Diaphragm seals play an essential role in protecting various pressure instruments across a range of industries. The sensing elements of pressure gauges and switches need to be isolated from process fluids in many cases. Diaphragm seals are designed to seal enclosures within these delicate instruments, separating them from dangerous media.
These seals must also act to keep the process fluid from being affected by contact with the sensor. This is especially important in the food and beverage industry, where fluid accumulation can result in health concerns. The use of the right diaphragm seal prevents bacteria development over time. In other cases, the pressure sensor itself may cause metallic contamination of the process fluid; diaphragm seals stop this from occurring.
Common Diaphragm Seal Applications
A wide variety of seal types are available, to be used for a range of purposes. There are a number of common diaphragm seal applications to be aware of. They are frequently used with instruments in the oil and gas/chemical field. Complete process control and reliable monitoring is essential throughout the oil drilling, production, and refinement process, so taking great care of your pressure instruments is vital.
Likewise, energy companies require the use of a variety of instruments for generators, transformers, turbines, pumps, and more. The sensors used to monitor the pressure in the energy field should be protected with diaphragm seals. Other industries include:
Water and Waste Water
Transportation and Logistics
Machinery
Laboratory and Medical
Food and Beverage
About Diaphragms
Generally, diaphragms are made from metal, rubber, Teflon, plated metal, or other coatings. Diaphragms range from 0.002” to 0.008” in thickness. Their diameter is typically 5/8” of an inch or larger. They may be welded between two metal housings, welded to an upper housing, or clamped between two solid housings, depending on the type of diaphragm used.
It is important to bear in mind that the diaphragm and seal you use will reflect your specific application. Every industry has different requirements and distinct pressure instruments necessitate the use of different types of seals. Always ensure that the seal you use matches the specification situation. Don’t hesitate to reach out for assistance when attempting to make a determination in this regard. The experienced team at ESP would be happy to guide you every step of the way.
