Understanding Diaphragm Sealed Pressure Gauges A Focus on WIKA Instruments

In industrial applications, accurate pressure measurement is critical for ensuring the safety, efficiency, and reliability of operations. Among various types of pressure measurement instruments, diaphragm sealed pressure gauges have gained significant attention, particularly from a leading manufacturer like WIKA. This article explores the functionality and advantages of diaphragm sealed pressure gauges, specifically focusing on the offerings from WIKA.

What is a Diaphragm Sealed Pressure Gauge?

A diaphragm sealed pressure gauge is a specialized instrument designed to measure pressure in environments where the medium might be corrosive, viscous, or contains solid particles. The primary purpose of the diaphragm seal is to isolate the measuring instrument from the process medium to prevent damage or contamination. The diaphragm itself is a flexible barrier that moves in response to the pressure of the medium, transferring force to the pressure sensing element of the gauge without direct contact.

How Does a Diaphragm Pressure Gauge Work?

In a typical diaphragm pressure gauge, the diaphragm is installed in a housing filled with a compatible fill fluid. When pressure is applied to the diaphragm, it flexes and transmits that pressure to the fill fluid, which in turn moves the measuring element, typically a Bourdon tube or a pressure transducer. The gauge then converts this movement into a readable pressure value, which is displayed on the dial or through electronic means.

The use of a diaphragm ensures that only the fill fluid and the gauge mechanism come into contact, effectively protecting the gauge from the characteristics of harsh process conditions. This makes diaphragm sealed gauges particularly suitable for a range of industries, including chemical processing, food and beverage, pharmaceuticals, and oil and gas.
