They are available in various sizes and configurations, making them well suited for use in both low- and high-pressure environments. Diaphragm pressure gauges are also relatively low maintenance, making them a popular choice for many applications.
Features of diaphragm pressure gauge
A diaphragm pressure gauge is a type of pressure gauge that uses a Diaphragm to measure pressure. The diaphragm is a flexible membrane that deflects when pressurized fluid is applied.
This deflection is transmitted via the hydraulic fluid to a pointer, which then indicates the pressure on a dial. Diaphragm pressure gauges are used in many industries, including the oil and gas industry, where they are used to measure the pressure of liquids and gases.
They are also used in the medical industry, where they are used to measure blood pressure. Diaphragm pressure gauges are available in different sizes and with different ranges of pressures. Depending on the application, they can be fitted with different types of connections.
4. Stainless Steel Pressure Gauge
Stainless steel pressure gauges are one of the market’s most popular types of pressure gauges. Stainless steel is a durable material that can withstand high pressures, making it ideal for a pressure gauge.
Stainless steel also has a high corrosion resistance, making it an ideal choice for use in environments with a risk of corrosion. Stainless steel pressure gauges are available in a variety of designs and sizes, making it easy to find one that will suit your needs. Whether you need a gauge for home or industrial use, a stainless-steel pressure gauge is an excellent choice.
It is suitable for fire protection valves intended for installation in harsh environments such as chemical or petrochemical industries, power plants, mining, and offshore and onshore installations.
The core of the pressure gauge, resistant to impacts, vibrations, and pulsations, moves suspended from a spring, which gives it a long service life and precision in operation.
The case filled with liquid glycerin is suitable for high dynamic pressure pulsation or vibration, with excellent impact resistance. The gauge uses an impact and heat-resistant sight glass.
Features of Stainless-steel pressure gauges

6. Sanitary Pressure Gauge
These units are designed for homogenizers and are manufactured in accordance. The absence of gaps and the mirror finish of the parts guarantee the best hygiene. The process is connected to a special diaphragm seal built into the pressure gauge.
Instruments can be filled with liquid to reduce the effects of difficult operating conditions such as vibrations and pulsations.
Sanitary pressure gauges are used in food-grade machinery in food, beverage, pharmaceutical, biochemical, etc. The diaphragm membrane is open at the bottom, it is not easy to hide dirt, and there is no dead angle for cleaning.
The manufacturing processes in these industries require continuous pressure measurement and control. Sanitary processes use hygienic application instruments to keep the medium away from the measuring instrument.
The medium presses on the flexible metal diaphragm; this pressure causes the system fill fluid to rise towards the pressure gauge to provide a reading.
The membranes must be thin to be able to respond to these pressure changes. When exposed to regular use, the membranes are tough but can become damaged as a result of rough handling or pressure surges and overloads. If the damage causes the membrane to rupture, the system fill fluid will leak into the process medium. The results? Product contamination, batch loss, and production interruption.
