YA系列氨压力表YA
Series Ammonia Pressure Meter
简介
氨压力表为氨专用仪表，用于测量对普通碳钢、合金结构钢、澳氏体类不锈钢及锡铅合金钎焊料无腐蚀作用，非结晶和凝固的氨气、氨液介质的压力。主要适用于化肥生产过程中设备或其他中用来测量氨的液体、气体或其混合物等的压力。
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.
结构原理
仪表由导压系统（包括接头、弹簧管等）、传动机构、指示装置和外壳等组成。
当被测介质作用于弹簧管时，其管端产生相应的弹性变形——位移，经传动机构放大后，由指示装置在度盘上把被测压力指示出来。
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.
