the diaphragm used as the measurement of small diaphragm pressure senor .

we can produce kinds of diaphragm according to the clients ' requirement . it is used for 150 160 70 80 pressure gauge
the span up : 1000 times .
thickness : according to clients' requiry
the type of diaphragm : 0.1KPA-10KPA.

For measuring a certain corrosive, non-freezing or crystallization of a variety of fluid media pressure or negative pressure.
Corrosion resistance depends on the membrane material.
Structure principle
  Instrument from the measuring system (including the flange joint, corrugated diaphragm), the transmission indication institutions (including connecting rod, gear transmission, pointer and dial) and housing (including Case and Hood) and so on. Splash-proof enclosure for the instrument structure, has good tightness, it can protect its internal organs from contamination ingress.
  The role of instrument principle is based on elastic element (diaphragm on the measuring system) deformation. In the measured medium pressure, forcing the diaphragm to produce the corresponding elastic deformation - displacement, linkage group by transmission through the transmission and to enlarge the pointer fixed on the gear will be measured by the value on the dial instructions out.
