NPT-f process connection, integral LCD.","salesMarkdown":"## What the order code actually configures The ABB 266DSHHSMA1B1L1C1H4 is the 266DSH Differential Pressure Transmitter ordered for differential measurement at standard static pressure (S), paired with HART and 4 to 20 mA output on the advanced-functionality firmware — the protocol stack that drops straight into a DCS or asset-management host without a separate gateway. Sensor span runs from 1.6 to 160 kPa (16 to 1600 mbar, 6.4 to 642 inH2O), which puts this build in the low-to-mid DP range — the workhorse span for filter ΔP, vessel level via DP on a wet leg, and small-bore flow-element differentials rather than very high static line pressures. ## Diaphragm, fill fluid, and process side The wetted diaphragm is Monel 400 with silicone-oil fill, listed NACE — a corrosion-resistant build for hydrocarbon, offshore, and mildly sour-service lines where 316L is marginal, and the silicone fill keeps the span stable across the typical process-temperature swing. Process flanges and adapters are AISI 316L stainless with a horizontal 1/4 in. – 18 NPT-f direct connection, and the bolt/gasket set is 316 ss with Viton — the standard static-pressure configuration for a horizontal impulse line on a separator or filter housing. ## Housing, display, and field-side hardware The housing is the aluminium-alloy barrel with an M20 x 1.5 (CM 20) conduit entry — the variant specified for WirelessHART installations where the barrel form factor routes cleanly into a pole- or pipe-mount antenna bracket. An integral digital LCD with integrated keypad is included on the front face, so commissioning, span re-range, and trim happen at the instrument without a handheld — useful on a crowded skid where bringing a 375 communicator out is the slow part of the loop check. ## Documentation the buyer receives The build ships with an EN 10204-3.1 inspection certificate covering a 9-point calibration, plus an EN 10204-2.2 test report on the pressure-bearing and process-wetted parts (gaskets excluded) — the paper pack a QA reviewer expects when a DP transmitter lands on a pressure-boundary BOM line. ## Sourcing and lead-time posture Lifecycle is recorded as current on the ABB 266DSH line, with an estimated 4–6 week lead time — the part is configured-to-order against the order-code string rather than pulled off a shelf, so quoting and confirmation run through an RFQ on this exact suffix.","metaTitle":"ABB 266DSHHSMA1B1L1C1H4 DP transmitter, 160 kPa","metaDescription":"ABB 266DSHHSMA1B1L1C1H4 differential pressure transmitter for standard static service, HART + 4–20 mA, Monel diaphragm.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Differential Pressure Transmitters"],"specifications":{"title":"266DSHHSMA1B1L1C1H4","Application":"S = Differential measurement at standard static pressure","Product No.":"266DSHHSMA1B1L1C1H4","description":"266DSH Differential Pressure Transmitter","Integral LCD":"L1 = Digital LCD integral display with integrated keypad (Note 19)","Product type":"266DSH Differential Pressure Transmitter","Shipping Weight":"6 Kg","lifecycle_stage":"current","Estimated Lead Time":"4 - 6 weeks.","SENSOR - Span limits":"H = 1.6 and 160 kPa, 16 and 1600 mbar, 6.4 and 642 inH2O.","Material traceability":"H4 = Test report EN 10204–2.2 of pressure bearing and process wetted parts (not for gaskets)","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®","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), (TO BE USED for WirelessHART)","Diaphragm material / Fill fluid (wetted parts)":"M = Monel 400, Silicone oil, (Notes 2, 17, 30) NACE","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":"$1,881.00","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/d9b33f8b652873f00221c4f593781a2f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is 266DSHHSMA1B1L1C1H4's listed application and product number on this line?","answer":"The application is S = differential measurement at standard static pressure, and the product number on the ABB 266DSH family is 266DSHHSMA1B1L1C1H4 — the suffix selects span range, diaphragm material, output protocol, housing, and documentation pack together."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/abb/266DSHHSMA1B1L1C1H4","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/266DSHHSMA1B1L1C1H4 when reusing this data.
