Pressure gauges for steam and boiler systems are specialized devices used to measure and display the pressure levels within steam boilers and associated piping systems.
They are installed at strategic locations throughout the steam and boiler system, providing visibility into pressure conditions at critical points. So, we can say they play a crucial role in monitoring the pressure conditions in boiler and steam systems, ensuring safe operation and optimal performance.
Stainless steel pressure gauges usually have a robust construction to withstand the high temperatures and pressures, which are common in steam and boiler applications. They should be accompanied by a pigtail syphon to protect the pressure gauge from the high media temperature.

They come in various types and mounting configurations to suit different applications, and are essential for maintaining optimal water pressure levels, but also for detecting leaks, diagnosing system issues, and ensuring efficient operation in residential, commercial, and industrial settings.
A pool filter pressure gauge is a device used to measure the pressure inside a pool's filtration system.
It helps assess the condition of the filter media by indicating how clogged or dirty it has become over time due to trapped debris and contaminants.
Typically, they are installed on the filter tank or valve, pool filter pressure gauges are designed to withstand exposure to all pool chemicals.
They provide a reading (usually in pounds per square inch (psi), which informs pool owners when it's time to clean or backwash the filter for optimal filtration efficiency.
Regular monitoring of the pressure gauge is crucial for proper pool maintenance, ensuring clean and clear pool water.
A hydraulic pressure gauge is a device used to measure and display the pressure within a hydraulic system.
It helps ensure that the pressure remains within safe and optimal levels for the proper functioning of the hydraulic system.
Hydraulic pressure gauges are built to withstand high pressures, vibration, and harsh operating conditions commonly found in hydraulic systems.
They provide accurate and reliable measurements, helping operators monitor system performance and prevent potential issues.
Hydraulic pressure gauges are essential tools used in various industries, including manufacturing, construction, and aerospace, where hydraulic systems are widely used for power transmission.

A pressure gauge is an instrument used to measure and display the pressure of a fluid (liquid or gas) in a closed system. Its primary function is to provide real-time information about the pressure, enabling operators to monitor and control processes effectively.
The bourdon pressure gauge is the most common type - it is a mechanical gauge that utilizes a curved tube that straightens under pressure, allowing you to see the readings on a dial.
Bourdon pressure gauges are known for
Dry pressure gauges are sealed and contain air. They are less complex than liquid-fille gauges and typically more affordable, however, they are not as accurate and require regular calibration. Liquid-filled gauges are filled with oil or glycerine that lubricates movement, making them more accurate. They are also more resistant to vibrations and can withstand bigger temperature changes. At Hawleys, all of our bourdon pressure gauges are glycerin-filled.
The housing material of the pressure gauge is another key factor that contributes to its longevity and performance.
If the housing for our gauges is made of stainless steel, because this material is:
The difference between rear and bottom entry pressure gauges lies in how they are installed and where the pressure connection is located:
Bourdon Tube Gauges: they operate using a curved tube (Bourdon tube) that straightens under pressure, which is then converted into mechanical movement to indicate pressure on a dial.
Diaphragm Gauges: use a flexible diaphragm that deflects under pressure to measure changes in pressure. They are often used in applications where the pressure is relatively low or where vibration resistance is required.
Capsule Gauges: use a flexible capsule instead of a diaphragm to measure pressure changes. They are typically used in low-pressure applications.
Digital Gauges: use electronic sensors to measure pressure and display the reading digitally on a screen. They offer high accuracy and can often provide additional features such as data logging and remote monitoring.
Differential Pressure Gauges: can measure the difference in pressure between two points in a system. They are commonly used in applications such as flow measurement and filter monitoring.
Absolute Pressure Gauges: can measure pressure relative to a perfect vacuum, rather than atmospheric pressure. They are often used in scientific and laboratory applications.
Sealed Pressure Gauges: designed to prevent the ingress of contaminants into the gauge mechanism. They are commonly used in harsh environments or applications where cleanliness is essential.
Pressure gauges are commonly used in industries such as manufacturing, oil and gas, petrochemicals, pharmaceuticals, HVAC, aerospace, and more. They are essential for monitoring pressure in boilers, pipelines, hydraulic systems, and various mechanical equipment.
To select the right pressure gauge, consider factors like the pressure range, compatibility with the measured media, accuracy requirements, and environmental conditions. If you are not sure, contact us for a consult.
Analog pressure gauges use a dial and pointer to display pressure, while digital pressure gauges provide numeric readings on an electronic display. Analog gauges are suitable for quick visual reference, while digital gauges offer precise readings and data-logging capabilities.
Yes, safety precautions and installation guidelines are essential. Pressure gauges should be installed correctly, and safety measures taken to prevent overpressure or damage to the gauge. Follow manufacturer recommendations and industry standards.
Pressure gauges should be calibrated at regular intervals, typically annually, or as specified by the manufacturer. Calibration ensures accuracy, and reputable calibration services can provide certification.
Yes, pressure gauges can be integrated into control systems using protocols like 4-20mA or HART for remote monitoring. Digital pressure gauges often have built-in data logging and communication options such as USB or RS-485.
Pressure gauges may need to meet standards such as ASME B40.100 or DIN EN 837. Verify compliance by checking the gauge's specifications and documentation or consulting with the manufacturer or supplier.
