General pressure gauges are instruments with a single-turn "C"-shaped spring tube structure, a Class 1 accuracy rating, and a measurement range exceeding atmospheric pressure. They are used to measure the gauge pressure of liquids, gases, and steam that are non-corrosive to instrument components. These include industrial single-turn spring tube pressure gauges (ordinary pressure gauges), pressure and vacuum gauges, oxygen pressure gauges, and electric contact pressure gauges.
General pressure gauges offer advantages such as simple structure, low cost, a wide measurement range, clear indication, durability, ease of use and maintenance, and safe and reliable operation. They are minimally affected by normal vibration conditions and offer sufficient accuracy and indication stability. Common applications include monitoring the operating conditions of the medium in pressure vessels, understanding material changes during production, and providing reliable information for operators to monitor, control, and adjust production by understanding pressure parameters.
It is important to note that a pressure gauge lacking adequate accuracy may compromise the safety of personnel and industrial processes.
