Perfect performance – our special solutions for extreme humidity
Where other humidity sensors have long since reached their limits, the KFTF-35 and -45 duct humidity sensors and the AFTF-35 and -45 on-wall humidity sensors from S+S Regeltechnik prove their strengths. Thanks to innovative technology and robust construction, they deliver reliable measurements even in areas with up to 99% relative humidity – stable and precise over the long term.
What makes S+S Regeltechnik's high-humidity sensors so special?
AFTF-35 / KFTF-35:
-
Long-term stable, digital sensor with separate temperature measuring element.
-
Overtemperature: prevents or hinders condensation on the humidity sensor.
AFTF-45 / KFTF-45:
-
High protection class: (IP65) – especially for harsh environments.
AFTF-35 / KFTF-35 /AFTF-45 / KFTF-45:
-
More than just humidity and temperature: absolute humidity, mixing ratio, dew point, and wet bulb temperature are calculated internally and can be retrieved.
-
Flexible signal processing: 0–10 V or 4…20 mA standard signal.
-
Robust housing made of impact-resistant plastic with quick-release screws.
-
Versions with or without display – the right solution for every application.
-
Factory calibrated, fine adjustment by qualified personnel possible at any time.
Where are the humidity sensors for high humidity from S+S Regeltechnik used?
As a duct sensor in refrigeration technology
Ventilation and cooling systems often have extremely high humidity levels. The KFTF-35 sensor impresses with its condensation-proof design: even at 95–99% relative humidity, it delivers reliable values and enables precise control. The flange for mounting directly on the duct is included in the scope of delivery.
Als Aufputzgerät in Gewächshäusern
As a on-wall device in greenhouses In mushroom cultivation facilities, consistently high humidity is crucial for optimal growth. Mounted as a surface-mounted device, the AFTF-45 – with IP65-protected housing and sensor technology – ensures reliable measurement of temperature and humidity, while also allowing important parameters such as dew point or absolute humidity to be derived directly (configurable via DIP switch).
Other typical areas of application include testing facilities, wet rooms in sanitary areas, and clean rooms – in other words, anywhere where conventional sensors reach their limits due to condensation.
