The order code decodes to a 316L SS barrel housing with M20 x 1.5 electrical connection, a 316L SS diaphragm filled with silicone oil, and a 1/2-14 NPT male process connection. The span limits cover 0.06 to 6 bar (0.87 to 87 psi), making it suitable for medium-pressure process monitoring on pumps, compressors, and filtration skids. Output is 4-20 mA with HART digital communication, and the integral LCD (L1 option) gives a local pressure readout without needing a handheld communicator. The S2 option adds a surge/transient protector on the loop — worth having if the transmitter sits on a long cable run or near motor starters where inductive kickback is a risk. ## Hazardous-area fit and wetted materials ATEX Intrinsic Safety certification (option) covers Gas Group IIC T6 and Dust Group II 1/2 D T95 °C. That means the transmitter can be installed in Zone 0 gas and Zone 20 dust atmospheres without a separate barrier if the loop is fed through a certified isolator. The 316L SS wetted parts — body, diaphragm, and drain/vent valve on process axis — handle most corrosive process fluids except strong chlorides above 60 °C. The carbon steel pipe/wall mounting bracket (B6) is explicitly marked as not suitable for AISI 316L housings — if the environment demands full stainless corrosion resistance, order the stainless bracket variant instead. The barrel housing itself is 316L SS, so the bracket is the weak link in a washdown zone.","metaTitle":"266HSHMSTT1E1L1B6S2I2 Gauge Pressure Transmitter, 4-20mA HAR","metaDescription":"266HSHMSTT1E1L1B6S2I2 gauge pressure transmitter, 4-20 mA HART output, ATEX Intrinsic Safety, 316L SS wetted parts, current production, available to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Gauge Pressure Transmitters"],"specifications":{"Model":"266HSH Gauge Pressure Transmitter","Surge":"S2 = Surge/Transient Protector","title":"266HSHMSTT1E1L1B6S2I2","description":"Gauge Pressure Transmitter","Integral LCD":"L1 = Digital LCD integral display","Shipping Weight":"6 Kg","lifecycle_stage":"current","Estimated Lead Time":"6 - 8 weeks.","SENSOR - Span limits":"M = 6 and 600 kPa, 0.06 and 6 bar, 0.87 and 87 psi","Output/Additional options":"1 = HART digital communication and 4 to 20 mA, Options requested by “Additional ordering code”","Dimensions (WxHxD), approx":"9.1 cm X 14.5cm X 11.3 cm","Hazardous area certifications":"E1 = ATEX Intrinsic Safety II 1 G and II 1/2 G Ex ia IIC T6; II 1 D Ex iaD 20 T 95 °C and II 1/2D Ex iaD 21 T95 °C","Process connection (wetted parts)":"T = AISI 316 L ss 1/2 – 14 NPT-f male","Mounting bracket (shape and material)":"B6 = For pipe/wall mounting - Carbon steel (Not suitable for AISI housing)","Housing material and electrical connection":"T = AISI 316 L ss ( barrel version) M20 x 1.5 (CM20)","Diaphragm material / Fill fluid (wetted parts)":"S = AISI 316 L ss, Silicone oil","Drain/vent valve (material and position) (wetted parts)":"E1 = AISI 316 L ss, on process axis"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2,091.00","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/28b276557e9b519d61ddb8070c9d4923.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the lead time for 266HSHMSTT1E1L1B6S2I2?","answer":"Estimated lead time is 6 to 8 weeks.
