🔬 ABB 266DRHFSRRRA1E1L1B1C1H3 Remote Seal Differential Pressure Transmitter
The ABB 266DRH is an advanced differential pressure transmitter with remote diaphragm seals, engineered for challenging process conditions involving corrosive fluids, high temperatures, or viscous media. Featuring ±0.06% base accuracy, NACE-certified 316L stainless steel wetted parts, and ATEX intrinsic safety approval, this transmitter delivers reliable measurements in the 0.67-40 kPa range for critical applications in oil & gas, chemical processing, and pharmaceutical manufacturing.
🔧 Technical Specifications
REMOTE SEAL CONFIGURATION
🔹 Model Code: 266DRHFSRRRA1E1L1B1C1H3
🔹 Transmitter Type: Differential Pressure with Remote Seals
🔹 Base Accuracy: ±0.06% of calibrated span
🔹 Measurement Range: 0.67 to 40 kPa (6.7-400 mbar, 2.67-160 in H₂O)
🔹 Diaphragm Material: AISI 316L SS (NACE certified)
🔹 Fill Fluid: Silicone oil
🔹 Process Flanges: AISI 316L SS (two seals construction)
🔹 Max Working Pressure: 16 MPa (160 bar, 2320 psi)
🔹 Housing: Aluminum alloy (barrel version)
🔹 Output Signal: 4-20mA with HART digital communication
🔹 Display: Integral digital LCD
🔹 Certifications: ATEX Ex ia IIC T6, NACE MR0175/ISO 15156, EN 10204-3.1
🏭 Specialized Applications
Corrosive Chemical Processing: Measures differential pressure across reactors, distillation columns, and filtration systems handling sulfuric acid, hydrochloric acid, and caustic solutions where NACE-certified 316L stainless steel wetted parts prevent material degradation and ensure 10+ year service life in aggressive environments.
High-Temperature Steam Systems: Monitors steam flow and pressure drop in boilers, superheaters, and turbine inlet lines operating at 200-400°C where remote seals isolate transmitter electronics from extreme temperatures, extending MTBF to 150,000+ hours versus direct-mounted transmitters failing in 2-3 years.
Viscous & Slurry Applications: Tracks level and flow in storage tanks, crystallizers, and thickeners containing heavy oils, polymers, and mineral slurries where remote seals with extended diaphragms prevent impulse line plugging that causes 60% of measurement failures in conventional DP systems.
Pharmaceutical Clean-in-Place (CIP): Provides sanitary pressure measurement in bioreactors, fermenters, and sterile filtration systems with flush-mounted diaphragms meeting FDA 21 CFR Part 11 and EHEDG guidelines for cleanability, preventing bacterial contamination in aseptic processing.
⚙️ Engineering Advantages
NACE Compliance for Sour Service: MR0175/ISO 15156 certification enables deployment in H₂S-containing environments (oil & gas production, refining) where sulfide stress cracking destroys non-compliant materials within months, ensuring safe operation in sour gas wells and crude processing units.
ATEX Intrinsic Safety: Ex ia IIC T6 approval for Zone 0/1 hazardous areas eliminates need for explosion-proof enclosures costing $2K-5K per installation, enabling direct mounting in classified locations with simple barrier installation in safe area marshalling cabinets.
Remote Seal Flexibility: Capillary lengths from 1-30 meters allow transmitter placement in accessible locations while diaphragm seals contact process media, reducing maintenance costs by 50% through elimination of scaffolding, hot work permits, and confined space entry for calibration and service.
9-Point Calibration Certificate: EN 10204-3.1 inspection certificate with NIST-traceable calibration data across full span ensures compliance with ISO 9001 quality systems, FDA validation requirements, and custody transfer accuracy standards in regulated industries.
