ABB 266MSH Differential for high static pressure

ABB 266MSH Differential for high static pressure

The ABB 266MSH Differential for high static pressure is a high-performance differential pressure transmitter engineered for demanding applications with extreme static pressure conditionsABB. It belongs to the 2600T Series and integrates advanced multisensor technology to deliver precise, reliable measurements of differential pressure, static pressure, and process variables.

Core Features & Performance

High Static Pressure Rating: Maximum working pressure (MWP) of 41 MPa (410 bar / 5945 psi), ideal for high-pressure pipelines, power plants, and oil & gas operations.

Exceptional Accuracy: Base accuracy from ±0.06% of calibrated span, with optional high-accuracy variantsABB.

Wide Turndown Ratio: Up to 100:1 turndown, enabling flexible measurement across varying process conditions.

Long-Term Stability: 10-year stability of 0.15% URL, minimizing calibration and maintenance needs.

Multisensor Capability: Simultaneously measures differential pressure and absolute pressure; sensor data compensates for environmental effects.

Key Functional Advantages

Field-Configurable Electronics: In-field replaceable electronics module with auto-configuration, boosting plant productivity and reducing downtimeABB.

TTG (Through The Glass) Technology: Intuitive local configuration via the LCD display without removing the front cover, simplifying field setupABB.

Plugged Impulse Line Detection (PILD): Standard predictive maintenance feature to alert users of impending line blockagesABB.

Safety Certification: TÜV Nord-certified SIL2/SIL3 (IEC 61508), suitable for safety-critical process loopsABB.

Protocol Compatibility: Supports HART®, PROFIBUS PA, and FOUNDATION Fieldbus for seamless integration with control systemsABB.

Regulatory Compliance: Fully compliant with PED Category III for pressure equipment safety.
