The order code decodes to a sensor with span limits of 1.6 to 160 bar (160 to 16000 kPa, or 23.2 to 2320 psi), meaning you calibrate it within that range for your specific process pressure. Output is HART with 4-20 mA and advanced functionality (option 1). Wetted parts — process connection, diaphragm — are AISI 316L stainless steel, with silicone oil fill and NACE compliance for sour-service environments. The housing is aluminium alloy, barrel-style, with M20 x 1.5 electrical entry (option B). ## Materials and compliance considerations The 1/2-inch 14 NPT male process connection in AISI 316L SS, combined with the 316L diaphragm and NACE compliance (option T), makes this transmitter suited for corrosive or sour-gas media where hydrogen embrittlement is a risk. The silicone oil fill is standard for general-purpose pressure measurement; if oxygen service or high-temperature fill is needed, that would be a different option code. The aluminium housing with M20 cable entry is the barrel version, typically used where the transmitter mounts directly to the process pipe or manifold without a remote diaphragm seal.","metaTitle":"266HSHSSTB1 Gauge Pressure Transmitter, HART 4-20 mA, 160 ba","metaDescription":"266HSHSSTB1 gauge pressure transmitter by ABB.
