Reliable E+H PMP71-2EWR7/101 pressure transmitter. Accuracy holds at ±0.05% even with frequent temperature swings. HART integration was smooth, setup took 10 mins via local displayEndress+Hauser. Wetted parts (316L/C276) handle corrosive media well, no drift so far. Good value for critical process loops.
