The sensor span limits are 0.54 to 16 kPa (5.4 to 160 mbar, 2.16 to 64 inH2O), which sets the calibrated range for process measurement. All wetted parts — diaphragm, process flanges, drain/vent valves — are AISI 316L stainless steel, with silicone oil fill fluid. The bolts and gasket are stainless steel for the high static pressure version, rated to a maximum working pressure of 42 MPa. The output is HART 4-20 mA with advanced functionality, and the transmitter includes a digital LCD display with an integrated keypad for local configuration and readout. ## Hazardous area certification and mechanical build Certified ATEX Explosion Proof Ex db, this transmitter is suited for installation in Zone 1 or Zone 2 gas hazardous areas. The housing is aluminium alloy with a barrel-style M20 x 1.5 electrical connection. The mounting bracket is AISI 316L stainless steel for pipe or wall mounting. An inspection certificate per EN 10204-3.1 (9-point calibration) is included with the unit. The process connection uses horizontal AISI 316L flanges with 1/4 in. – 18 NPT-f direct connection. Drain/vent valves are AISI 316L, positioned on the flange side top, NACE compliant. Estimated lead time is 6 to 8 weeks.","metaTitle":"ABB 266DSHESSA4B1V2E2L1B2C1 Differential Pressure","metaDescription":"ABB 266DSHESSA4B1V2E2L1B2C1 differential pressure transmitter, span 0.54-16 kPa, HART 4-20 mA, ATEX Ex db, 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":"266DSHESSA4B1V2E2L1B2C1","Weight":"5 Kg","Application":"S = Differential measurement at standard static pressure","description":"266DSH Differential Pressure Transmitter","Integral LCD":"L1 = Digital LCD integral display with integrated keypad","Shipping Weight":"8Kg","lifecycle_stage":"current","Estimated Lead Time":"6 - 8 weeks.","SENSOR - Span limits":"E = 0.54 and 16 kPa, 5.4 and 160 mbar, 2.16 and 64 inH2O","Bolts/Gasket (wetted parts)":"4 = For high static version, Stainless steel – MWP = 42 MPa, PTFE","Mounting bracket (shape and material)":"B2 = For pipe/wall mounting - AISI 316 L ss","Certificates (multiple selection allowed)":"C1 = Inspection certificate EN 10204–3.1 of calibration (9-point)","Housing material and electrical connection":"B = Aluminium alloy ( barrel version) M20 x 1.5 (CM 20)","Output/Additional options - 13th character":"1 = HART and 4 to 20 mA - Advanced functionality (includes option R1","Diaphragm material / Fill fluid (wetted parts)":"S = AISI 316 L ss, Silicone oil","Drain/vent valve (material and position) (wetted parts)":"V2 = AISI 316 L ss on flange side top (Notes 7, 10, 17) NACE","Process flanges/adapters material and connection (wetted parts)":"A = AISI 316 L ss (Horizontal connection) 1/4 in. – 18 NPT-f direct","Hazardous area certifications (see relevant paragraph for complete detailed markings)":"E2 = ATEX Explosion Proof Ex db"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3,652.00","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/9873b4448073012c4df2d2f28a75cbc8.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy 266DSHESSA4B1V2E2L1B2C1 and how do I get a price?","answer":"Submit an RFQ to confirm current availability and pricing; the estimated lead time is 6 to 8 weeks."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/abb/266DSHESSA4B1V2E2L1B2C1","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/266DSHESSA4B1V2E2L1B2C1 when reusing this data.
