H2O) and a base accuracy of 0.06%, the figure that decides how tightly it holds a flow, level, or filter-differential reading against the loop reference. That 0.06% base accuracy is the headline number for any DP application — it is what sets the loop's calibration budget on a Venturi, orifice plate, or dp cell, and it is the spec a DCS engineer cross-checks against the flow computer's claimed uncertainty before sign-off. ## Wetted parts and process connection The wetted side is AISI 316L stainless with silicone oil fill (NACE compliant), PTFE gaskets, and AISI 316 bolts — a standard refinery/utility configuration that handles hydrocarbons, steam condensate, and treated water without needing an exotic upgrade. Process flanges and adapters are AISI 316L with 1/4 in.-18 NPT female direct-mount connections on the horizontal axis, and the vent/drain valves are 316L positioned on the process axis (NACE) — so the manifold stack lines up cleanly without forcing a 90° adapter on site. ## Housing, display, and panel-side wiring A digital LCD integral display with integrated keypad is fitted (option), so loop commissioning, ranging, and HART reconfiguration can be done at the instrument without a handheld communicator — useful on a hot platform or a confined boiler-house gallery. A carbon-steel pipe-mounting bracket is included (option), so the body bolts straight to a 2 in. standpipe without a separate saddle fabrication. ## Static pressure and tag-plate options Static pressure class is the standard rating (option S), which covers the typical line pressures seen on utility steam, condensate, and HVAC differential work — no high-static upgrade required for that envelope. Option I2 adds stainless-steel tag and certification plates with laser printing, which is the configuration most plant owners specify for traceable instrument registers and audit-friendly documentation packs. ## Sourcing and lead time The 266DSHHSSA2A1V1L1B1I2 is a current-production configuration of the ABB 2600T family, with ABB-listed availability flowing on a 6-8 week quoted lead time for build-to-order units — meaning the BOM line should be planned against that window rather than treated as shelf stock.","metaTitle":"ABB 266DSHHSSA2A1V1L1B1I2 DP Transmitter, 0.06% accuracy","metaDescription":"ABB 266DSHHSSA2A1V1L1B1I2 differential pressure transmitter, 0.06% base accuracy, HART + 4-20 mA, AISI 316L wetted, quoted to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Differential Pressure Transmitters"],"specifications":{"title":"266DSHHSSA2A1V1L1B1I2","Output":"1 : HART and 4 to 20 mA - Advanced functionality","description":"Differential Pressure Transmitter","Integral LCD":"L1 : Digital LCD integral display with integrated keypad","Shipping Weight":"3.5 Kg","lifecycle_stage":"current","Estimated Lead Time":"6-8 Weeks","Additional Tag Plate":"I2 : Tag and certification stainless steel plates and laser printing of tag","Span Limits / Base Accuracy":"H : 1.6 and 160 kPa (16 and 1600 mbar, 6.4 and 642 in.
