Working PrincipleDiaphragm absolute pressure gauge is composing of inner cavity, outer cavity and movement. Inner cavityis a vacuum cavity, which is composing of diaphragm, upper parts and bellows vacuumize according to thedifferent ranges. Outer cavity is composing of diaphragm and lower parts; connect to atmosphere or vacuumpump by the socket. When outer cavity is vacuum (negative pressure), before vacuumize absolute pressure tothe upper limit, negative pressure of inner cavity is higher than outer cavityns. The pointer should on zero. Whenthe negative pressure of outer cavity is higher than inner cavityns, the diaphragm has down displacement, anddrive the movement teeth by transfer shank, the pointer has excursion, so can measure the absolute pressure.3. 1/T 100mm8 160a100 mmT-20 +60010/ 16/25/40/ 60/ 100 kPa abs1.6)V 10201.53.
