It outputs a HART digital signal superimposed on a 4-20 mA analog loop, with advanced functionality that supports remote configuration and diagnostics over the same two wires. The sensor span covers 2.67 to 160 kPa (10.7 to 642 in. H2O) with a base accuracy of 0.075%, which means this transmitter resolves small pressure changes across filters, heat exchangers, or level legs with enough precision for custody-transfer-adjacent metering. ## Wetted materials and seal construction Both diaphragm seals use Hastelloy C-276 diaphragms (HM code) with a serrated seal surface finish, mounted flush (F extension) on AISI 316 SS flanges rated ASME CL150 / 2 in. Capillaries are 3 m (10 ft) long, AISI 316L SS armoured, filled with silicone oil PMX 200 10 cSt — the armour protects against mechanical damage in plant walkways or cable trays. The low-pressure side uses a non-wetted AISI 316L ss diaphragm with silicone oil fill (NACE compliant), and the entire wetted path carries material traceability per EN 10204-3.1. ## Certification and documentation package ATEX Explosion Proof Ex d certification covers installation in Zone 1 gas groups — the housing is AISI 316L SS barrel version with M20 x 1.5 electrical connection. An inspection certificate EN 10204 3.1 of calibration (9-point) and a separate EN 10204-3.1 for process wetted parts material traceability ship with the transmitter. The integral LCD display with keypad provides local zero/span adjustment and diagnostic readout without opening the enclosure.","metaTitle":"266DRHHSRRRT1-E2L1B2I2N5C1H3 + S26RAHE1SFHM1AESNNN +","metaDescription":"ABB 266DRHHSRRRT1-E2L1B2I2N5C1H3 differential pressure transmitter with rotating flange diaphragm seal.
