hongqi Y50ZT 2"chrome plated steel back pressure gauge with flange CE/UL/KS
Back connection mechanical manometers are pressure measuring devices that have a connection at the back of the manometer for connection of pressure tubing or piping. They are frequently used in HVAC and refrigeration systems, as well as in industrial processes. They work based on the principle of converting pressure to a mechanical displacement, which is then indicated on a graduated scale. The back connection feature of these manometers makes them easy to install in line with the pressure source and to monitor pressure at the desired location. They have the advantage of being simple, reliable, and cost-effective. However, they require regular calibration and may have accuracy limitations in high-pressure ranges.
A chrome plated steel pressure gauge is a instrument that measures the pressure of a fluid or gas in a system. It is made of steel that is coated with chrome to protect it from corrosion and improve its aesthetic appearance. The gauge typically has a circular dial with markings that indicate the level of pressure in units such as psi, bar, or kPa. The gauge is commonly used in industrial, commercial, and residential applications, such as in HVAC systems, oil refineries, and gas pipelines, to ensure that the pressure in the system is within safe and efficient operating levels.
