Teknik Bilgi

The HD3817T… and HD38V17T… are double absolute humidity and temperature active transmitters with 4…20mA current or 0…10Vdc voltage outputs, respectively.

Absolute humidity is the ratio between the mass of water vapour and the measured volume of air, and is expressed in g/m³.

The transmitters of the HD3817T… family may be used in materials humidity control during a drying process. When the materials are dried through heating or a hot air flow, the air absolute humidity increase is directly proportional to the quantity of water lost by the materials. A control system measuring absolute humidity, can maintain a certain humidity level by injecting vapour or water spray in the environment, if needed.

Generally, these transmitters are employed in the chemical, textile, food industry, in the production and storage of paper, in the drying of wood, even with high temperatures and wide humidity excursions.

The type of sensor used is immune to most physical and chemical contaminants. The maximum working temperature is 200°C: This makes these instruments particularly suitable to heavy industrial applications where the traditional capacitive sensor cannot be used.
