Description
(54) СПОСОБ ТЕРМОАНЕМОМЕТРИЧЕСКИХ ИЗМЕРЕНИЙ(54) METHOD FOR THERMO-ANEMOMETRIC MEASUREMENTS
При наличии предварительной силы нат жени нити изменение ее размеров по дпине обуславливает дополнительное изменение, электрического сопротивлени л . Изменение (Электрического сопротивлени нити св зано с изменением температуры дТ в соответствии с формулойWith the presence of the preliminary tension force of the thread, the change in its dimensions along the spine causes an additional change in the electrical resistance l. Change (The electrical resistance of the filament is related to the temperature change dT in accordance with the formula
oPo 7« T: т oPo 7 "T: t
где Кр - сопротивление нити при 20°С удельный температурный кйэффициент сопротивлени нити; where Kp is the thread resistance at 20 ° С, the specific temperature coefficient of the thread resistance;
К - коэффициент тензочувств.ительности НИТИ;K - coefficient of strain gage NITI;
ТГ - коэффициент линейного расширени материала нити.TG is the coefficient of linear expansion of the material of the thread.
