Diaphragm seals, also known as remote seals or chemical seals, basically have two tasks. Firstly, they separate the measuring device from the medium and secondly, they transfer the pressure to the measuring device and can be disassembled very easily and quickly for cleaning and calibration purposes.
They are typically used in application areas where the process medium should not come into contact with the pressurised parts of the measuring instrument. This protects the measuring instrument and extends its service life.
Sanitary diaphragm seals are used primarily in industries that require a high level of sanitation. For example, in the pharmaceutical and beverage industries as well as in the water purification industry. Sanitation-conscious manufacturers gain a high level of safety and efficiency by using WIKA measuring instruments that are equipped with sanitary diaphragm seals.To achieve the required degree of purity in these areas, high temperatures and various chemicals are used in sterile or sanitary facilities. A diaphragm seal is therefore required in this environment to protect the measuring device and helps to extend its service life.
How does a diaphragm seal work?
A diaphragm made of the appropriate material separates the medium to be measured from the measuring instrument. The internal space between the diaphragm and the pressure measuring instrument is completely filled with a system fill fluid. The proces ...
moreCan a diaphragm monitoring system also be repaired through WIKA Service?
Unfortunately, a diaphragm monitoring system cannot be repaired through WIKA Service. The reason for this is to protect the high-quality medium. A precise examination of the two adjacent diaphragms is technically so complex that, from an economic p ...
