NAGANO KEIKI Japan 

 General Industrial Pressure Gauges AE20 Series

Model: AE20-131-0.6MPA /  AE20-131-1.6MPA ...

The NAGANO KEIKI pressure gauge AE20 series is an A-frame vertical ordinary pressure gauge featuring a 100mm outer diameter dial and a simple, reliable Bourdon tube mechanism. It is compliant with the Japanese Industrial Standard JIS B 7505-1, making it a widely trusted choice for measuring gas or liquid pressure in diverse industrial setups.

Pressure gauge NKS AE20-131-1MPA

• General Industrial Machinery: Hydraulic packs, pneumatic loops, air compressors, and utility systems.
• Fluid Dynamics Monitoring: Pump discharge, water supply pipelines, and non-corrosive gas delivery lines. 
• Special Treatment Configurations:
  • Can be specifically ordered as "Use No Oil" for oxygen piping systems to prevent combustion risks.
  • Available as "Use No Oil + Corrosion-Proof" configurations specifically for acetylene service lines.

• Dial Size: 100mm outer diameter 
• Case Profile: A Frame (Upright, stem mount, no front flange/brim) 
• Accuracy Class: ±1.6% Full Scale (F.S.) (Or Class 1.5 equivalent depending on region) 
• Enclosure Protection: Equivalent to IP32 
• Standard Process Connections: G3/8B, G1/2B, or R1/2 
• Wetted Materials:
  • Bourdon Tube: Brass (C6872) for standard/lower ranges; Stainless Steel (SUS 316) for high-pressure systems ≥ 4MPa
  • Socket/Stock: Brass (C3771) 
• Case Material: Electrogalvanized steel sheet (SECC) with a black outer finish

HOW TO ORDER:

• High Mechanical Simplicity: The internal architecture relies on direct Bourdon tube elastic deformation linked to a rotary geared pointer mechanism. The absence of overly complex linkages minimizes mechanical wear and ensures long-term operational ease. 
• Strict Standardization (JIS B 7505-1): Manufactured in accordance with official Japanese Industrial Standards, guaranteeing universal installation compatibility, reliable dimensional tolerance, and strict ±1.6% Full Scale accuracy. [
• Unique Identification Traceability: Every dial face features a dedicated 7-digit part number printed directly under the NKS trademark. This design simplifies on-site inspection, inventory checking, and direct replacement ordering. 
• Material Scaling Adaptability: The internal wetted materials scale based on system load to optimize safety. Low-pressure units use flexible, sensitive brass elements, while high-pressure variants (≥ 4MPa) automatically shift to high-tensile SUS 316 Stainless Steel to avoid tube rupture. 
• Official Type Approval Certification: Gauges can be ordered with a Verification Standard Inspection Mark attached directly by the manufacturer for deployment in environments requiring official certification or regulatory compliance checkmarks. 
• Specialized System Cleanness Options: Available with "Use No Oil" (oxygen lines) and "Use No Oil + Corrosion-Proof" (acetylene systems) processing modifications to ensure safety in combustible gas environments.
