Understanding Bellows Differential Pressure Gauges A Comprehensive Overview

In industrial applications, precise measurement of pressure differential is crucial for ensuring the safety and efficiency of various processes. One of the most reliable tools for this purpose is the bellows differential pressure gauge. This article explores the workings, advantages, and applications of this vital instrument, along with some market insights.

What is a Bellows Differential Pressure Gauge?

A bellows differential pressure gauge is a device used to measure the difference in pressure between two points in a system. It employs a flexible bellows element that expands or contracts in response to changes in pressure. The mechanical movement of the bellows is transmitted to a dial or digital readout, providing a clear indication of the pressure differential.

The basic structure of a bellows differential pressure gauge includes a pair of bellows connected to two separate pressure sources. As the pressure in one source increases relative to the other, the bellows will either expand or contract. This movement turns a calibrated mechanism that displays the pressure difference on the gauge's face.

Advantages of Bellows Differential Pressure Gauges
