ABB Differential Pressure Transmitter 266DSH – High-Accuracy DP Transmitter for Industrial Applications

The ABB 266DSH Differential Pressure Transmitter is a premium, long-term stability device engineered for demanding industrial environments across oil & gas, petrochemical, power plants, desalination facilities, and water treatment plants in Saudi Arabia. Known for its exceptional accuracy and robust design, the 266DSH is widely trusted for reliable measurement of differential pressure, flow, level, density, and other critical process parameters.

Key Features & Advantages

✔ Through-The-Glass (TTG) Technology

The 266DSH features ABB’s advanced TTG local configuration system, allowing technicians to program, zero trim, and adjust settings without opening the housing. This reduces downtime, improves safety, and cuts maintenance costs—especially valuable for harsh or hazardous Saudi industrial environments.

✔ Exceptional Accuracy & Long-Term Stability

Standard accuracy: ±0.06% of calibrated span
Optional high-precision model: ±0.04%
10-year stability guarantee, ensuring reliable, drift-free measurements even in extreme conditions.

✔ SIL2 / SIL3 Safety Certification

Certified by TÜV Nord according to IEC 61508, the transmitter is suitable for safety-critical loops, shutdown systems, and high-risk process applications.

✔ Flexible Communication Protocols

The ABB 266DSH supports:

HART®
PROFIBUS PA
FOUNDATION Fieldbus
This ensures seamless integration with modern DCS and PLC systems used across Saudi industries.

✔ WirelessHART® Version Available

A WirelessHART model provides:

Up to 10 years of battery life
32-second update rate
Easy installation for remote or hazardous locations
This makes it ideal for refineries, offshore platforms, and difficult-to-access pipelines.

✔ Advanced Diagnostic Functions

Comes with Plugged Impulse Line Detection (PILD) standard, enabling early detection of potential blockage, supporting predictive maintenance, and reducing unplanned shutdowns.
