It outputs a HART and 4 to 20 mA signal with advanced functionality, including option R1. The sensor span limits are 0.06 to 6 bar (6 to 600 kPa), which covers a wide range of flow, level, and pressure-drop applications in process lines. ## Wetted parts and process connection Wetted parts are AISI 316L SS diaphragm with silicone oil fill, and AISI 316L SS process flanges with a 1/2 in. – 14 NPT-f horizontal connection through an adapter. Bolts and gasket are AISI 316 SS with PTFE, NACE compliant for non-exposed wetted parts. This combination handles standard static pressure ranges without corrosion concerns on common process fluids. The estimated lead time from the manufacturer is 6 to 8 weeks.","metaTitle":"266DSHMSSB2B1 Differential Pressure Transmitter, HART, 600 k","metaDescription":"266DSHMSSB2B1 differential pressure transmitter by ABB.
