Span limits and wetted materials define the fit
This ABB 266DSHESSA4B1V2E2L1B2C1 is a differential pressure transmitter from the 266DSH series, configured for differential measurement at standard static pressure. The sensor span limits are 0.54 to 16 kPa (5.4 to 160 mbar, 2.16 to 64 inH2O), which sets the calibrated range for process measurement. All wetted parts — diaphragm, process flanges, drain/vent valves — are AISI 316L stainless steel, with silicone oil fill fluid. The bolts and gasket are stainless steel for the high static pressure version, rated to a maximum working pressure of 42 MPa. The output is HART 4-20 mA with advanced functionality, and the transmitter includes a digital LCD display with an integrated keypad for local configuration and readout.
Hazardous area certification and mechanical build
Certified ATEX Explosion Proof Ex db, this transmitter is suited for installation in Zone 1 or Zone 2 gas hazardous areas. The housing is aluminium alloy with a barrel-style M20 x 1.5 electrical connection. The mounting bracket is AISI 316L stainless steel for pipe or wall mounting. An inspection certificate per EN 10204-3.1 (9-point calibration) is included with the unit. The process connection uses horizontal AISI 316L flanges with 1/4 in. – 18 NPT-f direct connection. Drain/vent valves are AISI 316L, positioned on the flange side top, NACE compliant.
Estimated lead time is 6 to 8 weeks.
