x3Txxxx serie - analog output 4-20mA or 0-10VDC
- Airspeed and Temperature measurement with the HD29x37xxxxx serie - analog outputs 4-20mA or 0-10VDC
- Airspeed, Humidity and Temperature measurement with the HD29x371xxxxx serie - analog outputs 4-20mA or 0-10VDC
