作为新兴压力变送器的一种，智能压力变送器在市场上的应用前景越来越好。智能压力变送器能够迅速抢占市场的重要原因就在于，与传统压力变送器相比，它的性能优势表现的更为明显，主要可以概括为测量精度准、稳定性能良好、使用方便等等。为此，我们必须对这类变送器在湿度方面的测量方法有一定程度的了解，这样可以大大提高智能压力变送器的测量效率。

       As an emerging pressure transmitter,the application of smart pressure transmitters in the market is getting better and better.The important reason why the intelligent pressure transmitter can quickly seize the market is that its performance advantage is more obvious than that of the traditional pressure transmitter.It can be summarized as accurate measurement accuracy,good stability,easy to use,etc..To this end,we must have a certain degree of understanding of the humidity measurement methods of such transmitters,which can greatly improve the measurement efficiency of intelligent pressure transmitters.

       一、露点测量法

       First,dew point measurement method

       所谓露点测量法，指的是智能压力变送器对湿空气达到饱和状态时的温度进行测量的方法。这种测量方法，主要利用了热力学的相关原理。它的优点在于，测量结果的准确性高、测量的范围较广。但是这种测量方法的缺陷就在于，投入成本过大，且需要与相关仪器进行配套使用，增加了测量的操作难度。

       The so-called dew point measurement method refers to the method of measuring the temperature of the wet air when the wet air reaches saturation.This measurement method mainly utilizes the relevant principles of thermodynamics.Its advantages are that the measurement results are highly accurate and the measurement range is wide.However,the drawback of this measurement method is that the input cost is too large,and it needs to be used in conjunction with related instruments,which increases the difficulty of measurement.

       二、干湿球测量法

       Second,dry and wet ball measurement

       这种测量湿度的方法出现的时间很早，因而也是应用较多的一种。实际上，它属于间接测量方法的一种。与露点测量法相比较，它的准确性要低上很多。

       This method of measuring humidity occurs very early and is therefore one of the more widely used.In fact,it is one of the indirect measurement methods.Compared with the dew point measurement method,its accuracy is much lower.

       三、饱和盐法

       Third,the saturated salt method

       它属于静态法的一种，也是对湿度进行测量的方法中较为常见的一种，具有操作简便的特点。但是，当智能压力变送器用于湿度测量时，它对液体、气体的平衡性要求是十分严格的。因而，会花费大量的时间在湿度平衡这一点上。

       It is a kind of static method,and it is also one of the more common methods for measuring humidity,and it has the characteristics of simple operation.However,when a smart pressure transmitter is used for humidity measurement,its balance of liquid and gas requirements is very strict.Therefore,it takes a lot of time to balance the humidity.

       四、双压法及双温法

       Four,double pressure method and double temperature method

       智能压力变送器对湿度的测量，主要利用了热力学中关于P、V、T三者的平衡远离。这种测量方法与饱和盐法一样，需要花费很长的时间进行干、湿空气的平衡。但是，与干湿球测量法不同的是，由于应用了现代测量技术，因而在测量精准度上要高的多。但是，它.大的弊端就体现在相关设备的制造上，不仅制造流程复杂，而且制造成本高，耗费的人力、物力都是很大的。

       The measurement of humidity by the intelligent pressure transmitter mainly utilizes the balance of P,V and T in thermodynamics.This measurement method,like the saturated salt method,takes a long time to balance the dry and wet air.However,unlike the dry-wet ball measurement method,the measurement accuracy is much higher due to the application of modern measurement techniques.However,its biggest drawback is reflected in the manufacture of related equipment,not only the manufacturing process is complicated,but also the manufacturing cost is high,and the labor and material resources are very large.
