Diaphragm seal with flange connection

for pressure gaugesprocesschemical

Pressure measurement is a critical task in industries where thermal processes are employed. A wide range of instruments, such as the Bourdon tube, are employed to perform this task and there are numerous instances when the pressure measurement becomes a tough task due to the influence of various factors on the procurement measuring instrument. This is when diaphragm seals become necessary. Diaphragm seals, sometimes called chemical seals, are employed in situations where it is necessary to isolate the pressure sensor from the process medium. Diaphragm seals are safety mechanisms created to keep potentially harmful process material away from pressure gauges, transmitters and switches. The pressure is applied to the flexible diaphragm instead of the pressure sensor's interface, and it is then hydraulically communicated to the instrument by the fill fluid. A diaphragm seal assembly will have no impact on the instrument's performance if it is placed and filled correctly. A diaphragm seal's function is to separate a pressure measurement device from the process media. It is frequently employed for the most challenging measuring operations. Examples of such difficult situations include: when the environment is extreme or when it is challenging to establish a process connection to the measuring equipment; when the media being measured is corrosive, thick, adhesive, or readily solidified; or, when the process isn't chemically appropriate with the instrument material. Properties Diaphragm seal systems can be made from various materials. The diaphragm seal is separating the pressure gauge from the medium.
