Sensors for high humidity AFTF-35 and KFTF-35

The KFTF 35 duct humidity and temperature sensors were developed for applications involving high humidity, condensation, and significant temperature fluctuations. Thanks to their condensation-protected design, they deliver precise and long-term stable measurements even at relative humidity levels of 95 to 99%. In addition to humidity and temperature, other calculated parameters such as dew point or absolute humidity are available. With 0…10 V or 4…20 mA outputs, a rugged housing, and variants with or without a display, these sensors are ideal for demanding applications in building automation and industry.
