Output is HART digital communication on a 4 to 20 mA loop, so you get the analog signal plus digital access to configuration and diagnostics over the same two wires. It ships with an integral LCD display for local read-back, and the S2 surge/transient protector is already built into the order code — one less external suppressor to panel-mount and wire. Wetted parts are AISI 316L stainless steel diaphragm with silicone oil fill, process connection is 1/2-14 NPT male, and the housing is a 316L SS barrel version with M20 x 1.5 electrical entry. ## Span limits and what they tell you Span limits run from 2.67 to 160 kPa (or 26.7 to 1600 mbar, 20 to 1200 mmHg). That means the transmitter is factory-configured within that range — you pick the calibrated span when you order. The lower end (2.67 kPa) suits low-differential vacuum service; the full 160 kPa covers moderate process pressures. If your application sits well outside these limits, this isn't the right sensor family. ## ATEX intrinsic safety — zone 0 and zone 1 Certified ATEX Intrinsic Safety II 1 G and II 1/2 G Ex ia IIC T6; also II 1 D Ex iaD 20 T 95 °C and II 1/2D Ex iaD 21 T95 °C. This covers gas groups up to IIC (hydrogen, acetylene) in Zone 0 or Zone 1, plus dust in Zone 20/21. The T6 temperature class (surface temp ≤ 85 °C) means it's safe in atmospheres with auto-ignition temperatures above 85 °C. No external zener barrier required if the loop is fed from a certified intrinsically safe supply — but verify the loop capacitance and inductance limits against the associated apparatus documentation.","metaTitle":"266NSHHSTT1E1L1B6S2I2 Absolute Pressure Transmitter, 0.075%","metaDescription":"Absolute Pressure Transmitter with 0.075% base accuracy, HART 4-20 mA output, ATEX Intrinsic Safety, integral LCD, surge protector.
