优势
  1. 全不锈钢接液,耐水汽、弱酸弱碱、纯水、高纯介质;

  2. 禁油脱脂处理,可用于氧气系统、半导体高纯气体、食品洁净管路

  3. 日本原厂整机,波登管焊接结构,耐压稳定。

⚠️ 重要限制(选型必看)
  1. 无充油,不耐持续振动;设备脉动大、震动剧烈场合,不能替代 AVU耐震系列;震动环境建议增加缓冲器或更换耐振款;

  2. 禁油表严禁和普通液压油管路混用,安装工具必须脱脂,禁止手触碰接液内腔;

  3. R1/4 锥螺纹,密封依靠螺纹锥面,安装建议搭配 PTFE 生料带,不可用力过度拧裂接头;

  4. 介质兼容性:不可用于浓盐酸、高浓度氯离子长期工况;不适用强氧化性强酸。

四、典型应用场景

  • 氧气、氩气、氮气等高纯气体管路监测

  • 纯水 / 超纯水、水乙二醇无油液压系统

  • 半导体、洁净设备、食品无菌生产线

  • 化工低压腐蚀性流体压力监测

五、替代选型参考(如需备库 / 替换)

  1. 现场震动大 → 同规格更换:AVU-R1/4-60×1.5MPa SUS316 禁油(干式耐振型)

  2. 需要面板安装 → 选用 BU 系列(轴向带法兰)

  3. 螺纹需要 G1/4 平行螺纹 → 订货时变更螺纹规格

S11-2-4Internal Type Code (S11 Type A Gauge)Internal drawing & order classification code; Open dry construction, no electric contact, standard borosilicate glass window, standard accuracy

2. Core Technical Parameters

  • Accuracy Class: ±1.6% F.S. (JIS B7505)

  • Construction: Type A Bottom Entry Without Flange (Radial Outlet, No Mounting Flange)

  • Wetted Material: SUS316 (Connection & Bourdon Tube)

  • Case Material: Electroplated Stainless Steel

  • Window: Standard Borosilicate Glass (Non-sealed non-oil-filled anti-vibration structure)

  • Filling: Dry type, no filling liquid (Oil-free version undergoes full-process degreasing cleaning)

  • Operating Temperature: -5℃ ~ +60℃ (normal working range)

  • Protection Class: IP43

  • Thread Standard: JIS R Thread (PT1/4, NOT directly interchangeable with G1/4)

3. Key Features & Warnings

Advantages
  • All stainless steel wetted parts, resistant to moisture, weak acid, weak alkali, pure water and high-purity media.

  • Degreased oil-free treatment, applicable to oxygen systems, semiconductor high-purity gas pipelines and food sanitary piping.

  • Original Japan complete unit, welded bourdon tube construction for stable pressure resistance.

⚠️ Important Restrictions (For Selection Reference)
  • Dry type without filling liquid, NOT suitable for continuous vibration. For systems with severe pressure pulsation or heavy vibration, cannot replace AVU anti-vibration series. Install a pulsation damper or switch to anti-vibration model under vibrating conditions.

  • Oil-free gauge must never be used with ordinary hydraulic oil circuits. All installation tools shall be degreased; avoid touching internal wetted cavity by hand.

  • R1/4 taper thread relies on conical surface for sealing. PTFE tape is recommended during installation. Do not over-tighten to prevent thread cracking.

  • Media Compatibility: Not suitable for long-term service with concentrated hydrochloric acid or high chloride ion media; incompatible with strong oxidizing acids.

4. Typical Applications

  • High-purity gas pipeline monitoring: Oxygen, Argon, Nitrogen, etc.

  • Pure water / UPW, oil-free water-glycol hydraulic systems

  • Semiconductor equipment, clean equipment, food aseptic production lines

  • Low-pressure corrosive fluid measurement in chemical industry

5. Alternative Selection Reference (Stock / Replacement)

  • Heavy vibration on site → Replace with equivalent spec: AVU-R1/4-60×1.5MPa SUS316 Oil-Free (Dry Anti-vibration Type)

  • Panel mounting required → Select BU Series (back entry with flange)

  • G1/4 parallel thread required → Specify thread change when placing orders
