METHODS AND PRINCIPLES OF CONSTRUCTION OF MEASURING INSTRUMENTS HUMIDITY OF THE ENVIRONMENT

Abstract

Humidity control is necessary in many companies. The method of measuring the humidity of the resistive sensor mainly depends on the moisture content in the non-metallic conductor, due to which the resistance of the conductor changes. The subject of the article is the basic methods and principles of constructing instruments for measuring the humidity of the environment and their control. The purpose of the article is to substantiate the expediency of using moisture measuring instruments when operating equipment at various enterprises and in various industries. The task that is being solved is the substantiation of the methods and principles of measuring the humidity of the environment using pink methods and methods, which of the methods is the most common and which are the main disadvantages in hygrometry. Conclusions: of all the proposed methods, the most common methods for measuring humidity are a condensation hygrometer, used in the gas and oil industry, capacitive and resistive methods that measure moisture in liquids and bulk materials, the coulometric method allows you to measure moisture at low values, as well as psychrometers, which are the most common due to their stability at a low cost.
