Изобретение относитс к теплоизмерительным приборам.This invention relates to heat meters.
Известные устройства дл контрол температуры , в которых приемники тепловой радиации включены в измерительный мост, не обеспечивают достаточной точности измерений.The known temperature monitoring devices in which the thermal radiation receivers are included in the measuring bridge do not provide sufficient measurement accuracy.
Дл повышени точности измерений в предлагаемом устройстве в одну пару противоположных плечей мостовой схемы включены приемники тепловой радиации, выполненные в виде оптроиов, а в другую - фоторезисторы .To improve the measurement accuracy in the proposed device, one pair of opposite shoulders of the bridge circuit includes thermal radiation detectors made in the form of optroi, and the other photoresistors.
На чертеже изображена электрическа схема предлагаемого устройства.The drawing shows the electrical circuit of the proposed device.
В противоположные плечи моста включены фоторезисторы 1, а в два остальных плеча - оптроны 2, используемые в качестве приемников тепловой радиации.Photoresistors 1 are included in the opposite shoulders of the bridge, and optocouplers 2, used as receivers of thermal radiation, are included in the other two arms.
В диагональ моста включен терморезистор 3, а параллельно ему - сигнально-регистрирующее устройство 4.A thermistor 3 is connected to the bridge diagonal, and parallel to it is a signal-recording device 4.
Источником питани служит, например, элемент 5.The power source is, for example, element 5.
