三、关键特性 & 使用警示
全不锈钢接液,耐水汽、弱酸弱碱、纯水、高纯介质;
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;
日本原厂整机,波登管焊接结构,耐压稳定。
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;
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;
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;

1. Model Code Breakdown
| Code Segment | Definition | Supplementary Remarks |
|---|---|---|
| AT | Base Series – Dry Standard Pressure Gauge (Non-Filled) | Not anti-vibration oil-filled type |
| R1/4 | Connection Thread: R1/4 (PT1/4) Taper External Pipe Thread, Bottom Radial Connection | Type A, no flange, direct pipe mounting |
| 60 | Dial Diameter: φ60 mm | Compact size widely used in industry |
| 1.5MPa | Measuring Range: 0 ~ 1.5 MPa | Uniform scale marked in MPa |
| SUS316 | Wetted Components: Connection + Bourdon Tube = SUS316 Stainless Steel; Case: SUS304 | Good corrosion resistance for water, mildly corrosive fluids and high-purity gas |
| Oil-Free | Oil-Free / Degreased Specification | No grease inside movement and wetted parts; Must not contact lubricants. Specially for oxygen, high-purity nitrogen and special gas service |
| S11-2-4 | Internal 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
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.
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
