This stand is composed of the following elements: a static frequency converter that supplies a three-phase asynchronous motor, a tachymeter for rpm measurement a central unit and monitor for control and monitoring, and a single-phase synchronous generator for loading the three-phase asynchronous motor.
A hygrometer is an instrument used to measure relative humidity. It is also called a psychrometer. In order to determine relative humidity, the hygrometer makes use of wet and dry bulb thermometers. The difference in temperatures between the two measurements are an indicator of evaporation, therefore also relative humidity.
