Approval code is ATEX Intrinsic Safety Ex ia — the loop must be fed from a certified IS barrier or segment coupler, and entity parameters on the barrier match the 266DSHESKA2T1E1L1B2H1 nameplate before commissioning, especially in a hydrocarbon or solvent-vapor service where a non-IS swap is a real liability. ## Build codes and what they pin down Diaphragm/fill fluid code K and process-flange/adapter code A fix the wetted side — when a storekeeper pulls this from the shelf, K and A on the nameplate are what verify it is the same wetted build the original PO authorized, and what rules out a drop-in alternate from a different cell in the 266 family. ## Lead time and shelf posture ABB lists this build as current production with an 8 to 10 week factory lead time, so it is a quoted-to-order part rather than a shelf-sitter — the right MRO call is to keep it on the BOM reorder line and trigger a min/max release before the eight-week mark, not to wait for a line-down.","metaTitle":"ABB 266DSHESKA2T1E1L1B2H1 Differential Pressure Transmitter","metaDescription":"ABB 266DSHESKA2T1E1L1B2H1 differential pressure transmitter, HART + 4-20 mA, ATEX Ex ia, integral LCD, AISI 316L bracket.
