Description

Pressure gauge reinforced by iron plate

Technical Field

The utility model relates to a manometer field, more specifically says that it relates to an utilize reinforced (rfd) manometer of iron plate.

Background

The pressure gauge is a meter which is widely applied and almost extends to all industrial processes and scientific research fields, wherein the pressure gauge is used for displaying pressure by the rotation of a pointer through the elastic deformation of sensitive elements (Bourdon tube, bellows and bellows) in the gauge and then transmitting the pressure deformation to the pointer through a conversion mechanism of a movement in the gauge, and the pointer is used for measuring and indicating the pressure higher than the ambient pressure. The method is widely available in the fields of heating power pipe networks, oil and gas transmission, water and gas supply systems, vehicle maintenance plants and shops and the like. The pressure gauges are various in types, and not only have a general (common) pointer indication type, but also have a digital type; not only conventional type, but also special type; not only the contact type but also the remote transmission type; the vibration-resistant type and the vibration-resistant type are provided; there are not only a diaphragm type but also a corrosion-resistant type.
