The ATEX Intrinsic Safety certification (: 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) confirms it for Zone 0/1 gas and Zone 20/21 dust atmospheres, per IEC 60079-14 installation rules. The 4-20 mA output with HART digital communication allows remote configuration and diagnostics over a standard twisted pair — essential for offshore or refinery loops where loop-powered devices must pass through a safety barrier. ## Flange, Diaphragm, and Fill Fluid — What the Specs Mean for Fit The mounting flange is ASME CL 2500 / 2 in. — a 2500-pound class ring-joint flange for extreme pressures. The diaphragm material is Inconel 625, selected for corrosion resistance in sour-gas or chloride-laden environments. Fill fluid is silicone oil DC200 10 cSt, a standard high-temperature fill. The capillary length is 3 m (10 ft) with AISI 316L stainless steel armour protecting the capillary bundle from mechanical damage. The flush diaphragm with ring-joint seal surface finish eliminates dead-leg cavities — important for polymerizing, viscous, or sanitary media where a conventional impulse line would plug. ## Integral Display and Material Traceability The L1 option adds a digital LCD integral display for local pressure readout and HART loop diagnostics — useful during commissioning when the DCS is not yet live. Material traceability per EN 10204–2.1 is included for the process-wetted parts, satisfying the documentation requirements of NACE MR0175 / ISO 15156 applications.","metaTitle":"266HRHSRRB1E1L1B6H1 + S26RRHE6SFLM3AESNNN Gauge Pressure Tra","metaDescription":"Gauge pressure transmitter with remote seal, rotating flange diaphragm seal, ATEX Intrinsic Safety Ex ia IIC T6, 4-20 mA HART, Inconel 625 diaphragm, ASME CL 2500.
