It is a 266DSH series differential pressure transmitter wired for differential measurement at standard static pressure (S), with sensor span limits from 0.24 to 24 bar — that range covers the typical hydrostatic, filter, and level-by-differential-pressure services on a process skid. ## Sensor span and the dP services it actually fits The span limits sit at 0.24 and 24 bar with 3.5 to 348 psi equivalent, so the same platform handles a tight clean-room filter ΔP and a mid-range separator level service without re-ranging hardware — only the sensor trim and the HART configuration change between applications. Output is HART plus 4 to 20 mA with advanced functionality (1), which includes the R1 option set — that gives the loop configurable damping, flow linearisation, and remote re-range via a handheld or asset-management system, removing the need for a local span screw. ## Wetted parts and process-side construction The diaphragm is AISI 316L stainless steel with silicone oil fill (S) and the process flanges/adapters are AISI 316L ss on a horizontal 1/2 in. – 14 NPT-f connection through adapter (B) — 316L with silicone fill is the default selection for hydrocarbon, water, and most chemical services; the horizontal connection simplifies impulse piping on a pipe stand. Bolts and gasket are AISI 316 ss with Viton® for standard, high-static, and gauge versions (1) — Viton limits the chemical compatibility envelope, so anything beyond hydrocarbons and mild chemicals needs a review against the process media before sign-off. ## Housing, display, and field wiring The housing is aluminium alloy in the barrel form with a 1/2 in. – 14 NPT electrical entry (A) — the barrel geometry fits the standard pipe/wall mounting bracket in carbon steel (, not suitable for AISI housings), giving a fixed pipe-stand or wall-mount installation without an extra adaptor plate. A digital LCD with integrated keypad is fitted locally, which lets the field tech configure tags, units, and damping without a handheld communicator during commissioning and loop checks. ## Sourcing and lead-time reality The model carries a current lifecycle stage with an estimated lead time of 8 to 10 weeks — a long factory lead time on a hazardous-area instrument means the MRO bin needs a strategic spare if a single failure can take a process unit off-line, and the BOM position should be flagged at quote time rather than at PO time. Independent distribution quotes the 266DSHPSSB1A1E1L1B1 to order against the BOM; current pricing and availability are confirmed against an RFQ, with full traceability on the Ex marking and wetted-parts certificate at shipment.","metaTitle":"ABB 266DSHPSSB1A1E1L1B1 Differential Pressure Transmitter","metaDescription":"ABB 266DSHPSSB1A1E1L1B1 differential pressure transmitter, 0.24–24 bar span, HART/4–20 mA, ATEX Ex ia, AISI 316L wetted.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Differential Pressure Transmitters"],"specifications":{"title":"266DSHPSSB1A1E1L1B1","Application":"S = Differential measurement at standard static pressure","Product No.":"266DSHPSSB1A1E1L1B1","description":"266DSH Differential Pressure Transmitter","Integral LCD":"L1 = Digital LCD integral display with integrated keypad","Product type":"266DSH Differential Pressure Transmitter","Shipping Weight":"5 Kg","lifecycle_stage":"current","Estimated Lead Time":"8 - 10 weeks.","SENSOR - Span limits":"P = 24 and 2400 kPa, 0.24 and 24 bar, 3.5 and 348 psi","Output/Additional options":"1 = HART and 4 to 20 mA - Advanced functionality (includes option R1)","Bolts/Gasket (wetted parts)":"1 = For standard static, high static and gauge versions, AISI 316 ss, Viton®","Hazardous area certifications":"E1 = ATEX Intrinsic Safety Ex ia","Mounting bracket (shape and material)":"B1 = For pipe/wall mounting - Carbon steel (Not suitable for AISI housing)","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","Process flanges/adapters material and connection (wetted parts)":"B = AISI 316 L ss (Horizontal connection), 1/2 in. – 14 NPT-f through adapter"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1,791.00","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/d9b33f8b652873f00221c4f593781a2f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the 266DSHPSSB1A1E1L1B1 used for?","answer":"It is built for differential measurement at standard static pressure, with sensor span limits from 0.24 to 24 bar — that covers clean-room and process filter ΔP, separator and vessel level by dP, and flow measurement across an orifice in the low-to-mid pressure range."},{"question":"Is 266DSHPSSB1A1E1L1B1 rated for Zone 1 hazardous areas?","answer":"It carries ATEX Intrinsic Safety Ex ia marking, so it is approved for Zone 1 installations when wired through a certified intrinsically-safe barrier — confirm the barrier entity parameters match the loop design before commissioning."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/abb/266DSHPSSB1A1E1L1B1","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/abb/266DSHPSSB1A1E1L1B1 when reusing this data.
