What the sensor range means for your loop
The 266DSHSPSB2S8V3E2L1B5I2 is a differential pressure transmitter covering a sensor span from 1.6 bar up to 160 bar (23.2 to 2320 psi), configured for gauge measurement. That range suits medium-to-high pressure process lines — think filter differentials across a strainer, level on a pressurized vessel, or flow across an orifice plate where the DP stays within that window. The 4-20 mA HART output carries SIL 2/3 certification per IEC 61508, so it can be wired directly into a safety instrumented function without an external isolator.
Wetted parts and housing — materials that matter for process compatibility
All wetted surfaces are AISI 316L stainless steel: diaphragm, process flanges (horizontal 1/2-14 NPT-f through adapter), drain/vent valves on the flange side bottom, and bolts/gasket. Fill fluid is silicone oil. The housing is also AISI 316L stainless steel in a barrel version with 1/2-14 NPT electrical connection, sealed to ATEX Ex db (flameproof) standard. If your process fluid is compatible with 316L and silicone oil, this transmitter is ready for direct mounting — no additional isolation required.
Local interface and configuration
An integral digital LCD with integrated keypad (option L1) provides local zero/span adjustment and diagnostics readout without a communicator. For remote configuration, the HART 4-20 mA loop supports standard HART commands — a handheld or DCS card can read the PV and change range points.
