ABB 266DDH Pressure Transmitter

ABB 266DDH Differential Pressure Transmitter with Direct-Mount Diaphragm Seal

The ABB 266DDH is a high-performance differential pressure transmitter engineered with a direct-mounted diaphragm seal for accurate and stable measurements on vessels and tanks. Designed for demanding industrial environments, it combines exceptional accuracy, long-term reliability, and advanced configuration features such as WirelessHART communication and Through-The-Glass (TTG) technology.

Key Features & Technical Advantages

High Accuracy & Long-Term Stability

• Base accuracy: up to ±0.06% of calibrated span

• Long-term stability: ±0.15% of URL over 10 years, reducing recalibration and maintenance costs

Advanced Communication & Configuration

• Supports HART®, PROFIBUS PA, FOUNDATION Fieldbus, and WirelessHART

• TTG (Through-The-Glass) configuration allows safe field setup using the local LCD without opening the enclosure—ideal for hazardous areas

Safety & Reliability

• SIL 2 / SIL 3 certified (IEC 61508, TÜV Nord) for safety-critical applications

• Modular electronics with in-field replaceable modules and auto-configuration for faster maintenance and improved plant uptime
