YA系列氨壓力表YA 簡介
氨壓力表為氨儀表，用于測量對普通碳鋼、合金結構鋼、澳氏體類不銹鋼及錫鉛合金釬焊料無腐蝕作用，非結晶和凝固的氨氣、氨液介質的壓力。主要適用于化肥生產過程中設備或其他中用來測量氨的液體、氣體或其混合物等的壓力。
Brief Introduction:
Ammonia pressure meter is a special meter for ammonia, used to measure various non-crystallized and solidified medium that have no corrosive action on common carbon system steel, alloy structural steel, Austenite stainless steel, or tinsel bar solder, principally applicable for measuring pressures of liquefied ammonia, gas, or other mixtures in cooling equipments in chemical fertilizer production.
結構原理
儀表由導壓系統（包括接頭、彈簧管等）、傳動機構、指示裝置和外殼等組成。
當被測介質作用于彈簧管時，其管端產生相應的彈性變形——位移，經傳動機構放大后，由指示裝置在度盤上把被測壓力指示出來。
Configuration principle
This instrument consists of pressure pilot system （comprising joints, spring pipe, and so on）, running gear, indicating device, and outer housing, etc.
When the medium acts on the spring pipe, corresponding elastic deformation or displacement occurs at the pipe end accordingly, which is amplified through running gear and displayed in indicating devices dial as the pressure being tested.
