Universal design with changeover contact, suitable for dryers and humidifiers
The physical measuring principle of this humidity controller is based on the characteristics of the hygroscopic polyamide tape which is tensioned by a spring.
The water content in this plastic tape is in balance with the relative humidity (% RH) of the surrounding atmosphere and the length of the tape changes reversibly depending on the actual air humidity (% RH) value in the air.
Adjusting the switching point is by simply turning the knob and may be directly used for controlling electric loads.
Unlike other electronic devices the hygrostat requires no power supply.
Areas of application include:
Air dryers, air dehumidifiers, air humidifiers, air conditioning technology, climatic and ventilation systems
