Detail:
The film box pressure gauge is also called a micro pressure gauge. Structure principle is to increase the displacement of the diaphragm, improve the sensitivity of the pressure gauge and the two concentric diaphragm welded together, made of hollow film box, and film box as an elastic sensitive element is used to measure the micro pressure gauge called the film box.
The film box pressure gauge is composed of a measuring system, a rotating indicating device and an outer shell. The working principle of the meter is based on the elastic deformation of the free end of the corrugated film box under the pressure of the medium.
Product use:
Stainless steel film box pressure gauge with the characteristics of the structure of the original film box pressure gauge and the corrosion resistance of the micro gauge. The micro pressure and negative pressure of various kinds of gas medium are measured in the process flow of boiler ventilation and gas pipeline and other equipment. Accuracy class: 2.5.
