The span limits run from 6 to 600 kPa (0.06 to 6 bar, 0.87 to 87 psi) — that covers most low-to-mid pressure applications in water, steam, gas, and chemical lines. The output is HART and 4 to 20 mA with advanced functionality, so it fits right into existing 4-20 mA loops with HART handheld or DCS configuration. The wetted parts — process connection in AISI 316L stainless steel, 1/2-14 NPT male, and diaphragm also 316L with silicone oil fill — are NACE compliant, which matters when you're specifying for sour service or corrosive media. Housing is aluminium alloy, barrel version, with M20 x 1.5 electrical connection, intended for the WirelessHART option but works with standard cable glands too. ## Deployment context Mounts directly to a process pipe or vessel via the 1/2-14 NPT male connection — no bracket needed for most installations. The aluminium housing with M20 x 1.5 entry accepts standard cable glands; the barrel form factor fits where compact side-entry is required. Rated for industrial environments with the aluminium enclosure; no IP rating stated in the spec, but the housing material and NPT seal suggest typical weatherproof or light washdown areas — not submersible.","metaTitle":"266HSHMSTB1 Gauge Pressure Transmitter, HART 4-20 mA, 6-600","metaDescription":"266HSHMSTB1 266HSH gauge pressure transmitter, current lifecycle, HART 4-20 mA output, span 6-600 kPa, AISI 316L wetted parts.
