A diaphragm seal, also known as a pressure diaphragm seal or simply a seal, is a device used to protect pressure instruments, such as pressure gauges or transmitters, from the process media they are measuring. It consists of a thin diaphragm made of a flexible material, such as stainless steel or elastomers, which separates the process media from the internal components of the instrument.

​

The diaphragm seal is installed between the pressure instrument and the process media, acting as a barrier. It allows the pressure to be transmitted to the instrument while preventing direct contact with the process media, which may be corrosive, viscous, or contain solid particles. This protects the sensitive internal components of the instrument from damage or contamination.

​

Diaphragm seals are commonly used in industries such as chemical processing, oil and gas, pharmaceuticals, and food and beverage, where accurate pressure measurement is crucial. They enable pressure instruments to be used in challenging process conditions, extending their lifespan and ensuring reliable and accurate measurements.
