Dual Absolute Humidity & Temperature Transmitters

Dual Absolute Humidity & Temperature Transmitters

Model Number
HD3817T / HD38V17T


Standard Lead Time
3 weeks

Absolute humidity is the ratio between the mass of water vapor per volume of air, and is expressed in g/m3. The transmitters of the HD3817T are used to monitor and control humidity during a drying process. When drying through heating or hot air flow, the air absolute humidity increase is directly proportional to the quantity of water lost. A control system measuring absolute humidity, can maintain a humidity level by injecting vapor or spray into the process environment.

Common applications are in the following industries:

Chemical, textile, food, production and storage of paper, and drying of lumber.

These sensors are immune to most chemical exposures.

The maximum working temperature is 200 °C which makes these instruments particularly suited to heavy industrial applications where the traditional capacitive sensor cannot be used.
