The sensor span limits run from 1.6 kPa up to 160 kPa (16 to 1600 mbar, 6.4 to 642 inH2O), covering the range you expect for filter monitoring, level measurement on closed tanks, and flow measurement across orifice plates. The output stage delivers HART protocol on a 4-20 mA loop with advanced functionality — the digital LCD display and integrated keypad let you re-range and configure the transmitter in the field without a communicator. For a technician commissioning a loop, that means you set the 4 and 20 mA points directly at the transmitter face, then verify the loop current with a DMM at the marshalling cabinet. ## Wetted parts and process connection — 316L throughout All wetted surfaces are AISI 316L stainless steel: the diaphragm, the process flanges and adapters (horizontal connection, 1/4-18 NPT female direct), the drain/vent valves on the process axis, and the bolts and gaskets. The fill fluid is silicone oil. For a process engineer specifying this into a line carrying corrosive media or requiring cleanability, the 316L construction across the entire wetted path eliminates galvanic couple concerns at the flange face. The housing is aluminium alloy with a 1/2-14 NPT electrical connection, barrel version. The mounting bracket is AISI 316L stainless steel for pipe or wall mounting. The additional tag plate is stainless steel with laser printing — the tag data survives the same environment the transmitter sees. ## Hazardous area certification and sourcing posture The transmitter carries ATEX Explosion Proof Ex db certification, per the option code. That means it is certified for Zone 1 gas groups where an explosive atmosphere may occur during normal operation — the enclosure contains any internal explosion and prevents it propagating to the surrounding atmosphere. The lifecycle stage is current production; the estimated lead time from order is 4 to 6 weeks. No stock-holding claim; sourced per RFQ.","metaTitle":"ABB 266DSHHSSA2A1V1E2L1B2I2 Differential Pressure","metaDescription":"ABB 266DSH differential pressure transmitter, span 1.6-160 kPa, HART 4-20 mA, ATEX Ex db, AISI 316L wetted parts.
