These hygrometers are simple spiral springs made of a metal spring strip, which is covered with a hygroscopic gel layer on one side. They work similarly to the bi-metal springs, i.e. the hygroscopic side expands due to water absorption and a signal is transmitted proportional to the relative humidity. There are now hygrometer springs that do not even yield at a permanent exposure of 100% RH. These metal springs and their absorptive layer have been specially adjusted to reach a low hygroscopic hysteresis and the same accuracy as the [[Hygrometric Measuring Methods|hair hygrometer]]. | These hygrometers are simple spiral springs made of a metal spring strip, which is covered with a hygroscopic gel layer on one side.
