Hygrostat
The hygrostat (from Greek ὑγρός hygros 'moist' and στατός statos 'standing') is used to regulate the relative humidity in rooms. The sensor's moisture measuring element consists of plastic fabric tapes with hygroscopic properties. The absorption of water changes the structure of the fibers, which results in a measurable change in length. The length of the fibers is therefore a measure of the relative humidity. The effect, which mainly acts in the longitudinal direction, is fed to a switch with a very small switching path via a fork system. By setting the setpoint button, the fork system is intervened so that a switch is operated when the set humidity is reached. The perforated sensor tube protects the fibers. The hygrostat is used to control air humidifiers and dehumidifiers z. B. in food cold rooms, greenhouses, rooms in the textile and printing industry or in hospitals.
