Pressure gauges offered by Dambat are reliable measuring devices designed to control and monitor pressure in water, heating, and industrial systems, where precise measurement of the medium’s pressure is crucial for the safety and trouble-free operation of the system. Thanks to a suitably selected pressure measurement range, it is possible to measure water pressure, operating pressure, and gauge pressure in various applications—from domestic drinking water systems to advanced pumping and hydrophore systems.
Construction and operating principle of pressure gauges
A typical Bourdon tube pressure gauge uses a curved pressure tube that deforms under changes in the medium’s pressure and transfers movement to a pointer mechanism, providing a clear pressure reading on the dial. Such pressure gauges measure pressure relative to atmospheric pressure, that is, gauge pressure, giving the user clear information about the current condition of the system.
The range also includes diaphragm pressure gauges, in which liquid and gas pressure measurement is carried out through the deformation of a special diaphragm. This is particularly useful for measuring low pressures and in applications requiring greater resistance to medium contamination. These pressure gauges are based on proven measuring systems, and the operating temperature and pressure ranges are selected to enable safe operation across a wide range of industrial applications.
Types of pressure gauges and measurement ranges
Depending on the needs of the system, the use of pressure gauges includes classic devices for measuring operating pressure, a differential pressure gauge for measuring pressure differences, and specialist glycerin-filled pressure gauges designed to operate in conditions exposed to vibration and pulsation. Pressure gauges are available in various designs, making it possible to select a suitable measuring pressure gauge with the appropriate diameter, measurement range, and accuracy class.
The measurement range of a pressure gauge should cover the expected operating pressure with an appropriate safety margin, so that the pressure measured by the pressure gauges does not exceed the limit values specified for the given model. Individual pressure gauges cover ranges from measuring small pressures and low pressures, through typical operating pressures in water systems, to higher values required in more demanding technological systems.
Differential pressure gauge and pressure difference measurement
Specialist products such as our pressure gauges include differential solutions designed to operate in systems where pressure difference measurement and simultaneous monitoring of operating pressure are required. Such a differential pressure gauge enables precise measurement of differential pressure, which is particularly important when monitoring the condition of filters, heat exchangers, pumps, and other components where a pressure difference indicates the degree of contamination or system load.
Difference measurement and pressure difference indication are carried out using integrated process connections, to which the higher and lower medium pressures are supplied, while static pressure and differential pressure are taken into account in the device’s design. This makes it possible to continuously monitor pressure and measure differences even at relatively low pressure ranges, allowing an effective response to any pressure changes in the system.
Monitoring pressure in water systems
In drinking water supply systems, stable water pressure is essential. Therefore, measuring water pressure and determining the water pressure using an axial pressure gauge or a pressure gauge working with a pump controller helps maintain user comfort and protect devices against overload. An example of such a solution is the 1/4", 60 mm diameter axial pressure gauge, which enables precise pressure measurement in typical systems.
Dambat’s range also includes diaphragm tanks with a built-in pressure gauge, such as the 100 l tank with a pressure gauge, allowing for continuous pressure measurement and stabilization of water parameters in the system. This solution enables the user to observe pressure changes on an ongoing basis and quickly respond to any irregularities, which is important for protecting the pump and the entire system.
Pressure gauge selection and technical parameters
Proper pressure gauge selection requires determining basic parameters such as operating pressure, pressure range, pressure measurement range, and the maximum allowable pressure, which should not be reached under normal operating conditions of the system. The accuracy of the pressure gauge and its class are also important.
When selecting a product, it is worth considering offerings from Dambat, such as the 1/4", 60 mm diameter radial pressure gauge or the pressure reducer gauge, which provide an appropriate measurement range and solid construction. Thanks to the wide range of accessories, including components such as the five-way discharge outlet, it is possible to create a complete, highly reliable measuring system.
Pressure gauges in pump automation systems
Pressure gauges also play an important role in pump automation systems, working together with electronic controllers and pressure switches. Solutions such as the PC-2 switch integrated with a pressure gauge, available on the Dambat website, facilitate pressure monitoring and the automatic switching on and off of the pump depending on the current medium pressure.
Thanks to pressure gauges working with controllers such as the intelligent WATER-PASS controllers, it is possible to precisely monitor pressure and adjust pump operation to water demand. This ensures high user comfort, protects system components, optimizes energy consumption, and also enables easy pressure measurement and monitoring of the operating parameters of the entire system.
