(54) ОПТОЭЛЕКТРОННЫЙ ИЗМЕРИТЕЛЬ ВЛАЖНОСТИ(54) OPTOELECTRONIC MOISTURE METER
1one
Изобретение относитс к влагометрии и может быть использовано дл измерени влажности воздуха в широких диапазонах.The invention relates to moisture measurement and can be used to measure air humidity over a wide range.
Известен измеритель влажности, содержащий конденсационное зеркало с термодатчиком , хладогенератор, усилитель и регистратор 1.Known moisture meter containing condensation mirror with a temperature sensor, refrigeration generator, amplifier and recorder 1.
Наиболее близким по техническому решению к предлагаемому вл етс оптоэлектронный измеритель влажности, содержаший конденсационную камеру с термодатчиком и хладогенератором, св занным с синхронизированным блоком питани , функциональный усилитель, подключенный к-термодатчику , источник излучени , оптически св занный через контролируе.мую среду с фотопреобразователем, и реегистратор 2.The closest technical solution to the present invention is an optoelectronic moisture meter containing a condensation chamber with a thermal sensor and a cold generator connected to a synchronized power supply unit, a functional amplifier connected to a thermal sensor, an optical source optically coupled through a controlled medium to a photoconverter, and registrar 2.
Недостатком данного устройства вл етс больша погрешность измерений, св занна с наличием градиента температуры конденсационной плошадки (зеркала), охлаждаемой до точки росы, и исследуемого газа и неточностью фиксации момента по влени росы из-за того, что капли росы должны возрасти до определенной величины , чтобы обеспечить прерывание светового потока.The disadvantage of this device is the large measurement error associated with the presence of the temperature gradient of the condensation plate (mirror) cooled to the dew point, and the gas under investigation and the inaccuracy of fixing the moment of dew appearance due to the fact that the dew drops must increase to a certain value, to ensure the interruption of the light flux.
Цель изобретени - повышение точности .The purpose of the invention is to improve accuracy.
Поставленна цель достигаетс тем, что в устройство дополнительно введены два ключа и два запоминающих устройства. причем выход функционального усилител св зан с. двум ключами, выход каждого из которых св зан со своим запоминаюш1 М устройством, подключенным к регистратору , при этом вход одного из ключей св зан с фотопреобразователем, а вход другого - с синхронизированным блоком питани .The goal is achieved by the addition of two keys and two storage devices to the device. wherein the output of the functional amplifier is coupled to. two keys, the output of each of which is associated with its memory device connected to the recorder, the input of one of the keys associated with the photovoltage transducer, and the input of the other with a synchronized power supply unit.
На чертеже приведена структурна схема устройства.The drawing shows a block diagram of the device.
Устройство содержит кнопку 1 запуска, источник 2 ионизирующего излучени , конденсационную камеру 3, термоприемный элемент 4, полупроводниковый хладогенератор 5, фотоприемное устройство 6, усилитель 7, блок 8 нелинейности, ключевые схе-. мы 9 и 10, элементы 11 и 12 пам ти и регистратор с блоком 13 делени .The device contains a start button 1, an ionizing radiation source 2, a condensation chamber 3, a thermal receiving element 4, a semiconductor refrigeration generator 5, a photoreceiver 6, an amplifier 7, a nonlinearity unit 8, key circuits. we are 9 and 10, elements 11 and 12 of memory, and a recorder with a block of 13 divisions.
Устройство . работает следующим образом .Device works as follows.
Анализируема воздушна масса подаетс в конденсационную камеру 3, гдеThe air mass to be analyzed is fed to the condensation chamber 3, where
