Иаобретеии. -гмоситс к устройствам дп измерени и копчроп температуры, которые могут быть использованы дп измерени температуры в буровых скважинах.Ioboboreeii. - gomit to dp measurement devices and temperature drift, which can be used dp temperature measurement in boreholes.
Известны эпектрические термометры дл 5 измерени температуры рудного тепа l|, 2, содержащие измеритепьную мостовую схему с рабочим и компенсационным термистерами источник питани , измеритепьный бпок, полупроводниковые эпементы и репе.ЮElectro-thermometers are known for measuring ore heat temperature l |, 2, containing a measuring bridge circuit with a working and compensating thermisters power supply, measure the power supply, semiconductor epements, and turn signals.
Их испопьзование не эффективно из-за нелинейности и нестабильности характеристик во времени, ппохой повтор емости резупьтатов измерений и необходимости индивидуагЕЬной градуировки.15Their use is not effective due to the nonlinearity and instability of the characteristics over time, due to the repetition of measurement results and the need for individual calibration 15.
Известен также эпектрический термометр дп измерени температуры рудного тепа 3 содержащий измерительную мостовую схему с рабочим и компенсационным термисторами, источник питани , измеритепьный бпок со 20 стрепочным индикатором и коммутатор.Also known is an electric thermometer dp for measuring ore heat temperature 3 containing a measuring bridge circuit with operating and compensating thermistors, a power source, measure the bpoc with a 20 streamer indicator, and a switch.
С цепью повышени точности измерени путем пиквидации пол ризации термисторов, рабошй и компенсационный термисторы включены в ппечи мостовой схемы, каждый 25With a circuit for improving measurement accuracy by picking up the polarization of thermistors, the working and compensating thermistors are included in the bridge circuit presses, each 25
