Mining Pressure Gauge

Mining pressure gauges are produced and designed in compliance with EN837-1 standard for the mining industry. Mainly used for simple pressure measurement of liquids, vapour and gases, that do not have corrosive effect on copper allows and their viscosity allows for use of bourdon pen measurement mechanism. Designed for use in mining industry. GC-BOB had over 20 years manufacturer on this gauge.

GC gauge provides high-quality bourdon tube type pressure gauge for sale. Our Bourdon tube pressure gauges are independently researched, certified and manufactured with the 837-1 standard compliant. GC gauge also provides commonly used measurement ranges, process connections, certifications and national sizes of the world. A fluid-filled Bourdon tube pressure gauge is also made for sale. Our pressure gauges for mining can meet the application of gauge pressure, absolute pressure and we have differential manometer bourdon pressure gauge to fulfill differential pressure measurement. Our bourdon pressure gauge also have been tested millions of times in practice. GC gauge provide measurement systems using Bourdon tube and can provide suitable solutions for customers' different applications.


Types of Mining Pressure Gauge Wholesale


What is Bourdon Tube Type Pressure Gauge?

The double-needle seismic pressure gauge for mining of is used to measure the pressure of the hydraulic transmission system of the fully mechanized coal mining. It can resist the influence of the vibration of the working environment and the pressure of the medium. It has the performance of precise measurement accuracy and precision, and can accurately record the instantaneous pressure in the pressure system. Filling the shell with fluid, it can be insured that the bourdon tube manometer has an accurate specificity and a high dynamic pressure. It can cushion the moving parts in the housing to prevent damage and wear.

 

What are the types of Bourdon Tube Pressure Gauge?

There are different types of bourdon tube pressure gauges such as the general pressure gauge, small pressure gauge, sealed pressure gauge like oil-filled pressure gauge. These will be used according to the location of the pressure gauge and the type of fluid. A general pressure gauge is usually used, but the pressure gauge will partly protrude from the pipeline when it is connected. Therefore, a small pressure gauge is needed if it is installed in a place where space cannot be ensured to avoid the trouble of optimizing the pipeline. In addition, when the bourdon pressure gauge is working outdoors, the effects of rain and dew must be considered. In this case, a sealed pressure gauge can be used. The glycerin-filled pressure gauge is sealed with glycerin inside. In this way, the displacement speed when receiving pressure can be adjusted, and the sensitivity can be reduced. Even if the pressure in the tube changes, the pointer in the meter will not work immediately. The advantage of using a pressure gauge filled with glycerin is that in a vibrating environment and when the measured fluid is subject to severe pulsation, the pressure gauge still has good sensitivity.

 

How does a Mechanical Pressure Gauge Work?

The working principle of a mechanical pressure gauge is: when the elastic shape of the sensitive components (Bourdon tube, bellows, retube)inside the gauge are under pressure, they have elastic deformation. Then the conversion mechanism of the movement in the watch transmits the pressure deformation to the pointer, causing the pointer to rotate to display the pressure.

The Bourdon tube pressure gauge is a spring tube pressure gauge. It’s working principle is: under the action of pressure, the free end of the spring tube produces displacement. The displacement is rotated by the pull rod to rotate the magnifying mechanism, and the measured pressure value is indicated on the peripheral disc.
