What this order code builds
The 266HSHPSTT1E1L1B6S2I2 is a fully configured 266HSH gauge pressure transmitter from ABB Measurement & Analytics. The order code decodes to: gauge pressure (266HSH), span limits 0.24 to 24 bar (P), AISI 316L SS 1/2-14 NPT male process connection (T), AISI 316L SS barrel housing with M20x1.5 electrical connection (T), ATEX Intrinsic Safety certification, integral digital LCD display (L1), carbon steel pipe/wall mounting bracket (B6), surge/transient protector (S2), and HART digital communication with 4-20 mA output (1).
Span limits of 0.24 to 24 bar (3.5 to 348 psi) cover most industrial process lines — water, steam, compressed air, light chemical duty. The 4-20 mA HART output means it drops into any existing analog input card with HART capability; no separate power supply needed beyond the loop. The ATEX Intrinsic Safety rating (II 1 G Ex ia IIC T6) allows direct installation in Zone 0 gas areas and Zone 20 dust areas — a key spec for petrochemical, pharmaceutical, or gas-processing skids. The integral LCD (L1) gives local readout without a handheld terminal, handy for commissioning and spot checks.
Wetted parts and connections
All wetted parts — diaphragm and body — are AISI 316L stainless steel, with silicone oil fill. The 1/2-14 NPT male process connection is the standard for North American pipe threads; the M20x1.5 electrical entry matches common European cable glands. The carbon steel mounting bracket is for pipe or wall mounting — note it is not suitable for AISI 316L housings (galvanic corrosion risk), so if the environment demands full stainless, order the stainless bracket variant instead.
