Abstract

FIELD: physical instruments, in particular, detectors of moisture, porosity, pollution and so on, medical devices which read vapors from skin, identification of securities which are supplied with signs which are made from current-conducting ink or paint. SUBSTANCE: device has dielectric substrate which is covered with electrodes, electronic circuit and indicator. electrodes are designed as two current conductors which are spaced by constant distance and are located on one side of double-side printed circuit which another side contains electronic circuit which has amplitude with indicator, comparator which has setting resistor and is connected to current conductors. EFFECT: increased range, increased precision.

Предлагаемый датчик относится к приборам для исследования физических свойств веществ и может быть использован как датчик влажности, пористости, загрязнений и т.д. Датчик может найти применение в медицине для регистрации испарений с кожного покрова. Кроме того, он может быть применен для идентификации выполненных токопроводящими чернилами или краской маркировочных знаков ценных бумаг. Сущность изобретения заключается в том, что в датчике, представляющем собой диэлектрическую подложку с нанесенными электропроводниками, электронную схему и индикатор, электропроводники выполнены в виде двух протяженных эквидистантно расположенных токопроводников на одной стороне двухсторонней печатной платы, на другой стороне которой с использованием печатного монтажа выполнена электронная схема, состоящая из усилителя с индикатором, и подключенного к токопроводникам компаратора с задающим сопротивлением. Предлагаемый датчик обеспечивает широкий диапазон измерения электропроводности с повышенной точностью.The proposed sensor relates to devices for studying the physical properties of substances and can be used as a sensor of humidity, porosity, pollution, etc. The sensor can be used in medicine to detect fumes from the skin. In addition, it can be used to identify securities marked with conductive ink or paint. The essence of the invention lies in the fact that in the sensor, which is a dielectric substrate with deposited electrical conductors, the electronic circuit and indicator, the electrical conductors are made in the form of two long equidistant conductors located on one side of a double-sided printed circuit board, on the other side of which an electronic circuit is made using printed wiring , consisting of an amplifier with an indicator, and a comparator with a reference resistance connected to the conductors. The proposed sensor provides a wide range of conductivity measurements with increased accuracy.
