Pressure Gauges,Manometers,Pressure Gauges For Measuring The Pressure Of Gaseous Media
Pressure gauges are instruments that use elastic elements as sensitive components to measure and indicate pressure above ambient.
Pressure gauge refers to the elastic element as the sensitive element, measuring and indicating higher than the ambient pressure of the instrument, the application is extremely common, it is almost all over the industrial process and scientific research field. In the heat pipe network, oil and gas transmission, water and gas supply systems, vehicle maintenance stores and other fields can be found everywhere. Especially in the industrial process control and technical measurement process, due to the mechanical pressure gauge of the elastic sensitive element has a high mechanical strength as well as the production of convenient and so on.
Working Principle: Pressure gauge through the table within the sensitive components (Borden tube, membrane box, bellows) of the elastic deformation, and then by the table movement of the conversion mechanism will be the deformation of pressure conduction to the pointer, causing the pointer to rotate to display the pressure.
Main structure
Overflow hole: In case of an emergency situation where the bourdon tube bursts, the internal pressure will be released to the outside world through the overflow hole to prevent the glass panel from bursting.
Note: In order to maintain the normal performance of the overflow hole, it is necessary to leave a space of at least 10mm behind the watch, and the overflow hole should not be remodeled or plugged.
Hands: In addition to the standard hands, other hands are optional.
Glass panel: In addition to the standard glass, other special material glass, such as reinforced glass, non-reflective glass is also optional.
Performance classification: General type (standard), general type for steam (M), heat-resistant type (H), vibration-resistant type (V), vibration-resistant type for steam (MV) heat-resistant vibration-resistant type (HV).
Treatment: No oil/water treatment Water or oil residue in the liquid-access portion is removed at the time of manufacture.
External designation: Shell color other than standard color to be specified.
Throttle valve (optional): To reduce pulsating pressure, a throttle valve is mounted at the pressure inlet.
