266HSH — ABB 266HSH High Static Differential Pressure Transmitter
The ABB 266HSH High Static Differential Pressure Transmitter is engineered for the most demanding process measurement applications across Saudi Arabia's hydrocarbon and industrial sectors. Designed to ARAMCO SAES-I-010 instrumentation specifications, this transmitter delivers exceptional accuracy and reliability in the extreme conditions encountered at Saudi Aramco upstream facilities, SABIC petrochemical complexes, and NEOM smart city infrastructure projects. The 266HSH handles differential pressures up to 2500 kPa with a static pressure rating of 32 MPa, making it ideal for high-pressure pipeline measurement applications throughout the Kingdom.
The transmitter incorporates ABB's advanced piezoresistive sensor technology with hermetically sealed oil-filled capillary systems that maintain calibration stability in Saudi Arabia's harsh desert environment. Operating reliably from -40°C to +85°C ambient temperature, the 266HSH performs flawlessly in the extreme summer heat of Rub' al Khali field operations and Jubail Industrial City process plants. The all-stainless steel wetted parts construction resists the corrosive hydrogen sulfide (H₂S) concentrations found in Saudi sour crude processing at Abqaiq and Haradh gas plants.
With Foundation Fieldbus, HART 7, and PROFIBUS PA communication options, the ABB 266HSH integrates seamlessly with the distributed control systems deployed across Saudi Aramco's Master Gas System and SEC power generation facilities. The transmitter meets IEC 62443 cybersecurity standards required for Vision 2030 digital transformation initiatives and supports the Industrial Internet of Things (IIoT) architectures being deployed at NEOM's industrial zones. Two-wire 4-20mA output with HART superimposition enables remote diagnostics and predictive maintenance from central control rooms in Dhahran and Dammam.
Razz Middle East stocks the complete 266HSH product range with Saudi Aramco Material Master numbers pre-registered. Our Dammam technical center provides local calibration services traceable to SASO standards, and our field service teams are certified for installation in ARAMCO restricted areas across the Eastern Province, Riyadh, and Yanbu. The transmitter carries SIL 2 certification per IEC 61508 for safety instrumented system applications at SABIC facilities and Saudi Aramco critical process units.

Key Features & Benefits
- High static pressure capability of 32 MPa enables installation on high-pressure Saudi Aramco crude oil trunk lines and SABIC ethylene cracker feeds without separate isolation manifolds.
- Drift performance of <0.1% per year over 5 years reduces calibration intervals at remote desert field locations where logistics costs are high.
- Integral LCD display with configurable units supports local indication in Saudi process facilities without requiring handheld communicators.
- Multi-sensor diagnostic capability detects sensor degradation, plugged impulse lines, and process anomalies before they cause measurement errors.
- Dual-compartment housing separates electronics from terminal connections, allowing safe wiring in hazardous areas classified per ARAMCO RP-14.
- Factory multi-point calibration certificate traceable to national standards shipped with every unit for SWCC and SEC compliance records.
