福建省漳州仪表厂生产的NNG—01型光电浓度变送器,厂家不装备温度自动补偿装置,但可以用简便的方法实现温度自动补偿。 我们知道,黑液的浓度随着温度的升高而降低,其关系式为: B_(15)=Bt+(t-15)K式中:B_(15)——黑液在15°C时的浓度; Bt——黑液在t°C时的浓度; NNG-01 photoelectric concentration transmitter produced by Zhangzhou Instrument Factory in Fujian Province is not equipped with automatic temperature compensation device, but the temperature can be automatically compensated by a simple and convenient method. We know that the concentration of black liquor decreases with increasing temperature, the relationship is: B_ (15) = Bt + (t-15) K Where: B_ (15) - Black liquor at 15 ° C Concentration; Bt - concentration of black liquor at t ° C;
