What this transmitter brings to a process line
The 266MSTFCSB3B1E1L1B1C1M5 is a differential pressure transmitter from ABB's 266MST series, delivering a 4 to 20 mA output with HART digital communication — so the loop carries both the analog process variable and digital diagnostics to a DCS or PLC without extra wiring. Sensor span limits run from 0.4 kPa up to 40 kPa (4 to 400 mbar), and the maximum working pressure hits 16 MPa / 160 bar / 2320 psi — sized for medium-differential applications like filter monitoring, flow measurement across an orifice plate, or level on a pressurized vessel. The integral LCD display (code L1) gives a local readout for commissioning and spot checks without needing a handheld communicator.
Materials and certifications for hazardous-area and oxygen service
Explosion protection is ATEX Intrinsic Safety Ex ia (code), so this unit can be wired into a Zone 0 or Zone 1 loop with an appropriate barrier — no flameproof enclosure needed. Diaphragm material is AISI 316L SST (1.4435) with silicone oil fill, NACE compliant for sour-gas environments. Bolts are AISI 316 SST (NACE, not exposed to H2S), and the gaskets are Viton — explicitly suitable for oxygen applications, though the max pressure on the gasket side is 41 MPa / 410 bar / 5945 psi. Process flanges and adapters are AISI 316L SST (1.4404 / 1.4408) with 1/2 in –14 NPT female through adapter, horizontal connection. Housing is aluminum alloy barrel type with M20 x 1.5 electrical connection. An inspection certificate 3.1 per EN 10204 of calibration ships with the unit — that's the mill-test-report-level traceability that quality-doc control wants for a FAT package.
Estimated lead time from the factory runs 10 to 12 weeks.
