Pressure monitoring and control are essential to the reliable operation of firefighting water systems. Two components used for this purpose are the low-pressure switch and the electric-contact pressure gauge. Both respond to changes in system pressure and can be used to trigger control actions at preset pressure thresholds. In some applications, they may serve similar functions, but they differ in how they detect pressure changes, indicate pressure readings, and interact with control circuits.

The pressure gauge we usually refer to is an instrument that uses elastic elements as sensitive elements to measure and indicate pressure higher than the environment. It has a wide range of applications. Almost all modern industrial processes and scientific research fields use pressure gauges, such as heat pipe network, oil and gas transmission, water and gas supply systems, and street vehicle maintenance stores that we see every day. Pressure gauges can be seen everywhere. Speaking of this, you may not know much about the working principle and structure of the pressure gauge, right? Today, let's learn about the working principle of the pressure gauge and other details. 

In the 21st century and even in the future, it is an inevitable trend for enterprises to implement advanced automation, and instruments and meters will be indispensable for the operation of equipment. Pressure gauges refer to instruments that use elastic components as sensitive components to measure and indicate pressure higher than the environment. Since the main body is mostly made of stainless steel and has strong sealing performance, it has strong corrosion resistance, which undoubtedly expands the scope of use in the industrial field. Therefore, it is essential to understand the specific application range of the pressure gauge. Today let's learn the application and structural knowledge of pressure gauges.
