That sub-kilopascal range suits low-differential services like filter monitoring, furnace draft, or clean-room pressure tracking where the process side sits near atmospheric. The output is HART and 4–20 mA, standard functionality — loop-powered, so the two-wire connection carries both power and the process variable. The integral digital LCD display (code LS) is selectable only with this output code, giving a local readout without a separate meter. ## Hastelloy C-276 wetted path for sour/caustic service All wetted parts that contact the process fluid are Hastelloy C-276: diaphragm, fill fluid (silicone oil), drain/vent valves on the process axis, and the horizontal 1/4 in. NPT-f process flanges/adapters. Hastelloy C-276 handles chlorides, sour gas (H2S), and reducing acids that would pit 316L stainless — this is the material choice for offshore, chemical, and refinery services where the process composition is aggressive. The bolts/gasket are AISI 316 stainless steel rated to 16 MPa MWP, with a Viton O-ring. Material traceability to EN 10204–3.1 is included (code H3), so the inspection certificate covers the wetted parts for the documentation package. ## Mounting, housing, and tag identification The housing is aluminium alloy barrel version with M20 x 1.5 electrical connection, intended for pipe or wall mounting via the AISI 316L stainless steel bracket (code). The additional tag plate (I2) is stainless steel with laser printing — the nameplate matches the PO traceability requirement for skid or panel documentation.","metaTitle":"ABB 266DSHAPKD3B7V4LSB2I2H3 Differential Pressure","metaDescription":"ABB 266DSH Differential Pressure Transmitter with gauge measurement (P), 0.05-1 kPa span, Hastelloy C-276 wetted parts, HART 4-20 mA output, integrated LCD.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Differential Pressure Transmitters"],"specifications":{"title":"266DSHAPKD3B7V4LSB2I2H3","Application":"P = Gauge measurement","Product No.":"266DSHAPKD3B7V4LSB2I2H3","description":"266DSH Differential Pressure Transmitter","Integral LCD":"LS = Integrated digital LCD display (ONLY SELECTABLE WITH OUTPUT CODE 7)","Product type":"266DSH Differential Pressure Transmitter","Shipping Weight":"8 Kg","lifecycle_stage":"current","Estimated Lead Time":"10 - 12 weeks.","Additional tag plate":"I2 =Tag and certification stainless steel plates and laser printing of tag","SENSOR - Span limits":"A = 0.05 and 1 kPa, 0.5 and 10 mbar, 0.2 and 4 inH2O","Material traceability":"H3 = Inspection certificate EN 10204–3.1 of process wetted parts (not for gaskets)","Output/Additional options":"7 = HART and 4 to 20 mA - Standard functionality","Bolts/Gasket (wetted parts)":"3 = For standard static, gauge and flange mounted versions, AISI 316 ss – MWP = 16 MPa Viton®","Mounting bracket (shape and material)":"B2 = For pipe/wall mounting - AISI 316 L ss","Housing material and electrical connection":"B = Aluminium alloy ( barrel version), M20 x 1.5 (CM 20), (TO BE USED for WirelessHART)","Diaphragm material / Fill fluid (wetted parts)":"K = Hastelloy® C-276, Silicone oil (Note 30)","Drain/vent valve (material and position) (wetted parts)":"V4 = Hastelloy® C-276 on process axis (","Process flanges/adapters material and connection (wetted parts)":"D = Hastelloy® C-276 (Horizontal connection), 1/4 in. – 18 NPT-f direct"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1,920.00","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/d9b33f8b652873f00221c4f593781a2f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is 266DSHAPKD3B7V4LSB2I2H3's listed application?","answer":"The application code is P, which means gauge measurement.
