Ключевые параметры
Measuring range
Line sizes ½–12 in. (15–300 mm); 405C from 2 in.; DP limits by size/temp (e.g. ≤8 in. up to 1200 inH2O at ≤850 °F); max working pressure ASME B16.5 Class 600 / DIN PN100
Accuracy
405C discharge coefficient uncertainty ±1.00% (β=0.40/0.50/0.65; ±0.50% for β=0.40 with WD cal); 405P ±2.25% (½ in.), ±1.75% (1–1½ in.), ±1.25% (2–12 in.)
Output
N/A as primary element alone; pairs with Rosemount 3051/3051S/2051 transmitters (factory assemble → 3051CFC/3051SFC/2051CFC)
Process connection
Wafer/compact install between raised-face flanges; ANSI alignment ring for 10–12 in.; direct-mount 3-valve manifold or remote NPT
Wetted parts
316 SST primary element typical; beta options 0.40/0.50/0.65 (405C/P)
Media temperature
Direct mount −40 to 450 °F (−40 to 232 °C); remote mount −321 to 850 °F (−196 to 454 °C)
