Spanning from 6 kPa to 600 kPa (0.06 bar to 6 bar, 0.87 psi to 87 psi), one transmitter covers a wide turndown on the same body. The 4 to 20 mA analogue output stacks on top of HART for configuration and advanced diagnostics, with an additional ordering-code slot reserved for option R1 and the customer-defined add-ons. In a panel this lands on the differential-pressure transmitter segment of the rack, wired through the 1/2 in. NPT entry on the aluminium barrel housing. ## Wetted-parts stack and process-side footprint Wetted side is full stainless: AISI 316 L diaphragm, AISI 316 L flanges on a horizontal connection with 1/4 in. – 18 NPT-f direct process entries, and an AISI 316 L drain/vent valve on the process axis. The bolts and gasket set is sized for standard static, high static and gauge versions in AISI 316 ss with a PTFE gasket — meaning the same cell installs across standard DP and gauge-pressure mounting kits without a gasket change-out. Silicone oil fills the capillary, which is the standard general-service fluid on hydrocarbon-side processes; applications demanding a different fill (inert, oxygen-clean, high-temperature) sit in a different code letter on this family. ## Sourcing posture for an active ABB build Lifecycle is recorded as current, and lead time on a build of this configuration runs 6 to 8 weeks. No alternative order code sits in the ledger as a second source, so a BOM line keyed to 266DSHMSSA2A1V1E1L1I2 stays on this exact build unless the project explicitly opens a substitution review.","metaTitle":"ABB 266DSHMSSA2A1V1E1L1I2 Differential Pressure Transmitter","metaDescription":"ABB 266DSH differential pressure transmitter, 6–600 kPa span, 4–20 mA + HART, ATEX Ex ia, AISI 316L wetted parts.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Differential Pressure Transmitters"],"specifications":{"Model":"266DSH Differential Pressure Transmitter","title":"266DSHMSSA2A1V1E1L1I2","Application":"S = Differential measurement at standard static pressure","description":"266DSH Differential Pressure Transmitter","Shipping Weight":"9 Kg","lifecycle_stage":"current","Estimated Lead Time":"6 - 8 weeks.","SENSOR - Span limits":"M = 6 and 600 kPa, 0.06 and 6 bar, 0.87 and 87 psi","Output/Additional options":"1 = HART and 4 to 20 mA - Advanced functionality (includes option R1), Options requested by “Additional ordering code”","Dimensions (WxHxD), approx":"14.2 cm X 21 cm X 11.3 cm","Bolts/Gasket (wetted parts)":"2 = For standard static, high static and gauge versions, AISI 316 ss, PTFE","Hazardous area certifications":"E1 = ATEX Intrinsic Safety Ex ia","Housing material and electrical connection":"A = Aluminium alloy ( barrel version), 1/2 in. – 14 NPT","Diaphragm material / Fill fluid (wetted parts)":"S = AISI 316 L ss, Silicone oil","Drain/vent valve (material and position) (wetted parts)":"V1 = AISI 316 L ss, on process axis","Process flanges/adapters material and connection (wetted parts)":"A = AISI 316 L ss (Horizontal connection), 1/4 in. – 18 NPT-f direct"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1,841.00","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/551605a4a2718e0930eabca37e9fd96a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is 266DSHMSSA2A1V1E1L1I2 used for on this differential pressure line?","answer":"Application letter S in this build is standard differential measurement at standard static pressure, paired with the M sensor span of 6 to 600 kPa / 0.06 to 6 bar / 0.87 to 87 psi.
