It ships with a digital LCD integral display and integrated keypad for local configuration and re-range without a handheld, and the output stage is HART plus 4-20 mA with advanced functionality — the comms path a controls integrator expects for remote re-range and asset management. ## Hazardous area rating and mounting Hazardous-area approval is ATEX Intrinsic Safety Ex ia, which is the rating that lets the transmitter sit directly on a process tap in a Zone 0/1 hazardous area without an additional flameproof enclosure. ## Lead time and sourcing posture Lead time on this build is listed at 8 - 10 weeks, so it lives on the quoted-to-order side of the storeroom rather than the fast-mover shelf — worth pulling into the min/max review before a planned outage. No cross-reference or pin-compatible alternative is recorded in this build's evidence, so any swap would require re-validating the wetted-parts code against the process line.","metaTitle":"ABB 266DSHMHKB1T1E1L1B2H1 Differential Pressure Transmitter","metaDescription":"ABB 266DSHMHKB1T1E1L1B2H1 266DSH differential pressure transmitter for high static pressure service, HART + 4-20 mA, ATEX Ex ia, LCD with keypad.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Differential Pressure Transmitters"],"specifications":{"title":"266DSHMHKB1T1E1L1B2H1","Weight":"6.5 Kg","Application":"H = Differential measurement at high static pressure (REMARK)","Product No.":"266DSHMHKB1T1E1L1B2H1","description":"266DSH Differential Pressure Transmitter","Integral LCD":"L1 = Digital LCD integral display with integrated keypad","Product Type":"266DSH Differential Pressure Transmitter","Shipping Weight":"8 Kg","lifecycle_stage":"current","Estimated Lead Time":"8 - 10 weeks.","SENSOR - Span limits":"M","Output/Additional options":"1 = HART and 4 to 20 mA - Advanced functionality (includes option R1)","Bolts/Gasket (wetted parts)":"1","Mounting bracket (shape and material)":"B2 = For pipe/wall mounting - AISI 316 L ss","Housing material and electrical connection":"T","Diaphragm material / Fill fluid (wetted parts)":"K","Process flanges/adapters material and connection (wetted parts)":"B","Hazardous area certifications (see relevant paragraph for complete detailed markings)":"E1 = ATEX Intrinsic Safety Ex ia"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1,594.00","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/d9b33f8b652873f00221c4f593781a2f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is 266DSHMHKB1T1E1L1B2H1 used for and what approvals does it carry?","answer":"It is a 266DSH differential pressure transmitter set up for differential measurement at high static pressure, with ATEX Intrinsic Safety Ex ia approval and a HART plus 4-20 mA output stage — the standard combination for a hazardous-area DP loop on a process line."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/abb/266DSHMHKB1T1E1L1B2H1","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/266DSHMHKB1T1E1L1B2H1 when reusing this data.
