Hongqi 100mm Pressure Gauge with IP54 Protection A capsule pressure gauge is a type of mechanical pressure gauge used to measure pressure inside a system or container. It consists of a flexible diaphragm or capsule made of metal or plastic that expands or contracts in response to changes in pressure. The displacement of the capsule is then converted into a pressure reading through a system of levers, gears, or springs. Capsule pressure gauges are commonly used in low-pressure applications such as air conditioning and heating systems, pneumatic systems, and hydraulic systems. They are often chosen for their compact size, accuracy, and ability to withstand shock and vibration. A stainless steel pressure gauge is a device used to measure the pressure of fluids and gases in various industrial and mechanical applications. As the name suggests, this pressure gauge is made of stainless steel, which makes it durable, corrosion-resistant, and suitable for use in harsh environments.
These gauges come in different types, sizes, and pressure ranges to suit various applications. They can be used for measuring the pressure of liquids, gases, and steam in pipelines, tanks, and vessels.
The working principle of a stainless steel pressure gauge involves converting the applied pressure into mechanical movement, which is then displayed on a dial. The gauge consists of a bourdon tube, which is a curved tube made out of stainless steel. When pressure is applied to the tube, it tends to straighten out, which results in a corresponding movement of the dial needle.
Stainless steel pressure gauges are widely used in the oil and gas industry, chemical industries, pharmaceuticals, power plants, and many other applications where accurate pressure measurement is essential. They are reliable, long-lasting, and offer excellent performance under demanding conditions.
