在进行有关不同高度的大气压条件的模型实验研究时,必须测量小数值的绝对压力。为此采用了热电的和电离的压力转换器,这种转换器在使用标准分度特性时表明的误差为被测值的(10～40)%。标准分度特性的使用,使测量结果的误差大大地增加。为提高测量结果的可靠性,必需用保证压力有 When conducting model experimental studies on atmospheric conditions at different altitudes, the absolute value of the decimal value must be measured. For this purpose, a pyroelectric and ionization pressure transducer is used which shows an error of 10 to 40% of the measured value when using standard graduation characteristics. The use of standard graduation features greatly increases the error in measurement results. In order to improve the reliability of the measurement results, it is necessary to guarantee the pressure there
