Diaphragm Type Pressure Gauges A Comprehensive Guide The diaphragm type pressure gauge is a reliable and versatile tool used to measure pressure in a wide range of applications. It consists of a flexible diaphragm that deflects in response to changes in pressure, which is transferred to a sensing mechanism that converts the movement into an electrical signal. This article will provide a comprehensive guide to diaphragm type pressure gauges, including their working principle, types, features, advantages, and applications. Working Principle The working principle of a diaphragm type pressure gauge is based on the deflection of a flexible diaphragm under pressure. The diaphragm is typically made of stainless steel or aluminum and is mounted between two chambers. One chamber is connected to the process fluid, while the other is connected to the vacuum or reference pressure. As the pressure in the process fluid increases, it exerts force on the diaphragm, causing it to deflect. The deflection of the diaphragm is proportional to the pressure exerted on it, and this movement is transferred to a sensing mechanism that translates it into an electrical signal. Types There are several types of diaphragm type pressure gauges available, including 1. Differential pressure gauges These gauges measure the difference in pressure between two points. They are commonly used to measure liquid levels, flow rates, and filter efficiency. 2. Absolute pressure gauges These gauges measure the pressure relative to a vacuum. They are ideal for applications where there is a risk of air ingress or where a high level of purity is required. 3 3 3 3diaphragm type pressure gauge company. Gauge pressure gauges These gauges measure the pressure relative to atmospheric pressure. They are commonly used to measure air pressure, combustion pressures, and fluid pressures in open systems.
