Specification

The HD29 series of transmitters… are used for controlling air speed for conditioning and ventilation applications ( HVAC/ BEMS) in the following sectors: pharmacy, museums, clean rooms, ventilation ducts, crowded places, canteens, auditoria, gyms or high-density farms, as well as industrial and civil sectors.
The sensors in combination with an accurate electronics guarantee precise and reliable measurements in the course of time.
The thin film sensor for air speed, the AISI304 probe sheath, the 20¼ metal grid filter for Relative Humidity enable their usage even for hostile applications.
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 connected 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 fl ange, 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.
