266DDHFSSA2A1E1L1C1H3 | ABB Differential Pressure Transmitter

Key Features:

1. Direct-Mounted Diaphragm Seal:

   • The transmitter can be equipped with a diaphragm seal on the high-pressure side and a standard process connection, or a remote-mounted diaphragm seal on the low-pressure side.
   • This configuration provides high flexibility and reliability in applications where direct pressure measurements are required.

2. Advanced Diaphragm Seal Design:

   • ABB’s diaphragm seals are renowned for their advanced design, which eliminates threaded connections or gaskets that could lead to leakage problems or measurement drift over time.
   • The reduced oil filling minimizes temperature errors, improving overall measurement accuracy.

3. Self-Configuration and Hot-Swappable Display:

   • The transmitter features a self-configuration function on the circuit board, allowing for on-site replacement and minimizing downtime.
   • Hot-swappable field display allows for easy configuration and adjustments without powering down the system, saving time and reducing maintenance costs.
   • TTG window technology enables operation in explosion-proof environments without needing to open the cover.

4. Safety Certifications:

   • SIL2/SIL3 Certified: The Differential Pressure Transmitter meets the IEC61508 standard for functional safety, with certification from TÜV Nord. This makes it suitable for use in safety applications.

5. WirelessHART Communication:

   • The 266DDH supports WirelessHART, which reduces wiring complexity and installation time. This is especially useful for remote or hard-to-reach locations, saving construction costs and improving installation efficiency.

6. Battery Life:

   • The 266DDH can operate for up to 10 years with a 32-second update rate, making it a cost-effective, long-term solution for differential pressure measurement.

7. Multiple Output Signals:

   • Output signal options include:
     • 4-20mA + HART
     • Profibus PA
     • Foundation Fieldbus
     • WirelessHART
   • These protocols offer compatibility with various industrial control systems and provide easy transmitter upgrades.

8. Pressure Range and Accuracy:

   • Basic Accuracy: ±0.06%
   • Pressure Range: From 0.05 to 16,000 kPa, providing versatility across many applications.

9. Compliance:

   • PED Class III Compliant: Meets the European Pressure Equipment Directive (PED) requirements for safe operation in various pressure systems.

Applications:

• Process Control: Ideal for differential pressure measurement in industries such as oil and gas, chemical processing, power generation, and water treatment.
• Safety-Critical Systems: Suitable for applications where functional safety is paramount, such as in refineries, chemical plants, and power stations.
• Remote Monitoring: WirelessHART functionality is perfect for remote installations or challenging environments where wired connections may be impractical.
