Famous Pressure Gauges with Diaphragm Seals Ensuring Accurate Measurements in Tough Environments

Pressure measurement is a fundamental aspect of various industrial applications, where accuracy and reliability are paramount. Among the many technologies available for pressure measurement, pressure gauges with diaphragm seals stand out due to their ability to provide accurate readings, especially in harsh environments. This article examines some of the famous pressure gauges that utilize diaphragm seals, exploring their advantages, applications, and notable manufacturers.

Understanding Diaphragm Seals

Diaphragm seals are devices that isolate the pressure sensing element of a gauge from the process fluid. The seal consists of a flexible diaphragm made from materials like stainless steel, PTFE, or elastomers, which deforms under pressure. This deformation translates the process pressure to the sensing element, minimizing contamination and protecting it from corrosive, viscous, or high-temperature fluids.

The primary benefits of using diaphragm seals include the protection of the pressure sensing element, enhanced measurement accuracy, and extended service life of the gauge. They are particularly useful in industries such as chemical processing, oil and gas, food and beverage, and pharmaceuticals, where process conditions can be extreme.
