ABB’s S26 remote and direct mount diaphragm seals are engineered to extend the capabilities of pressure transmitters in demanding process environments. Designed for use with 2600T and P-Series transmitters, these seals enable accurate gauge, differential, and absolute pressure measurements while protecting sensitive electronics from harsh process conditions.

Key Features:

• All-Welded Construction: Taylor’s proven “All-Welded” technology ensures long-term reliability and leak-free performance.
• Flexible Mounting Options: Available in direct mount or remote configurations using capillary systems.
• Wide Range of Seal Types:
  • Wafer seals (S26WA, S26WE)
  • Rotating flange seals (S26Rx, S26RR)
  • Fixed flange seals (S26FA, S26FE)
  • Sanitary seals (S26SS)
  • Pulp & paper seals (S26KN)
  • Urea service seals (S26PN)
  • Button type and off-line connection seals

• Customizable Process Connections: Supports ASME, EN, and JIS flanges, chemical tees, and threaded fittings.
• Corrosion-Resistant Capillaries: Stainless steel with spiral armor or PVC jacket for added protection.
• FDA-Approved Fill Fluids: Available for food, dairy, pharmaceutical, and biotech applications.

Functional Benefits:

• Process Isolation: Prevents direct contact between process media and transmitter, ideal for high temperature, viscous, or hazardous fluids.
• Enhanced Measurement Capabilities: Enables flow, level, density, and interface level measurements.
• Improved Safety & Maintenance: Allows transmitter installation away from process for easier access and reduced exposure to hazards.
• Application Versatility: Suitable for industries including oil & gas, chemical, food & beverage, pulp & paper, and pharmaceuticals.

Performance Considerations:

• Accuracy is minimally affected by diaphragm stiffness relative to sensor stiffness.
• Selection criteria include temperature effects, dynamic response, and fill fluid compatibility.
• Designed to maintain performance even in extreme conditions.
