Radical type Pressure Gauge

Introduction:

A radical type pressure gauge, also known as a radial type pressure gauge, is a device used to measure the pressure of a fluid or gas in a system. It is called "radical" or "radial" due to the positioning of the pressure sensing mechanism.

The construction of a radical type pressure gauge typically consists of a circular dial face with a pointer and a bourdon tube. The bourdon tube is a curved, hollow metal tube that acts as the primary sensing element. One end of the tube is sealed and connected to the pressure source, while the other end is connected to a linkage mechanism that translates the movement of the tube into the motion of the pointer on the dial face.

When pressure is applied to the sealed end of the bourdon tube, it tends to straighten or unwind. This deformation causes the free end of the tube to move, which, in turn, rotates the linkage mechanism and moves the pointer on the dial face. The position of the pointer indicates the pressure being measured.

One advantage of the radical type pressure gauge is its compact and robust design, making it suitable for a wide range of applications. It can measure both low and high pressures accurately, depending on the specific gauge's range. Additionally, the dial face usually includes scale markings and units for easy reading and interpretation.

Radial pressure gauges are commonly used in industrial processes, HVAC systems, automotive applications, hydraulic systems, and various other settings where pressure monitoring is essential. They provide a visual representation of pressure changes, allowing operators to monitor and control the system accordingly.

It's important to note that while the radical type pressure gauge is widely used, other types of pressure gauges, such as digital or electronic variants, have gained popularity in recent years due to their enhanced accuracy, digital readouts, and additional features.
