Differential pressure gauge, a differential pressure gauge is an instrument used to measure the difference (differential pressure) between two pressures.

Working Principle of Differential Pressure Gauge    

The working principle of a differenstrykmåler is based on the principle of spring force balance or diaphragm deformation. Specifically, it includes two or more pressure sensors located on either side of the measurement system to sense pressure values at different positions. When there is a pressure difference between the two sides, these pressures will act on the spring or diaphragm inside the differential pressure gauge, causing deformation of the spring or displacement of the diaphragm. This deformation or displacement is directly proportional to the differential pressure value and is converted into the rotation of the pointer on the dial through a mechanical transmission mechanism (such as gear transmission), indicating the magnitude of the differential pressure. When the differential pressure is zero, the spring or diaphragm is in equilibrium and the pointer indicates zero position.

Characteristics of Differential Pressure Gauge   

High precision measurement: Differential pressure gauges can accurately measure the small difference between two pressures, meeting the requirements of high-precision measurement. Its accuracy level can be selected according to actual application requirements to adapt to different measurement scenarios.

Wide applicability: Differential pressure gauges  are suitable for pressure measurement in various media and environments, including gases, liquids, and vapors. At the same time, its structural forms are diverse, such as membrane type, corrugated tube type, etc., which can be flexibly selected according to the measurement medium and measurement range.

Good stability: Differential pressure gauges are designed with emphasis on stability and reliability, and can maintain stable measurement performance in harsh working environments. Its internal components are made of high-quality materials and have a long service life.

Easy to install and maintain: Differential pressure gauges typically have simple and intuitive installation interfaces and maintenance methods, making it convenient for users to install and perform daily maintenance. At the same time, its clear indication and convenient reading help users quickly obtain measurement data.

Multiple output methods: Modern differenstrykmåler not only have mechanical indication functions, but can also convert differential pressure signals into electrical signals for output through appropriate converters and signal processing equipment. This electrical signal output method is easy to integrate with automation control systems, enabling remote monitoring and data collection.

In summary, the differenstrykmåler, as an important pressure measuring instrument, plays a crucial role in industrial production, scientific research, and other fields due to its high precision, wide applicability, good stability, easy installation and maintenance, and multiple output modes.
