（1）U型氣壓計(jì)。U形氣壓計(jì)由于形狀像英文大寫(xiě)字母U而得名，實(shí)際上是兩個(gè)有刻度的連通的玻璃管。加入液體后，一頭與大氣連通，另一頭與被測(cè)的氣體連通，利用兩個(gè)玻璃管中的液面差測(cè)量氣壓差。結(jié)合已知的大氣壓數(shù)值，就可以得到被測(cè)的氣壓值。U形氣壓計(jì)中常用的液體是純水、水銀、乙醇等。同樣長(zhǎng)度的U形氣壓計(jì)，液體的密度越大，量程越大，精確度越低；液體的密度越小，量程越小，精確度越高。所以，應(yīng)該根據(jù)量程和精確度選用適當(dāng)?shù)囊后w。水銀有毒，如果使用水銀需要適當(dāng)防護(hù)。
(1) U type barometer. U shaped pressure gauge because of the shape of the English capital letters U and the name, in fact, is the two of the scale of the glass tube. After adding a liquid, a head is connected with the atmosphere, and the other end is connected with the gas to be measured, and the difference of the liquid level in the two glass tube is measured. By combining the known atmospheric pressure values, the measured pressure values can be obtained. The liquid in the U type barometer is pure water, mercury, ethanol, etc.. The same length of U - shaped barometer, the greater the density of the liquid, the larger the range, the lower the accuracy; the smaller the density of the liquid, the smaller the range, the higher the accuracy. Therefore, it should be based on the range and accuracy of the appropriate choice of liquid. Mercury is poisonous, and if you need to use mercury, it needs to be protected.
（2）斜管微壓計(jì)。斜管微壓計(jì)可以理解為U形壓力機(jī)的變形。一般情況下，U形壓力計(jì)的玻璃管垂直讀數(shù)，斜管微壓計(jì)的玻璃管傾斜讀數(shù)。玻璃管傾斜后，同樣的壓差在玻璃管中顯示的距離較大，讀數(shù)的精確度較高。所以與U形壓力計(jì)比較，斜管微壓計(jì)的讀數(shù)精確度要高一些。
(2) inclined tube. The inclined tube micro pressure gauge can be understood as the deformation of the U type press. Under normal circumstances, the U - shaped gauge of the glass tube is vertical to the reading, and the inclined tube is tilted to the glass tube. After the glass tube is inclined, the same pressure difference is shown in the glass tube, and the accuracy is higher. So, with the U - type pressure gauge, the accuracy of the inclined tube is higher.
（3）精密微壓計(jì)。精密微壓計(jì)結(jié)構(gòu)比較復(fù)雜，雖然也是用純水顯示壓力，然而采用放大鏡瞄準(zhǔn)、螺紋微調(diào)、游標(biāo)讀數(shù)，可以達(dá)到更高的精確度。
(3) precision micro pressure gauge. Precision micro pressure meter structure is more complex, although it is also used to show the pressure, but the use of magnifying glass targeting, thread tuning, cursor reading, can achieve higher accuracy.
（4）彈性氣壓計(jì)。彈性氣壓計(jì)是利用物體彈性制造的氣壓計(jì)。彈性氣壓計(jì)種類(lèi)繁多，應(yīng)用范圍非常廣泛。
(4) elastic barometer. The elastic barometer is an air pressure gauge made of elastic objects. The elastic pressure gauge has a wide range of applications.
（5）壓差計(jì)。壓差計(jì)與壓力計(jì)經(jīng)常是可以通用的。有時(shí)可以測(cè)出壓力計(jì)算出壓差，有時(shí)又可以測(cè)出壓差計(jì)算出壓力。U形壓力機(jī)就是凈化鋁材配件 http://www.jnjkjh.com/ 中一種典型的通過(guò)測(cè)壓差計(jì)算壓力的儀器。
(5) differential pressure gauge. Differential pressure gauge and pressure gauge are often used. Sometimes it can measure the pressure difference, sometimes it can measure the pressure difference. U - shaped press is a typical instrument for measuring the pressure of the pressure in the purification of aluminum parts.
（5）電子壓力計(jì)。電子壓力計(jì)一般是通過(guò)壓力傳感器、電子線路和顯示器直接用數(shù)字顯示壓力的數(shù)值。
(5) electronic pressure gauge. Electronic pressure gauge is generally used to display the pressure by pressure sensor, electronic circuit and display.
