GC-BOB is our registered brand for pressure gauges, it is based on good quality for pressure, vacuum, absolute and differential and so on pressure for the widest range of applications, there is a choice of measuring systems in Bourdon tube, diaphragm element and capsule element, spiral tube technologies.
The pressure gauges, made by our pressure gauge factory, cover scale ranges from 0 - 0.5 mbar to 0 - 4,000 bar and indication accuracies of up to 0.25 %. For the various requirements in industrial and process instrumentation there are pressure elements from copper alloys, stainless steel or special materials available. The dimension from 1" to 10 inch available. Custom pressure gauge is also fully supported, Welcome inquiry for the pressure gauge meter for different usage, we will give you the best solution.
With more than 20 years, we have manufactured high and low pressure gauges of high-quality and gained good reputation especially in the field of the oil free oxygen clean certified pressure gauge. GC Pressure Gauges has acquired a lot of professional pressure measuring apparatus certifications such as UL, ISO, CE, etc. With different types of pressure gauges, GC Pressure Gauges cooperates with many big medical companies in the world, specially in the USA and Europe. Besides, we have developed the leading intelligent high accuracy WIFI pressure gauges to adapt to the demanding requirements from our customers.
General pressure gauge can be interoperability, which means the commonly used hydraulic oil pressure gauge and air pressure gauge can be used interchangeably as long as the range and precision can keep constant. If it is corrosive medium, you can only use air pressure gauge, such as oxygen, hydrogen, ammonia pressure gauge. Under such circumstance, hydraulic oil pressure gauge is not advisable to apply in these medium. In fact, the pressure of each working point of the hydraulic system can be observed through the hydraulic oil pressure gauge for adjustment and control. Therefore, the selection of the pressure gauge should be based on the production requirements of the use process, and specific analysis should be made for the specific situation.
The fluid pressure of the hydraulic system is caused by the extrusion of the hydraulic oil by the load. Therefore the hydraulic gauge can express the the amount of fluid pressure.
Generally speaking, a standard pressure gauge is reading the total pressure minus the atmospheric pressure. The unit for a high precision pressure gauge reading relative pressure is psi (pounds per square inch) or psig (pounds per square inch gauge).
The low pressure gauge is the pressure lower than 15psi/1bar. We should use the capsule membrane to instead the bourdon tube style pressure gauge. By the way, the high pressure gauge is the pressure more than 250bar/psi.
