The 266HDH platform is rated at 0.06 % base accuracy, which is the reference figure against which span, zero, and total error are trimmed at the factory — adequate for custody-class and tight-loop control on vessels, lines, and filter housings. ## Process side: direct-mount seal and wetted materials The seal side is configured as a direct-mount flush diaphragm with the high-pressure side on the transmitter side of the connection, and the seal itself follows EN 1092-1 on a PN 16-40 / DN 50 flange — meaning the transmitter bolts straight onto the process tapping without a capillary, which removes the temperature-induced zero shift that a long capillary would introduce. Wetted parts are AISI 316 L ss with silicone oil PMX 200 10 cSt as the fill fluid, so the diaphragm and fill are compatible with most water, steam, chemical, and hygienic lines that the 316 L / silicone pairing is specified against. ## Housing, conduit, and local readout The electronics housing is the aluminium alloy barrel version with an M20 x 1.5 (CM 20) electrical entry, so conduit or cable gland selection on site is sized to the M20 thread and the housing itself provides the environmental and EMC enclosure. A digital LCD integral display is fitted, giving local pressure readout at the transmitter without needing a handheld terminal for verification during walk-around checks.","metaTitle":"266HDHFRMB1L1 + S26REHN2SFSM1N1SNNN ABB","metaDescription":"ABB 266HDHFRMB1L1 + S26REHN2SFSM1N1SNNN gauge pressure transmitter with direct-mount S26 seal, 0.06% base accuracy, AISI 316L diaphragm, integral LCD.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Gauge Pressure Transmitters"],"specifications":{"1":"Capillary Length m (Feet) = Direct-mount construction","B":"Housing material and electrical connectionAluminium alloy ( barrel version)M20 x 1.5 (CM 20)","F":"Extensions Length and Material = Flush","H":"High pressure side = Transmitter Side of Connection","M":"Process connection (wetted parts) = Direct mount seal (one seal to be quoted separately)","N":"Flushing Ring: Plug and Gasket = No plug - No gasket","R":"Diaphragm material / Fill fluid - AISI 316 L ss, Silicone oil","S":"Fill Fluid = Silicone oil PMX 200 10 cSt","L1":"Integral LCD = Digital LCD integral display","N2":"Mounting Flange Rating / Size = PN 16 - 40 / DN 50","SM":"Diaphragm Material = AISI 316 L ss","S26RE":"Rotating flange diaphragm seal (flush and extended) to EN 1092-1","title":"266HDHFRMB1L1 + S26REHN2SFSM1N1SNNN","266HDH":"Gauge Pressure Transmitter with direct mount seal – BASE ACCURACY 0.06 %","Weight":"3 Kg","Product No.":"266HDHFRMB1L1 + S26REHN2SFSM1N1SNNN","description":"Gauge Pressure Transmitter + Model S26 seals for remote and direct mount","Product Type":"Gauge Pressure Transmitter + Model S26 seals for remote and direct mount","266HDHFRMB1L1":"Gauge Pressure Transmitter","Shipping Weight":"18 Kg","lifecycle_stage":"current","Estimated Lead Time":"8 - 10 weeks.","S26REHN2SFSM1N1SNNN":"Model S26 seals for remote and direct mount"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1,476.00","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/b0dca33f964f532a7a4b9378e1e89c0a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How is the 266HDHFRMB1L1 + S26REHN2SFSM1N1SNNN supplied for a volume build?","answer":"Volume builds are quoted to order against the RFQ quantity, not pulled from shelf stock — ABB's configured transmitter-and-seal combinations are built to the option string, and the typical acknowledgement window for a configured 266-series assembly is eight to ten weeks."},{"question":"What wetted materials does the 266HDHFRMB1L1 + S26REHN2SFSM1N1SNNN use on the process side?","answer":"The diaphragm is AISI 316 L stainless steel and the fill fluid is silicone oil PMX 200 10 cSt, with the seal configured as a direct-mount flush design on a PN 16-40 / DN 50 flange to EN 1092-1."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/abb/266HDHFRMB1L1-~3-S26REHN2SFSM1N1SNNN","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/266HDHFRMB1L1-~3-S26REHN2SFSM1N1SNNN when reusing this data.
