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.
What is a diaphragm seal?
A diaphragm seal is an additional component which protects a pressure measuring instrument or process transmitter. It transfers the medium to the measuring instrument without it coming into contact with the measuring instrument.
What are the mounting options for a diaphragm seal?
A diaphragm seal can be mounted via a direct connection, a cooling element or a capillary.
