Description

There are known devices for automatic regulation of air humidity, which contain an electric bridge, in one of which a humidity sensor is included, made of a moisture-sensitive type ;. resistance, two double triodes and a moisture indicator. The bridge is powered by a current transformer from a power transformer through a rectifier and staile. the cathodes of which having been connected by the indicator-assembled bridge; humidity. In the measuring diagonal of the bridge, the potentiomeg is inserted, with the engine attached to one of the grids of the other double Tpiio.i. in the anode circuit, which has a relay with contacts, is found: electrical circuit of the actuator. This embodiment increases the reliability of its operation and provides simultaneous regulation and measurement of humidity. The drawing shows the electrical wiring circuit of the pr i device. The device contains a humidity sensor D, made in 11) mode, which reacts to a change in humidity. Predisc sensor, -1 em a glass plate, on the surface of which impose ;; G-: Gyroscopic coating from a mixture of a cookware and a sep.etovoi soleya a; A: Filtered aluminum wire. To obtain a rurpock ..: the plating of the plate is immersed in a pastern solution n; ... 1 S of salt containing a given concentration of a segnetovoe and sun. .-h-- The extracts in the solution plate are dried and calcined with an--h.hm --- skim current.
