作為新興壓力變送器的一種，智能壓力變送器在市場(chǎng)上的應(yīng)用前景越來(lái)越好。智能壓力變送器能夠迅速搶占市場(chǎng)的重要原因就在于，與傳統(tǒng)壓力變送器相比，它的性能優(yōu)勢(shì)表現(xiàn)的更為明顯，主要可以概括為測(cè)量精度準(zhǔn)、穩(wěn)定性能良好、使用方便等等。為此，我們必須對(duì)這類變送器在濕度方面的測(cè)量方法有一定程度的了解，這樣可以大大提高智能壓力變送器的測(cè)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、露點(diǎn)測(cè)量法

       First,dew point measurement method

       所謂露點(diǎn)測(cè)量法，指的是智能壓力變送器對(duì)濕空氣達(dá)到飽和狀態(tài)時(shí)的溫度進(jìn)行測(cè)量的方法。這種測(cè)量方法，主要利用了熱力學(xué)的相關(guān)原理。它的優(yōu)點(diǎn)在于，測(cè)量結(jié)果的準(zhǔn)確性高、測(cè)量的范圍較廣。但是這種測(cè)量方法的缺陷就在于，投入成本過(guò)大，且需要與相關(guān)儀器進(jìn)行配套使用，增加了測(cè)量的操作難度。

       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、干濕球測(cè)量法

       Second,dry and wet ball measurement

       這種測(cè)量濕度的方法出現(xiàn)的時(shí)間很早，因而也是應(yīng)用較多的一種。實(shí)際上，它屬于間接測(cè)量方法的一種。與露點(diǎn)測(cè)量法相比較，它的準(zhǔn)確性要低上很多。

       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、飽和鹽法

       Third,the saturated salt method

       它屬于靜態(tài)法的一種，也是對(duì)濕度進(jìn)行測(cè)量的方法中較為常見的一種，具有操作簡(jiǎn)便的特點(diǎn)。但是，當(dāng)智能壓力變送器用于濕度測(cè)量時(shí)，它對(duì)液體、氣體的平衡性要求是十分嚴(yán)格的。因而，會(huì)花費(fèi)大量的時(shí)間在濕度平衡這一點(diǎn)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、雙壓法及雙溫法

       Four,double pressure method and double temperature method

       智能壓力變送器對(duì)濕度的測(cè)量，主要利用了熱力學(xué)中關(guān)于P、V、T三者的平衡遠(yuǎn)離。這種測(cè)量方法與飽和鹽法一樣，需要花費(fèi)很長(zhǎng)的時(shí)間進(jìn)行干、濕空氣的平衡。但是，與干濕球測(cè)量法不同的是，由于應(yīng)用了現(xiàn)代測(cè)量技術(shù)，因而在測(cè)量精準(zhǔn)度上要高的多。但是，它.大的弊端就體現(xiàn)在相關(guān)設(shè)備的制造上，不僅制造流程復(fù)雜，而且制造成本高，耗費(fèi)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.
