What the ABB 266HSH delivers in this build
The ABB 266HSHQSBA1-VAE2L1B7S2I2C6 is a gauge pressure transmitter in the 266HSH line, built for process-line pressure measurement with a base accuracy of 0.15 %, which sets the calibrated reference performance against which the loop is trimmed during commissioning. It is configured as a low-power-consumption gauge pressure transmitter with 1 to 5 V DC output and HART digital communication, so it can sit on a HART multidrop or a 4 to 20 mA loop where the 1 to 5 V variant is wired — the additional ordering-code slots in the code string carry the exact protocol and option mix.
Sensor envelope and hazardous-area rating
Sensor span limits are listed as 80 and 8000 kPa, which is 0.8 and 80 bar or 11.6 and 1160 psi — that is the full calibrated range window for the Q-span variant selected here, so the calibrated range and engineering units need to be confirmed against the site P&ID before power-up. Hazardous-area certification is: ATEX Explosion Proof Group II Category 1/2 G Ex d IIC T6 and Group II Category 1/2 D Ex tD A21 IP67 T85 °C, which means the housing is rated for flameproof service in gas groups up to IIC (hydrogen-class) and dust protection to IP67 at 85 °C surface temperature.
Wetted materials, housing, and electrical entry
Process connection is 1/2 in.-14 NPT female in AISI 316L stainless steel with NACE compliance, the diaphragm is AISI 316L SST (1.4435) with silicone oil fill, and the drain/vent valve is AISI 316L ss — all wetted parts meet NACE, which is the standard for sour-service (H2S-containing) process fluids. The housing is an aluminium-alloy barrel with a 1/2 in.-14 NPT electrical connection, so field wiring lands through a conduit entry rather than a cable gland — this matches the ATEX flameproof installation practice for the rated zone. The integral digital LCD (LI option) gives a local read at the transmitter without a handheld, useful during the commissioning walk-down when the HART master is still being connected.
Options that change the order code suffix
The code string carries the surge/transient protector (S2), a stainless-steel laser-printed tag plate (I2), and an EN 10204-2.1 certificate of compliance with the order (C6) — the surge option is the meaningful one for field installation where the loop runs outdoors or near VFD-driven motors and switching transients on the cabling are a real risk.
Sourcing posture for this build
The 266HSHQSBA1-VAE2L1B7S2I2C6 build is a configured ABB part — the listed lifecycle stage is current, with an estimated lead time of 8 to 12 weeks on the configuration as ordered, so it should be treated as a quoted-to-order build against the BOM rather than a shelf-pull.
