Humidity Sensors

High chemical resistance, very low drift a wide temperature range and condensation-resistance are just a few of the many characteristics of our humidity sensors. IST humidity sensors feature many different benefits, from a high humidity stability, over suitablility for extreme environments and to dew point measurement. 

Humidity Modules

Humidity Modules

Techanically robust and with a chemical and condensed waterproof sensing area, IST AG's digital  HYT humidity modules offer a wide application window and an optimal price-performance ratio. Precisely calibrated, the HYT modules deliver an outstanding accuracy and excellent long-term stability even at high humidity - ideal for sophisticated mass applications, industrial handheld devices and precise humidity transmitters.

Capacitive RH sensors

 

Capacitive RH sensors consist of a ceramic substrate on which a thin film of polymer is deposited between two conductive electrodes. The sensing surface is coated with a microporous metal electrode, allowing the polymer to absorb moisture while protecting it from contamination and exposure to condensation. As the polymer absorbs water, the dielectric constant changes incrementally and is nearly directly proportional to the relative humidity of the surrounding environment. Thus, by monitoring the change in capacitance, relative humidity can be derived.
