| YJTW 系列耐酸、耐高溫壓力表 YJTW Series Acid Resistant & High Temperature Resistant Pressure Meter 簡介 本儀表廣泛應用于石油、化工、化纖、冶金、電站等工業部門中對耐酸、耐高溫有較高要求的工藝流程中測量各中流體介質的壓力。 耐酸壓力表的零件全部采用不銹鋼材料制成，具有較強的耐腐蝕性能，適用于檢測腐蝕性較強介質的壓力和在外部腐蝕環境中使用。 耐高溫壓力表的零件全部采用不銹鋼材料制成，導壓系統采用焊接工藝，具有優良的耐腐蝕性能。適用于對腐蝕性較強的介質和錫釬焊工藝不宜采用的高溫介質或溫度較高環境中的壓力檢測。 Brief introduction: This sort of meter is used to measure pressure of various liquid mediums, which are widely used in technique flows of industry departments, such as oil industry, chemical industry, chemical fiber, metallurgy, electricity station, etc, which require higher acid-resistant performance. Parts of acid resistant pressure meter are all made of stainless steel material, so the meters acid-resistant performance is much better and can be used to measure pressure of medium with powerful corrosion. Parts of high temperature resistant pressure meter are all made of stainless steel material, and welding technique is adopted in its pressure leading system, so the meters corrosion resistant performance is good. This sort of meters can be used to measure pressure of following mediums: medium with strong corrosion, high temperature medium that is not suitable for braze welding technique, or medium with high temperature. 主要技術參數 Principal technical parameters | 型號 Model | 精確度 Accuracy | 使用環境條件 Condition of applicable environment | 溫度影響 Temperature influence | 標度范圍 Measuring ranges（MPa） | | YJTW-100 | 1.6、2.5 | -40～70℃， -40～+200℃ （耐高溫）, 相對濕度不大于85% （High temperature resistants）Relative humidity: ≤85% | 使用溫度如偏離20±5℃ 其溫度附加誤 差不大于0.4%/10℃ with temperature departure of 20±5℃ the additional errorshall be less than 0.4%/10℃. | 0～0.6;0～1;0～1.6; 0～2.5;0～4;0～6; 0～10;0～25;0～40;0～60 | | YJTW-150 | 0～0.6;0～1;0～1.6; 0～2.5;0～4;0～6; 0～10;0～25;0～40;0～60 | 標記示例：YTS-150 耐酸壓力表，公稱直徑150mm。 Marking instance：YTS-150 Production computer coding：1400060302 Acid resistant pressure meter, nominal diameter is 150mm.
