Product Description

transducer for air velocity, output 4 mA to 20 mA, probe length 145 mm
construction type TC: probe is connected to the electronics via cable

general information:

The transducers of the series HD29... are used for the control of air velocity in the air conditioning and ventilation (HVAC / BEMS) in the pharmaceutical institutions, museums, 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 accurate electronics guarantee precise and reliable measurements.

The sensor for the measurement of air velocity is a thin film, the probe sheath consists of AISI304, the filter for relative humidity consists of 20 µm wire mesh, materials that allow the use even in hostile areas. There are two possible ways of installation: in the TO version, the horizontal probe is connected directly to the electronics enclosure while in the TC version the probe is connected to the electronics via a cable.
