Изобретение относитс к области контактной термометрии.This invention relates to the field of contact thermometry.
Известны способы измерени температуры электрическими термометрами сопротивлени .Methods are known for measuring temperature with electrical resistance thermometers.
При Измерени х этими опособа-ми дл повышени чувствительности и точности принимаютс специальные меры по отграничению измерительного тока, протекаюн;его через термометр.When measuring with these methods, special measures are taken to increase the sensitivity of the measuring current, flow through the thermometer to increase sensitivity and accuracy.
Однако известный способ не обеспечивает требуемой чувствительности измерительной схемы в результате самонагрева термометра сопротивлени измерительным током.However, the known method does not provide the required sensitivity of the measuring circuit as a result of self-heating of the resistance thermometer by the measuring current.
Дл использовани термометра в широком диапазоне измер емых температур по предлагаемому способу поддерживают неизменной разлость температур между термометром сопротивлеПи и окружающей с,редой путем регулировани мошадости, подводимой к термометру Сопротивлени .To use the thermometer in a wide range of measured temperatures, the proposed method maintains a constant temperature difference between the resistance thermometer and the surrounding thermometer by adjusting the power supplied to the resistance thermometer.
Учитыва , что относительна погрешность измерНтельного устройства св зана с чувствительностью обратно пропорциональной зависимостью , следует, что предложенный способ не только увеличивает чувствительпость схемы ИЗмерени , но и Соответственно уменьшает погрешность измерени .Taking into account that the relative error of the measuring device is related to the sensitivity inversely proportional dependence, it follows that the proposed method not only increases the sensitivity of the MEASUREMENT circuit, but also Respectively reduces the measurement error.
