What is Diaphragm Seal?
The diaphragm seal system consists of Pressure Instruments, Fill fluid, and Diaphragm seal direct mounting type or capillary type.
In the process a flexible diaphragm and filling fluid separate the pressure instruments from process media, temperature, or service.
When process pressure acts on the diaphragm, diaphragm displacement transfers the measured pressure through the filling system. This transferred pressure displaces the pressure sensing element of Pressure Instruments.
A diaphragm seal is used to seal and safeguard instruments from the process medium. The flexibility of the seal is as such that, the diaphragm, seals the contents safely at same time permeating the instrument to measure the pressure accurately.
Diaphragm seals are in general use with other devices and instruments including pressure gauges, transmitters and switches. This combination can be used in extreme and harsh environmental conditions. The fact that they can isolate instruments from any kind of toxic and reactive chemical makes them an especially useful device.
Application of Diaphragm Seals
The application range of diaphragm seals is wide. The use of diaphragm seals in pressure gauges is to protect the sensing element from toxic and hazardous chemicals. Diaphragm seals are manufactured for use in extreme conditions, suitable for different industrial processes.
For instance, they are used with pressure gauges that are generally subjected to difficult process environments. They are used to protect the instrument from dangerous and corrosive media. In a way, diaphragm seals are used to enhance the lifetime of any instrument by protecting them against harmful media which can be at high temperature, highly corrosive in nature, vicious, and with highly toxic chemical combinations.
Types of Diaphragm Seals
Diaphragm seals are available for a variety of applications. Based on application, diaphragm seals can be categorized into:
- Inline Diaphragm Seal
These diaphragm seals are used to permit fluid flow and are inserted inside various connector types. The arrangement of the seals prevents process clogging or the gradual growth of any bacteria in the diaphragm.
- Threaded Diaphragm Seals
Designed to mount directly on threaded process connections, and threaded diaphragm seals. To work with gauges in switches and transmitters, these seals are connected via flexible and threaded capillaries. They are very small in size and are made to fit in tiny spaces.
- Diaphragm Seals with Flanges
Flanged diaphragm seals can be clamped between the process and covering flanges or are designed for direct mounting on the process counter flange. These seals are made to be mounted on gauges and transmitters and are offered in all international flange standards, including ASME EN, BS, API, ISO, or JIS. There are flanged diaphragm seals with flushing connections available.
- Sanitary Diaphragm Seals
Sanitary diaphragm seals are created especially for the food and pharmaceutical industries, where it is important to stop the growth of bacteria. Through the use of threaded or quick clamp couplings, these seals allow for simple cleaning. These seals comply with FDA regulations and prevent the growth of any bacteria.
Advantages of Diaphragm Seals:
Diaphragm seals guarantee that the results produced by the instrument are extremely accurate in addition to providing protection. To extend the life of instruments, diaphragm seals are installed, which over time saves both time and money.
The ability to adapt the mounting of these seals to the application is another key benefit. They are dependable tools that can be used in a variety of applications because they are built to meet industry standards.
Diaphragm seals have developed a reputation as tools that increase device longevity and reduce the cost of replacing a broken device.
