Pressure gauges for pressure measurement

Gauges — this device (devices), designed for measuring pressures of gas, liquid. Devices are classified into several types, depending on signs. Before selecting a pressure gauges pressure measurement, you should be familiar with the peculiarities of their usage.

Choosing devices according to the measured pressure range

 The pressure Gauge. The device allows you to measure the positive difference between the absolute pressure and barometer pressure in the range from 0.06 to 1000 MPa.

- draft meter. Measures a vacuum of 40 kPa.

is the Vacuum gauge. Allows you to measure pressure below the ambient (atmospheric) to 100 kPa.

- Napremer. Measuring small excess pressure (about 40 kPa).

- Tranporter. The measurement ranges correspond to the interval from-20 to + 20 kPa.

vacuum pressure gauge. It includes pressure gauges to measure the excess pressure (from 60 to 240 000 kPa) and vacuum (up to-100 kPa).

- the differential pressure Gauge. The device is intended for measuring differential pressure.

The Most used devices are the differential and absolute pressure. Differential devices (pressure gauges) for pressure measurement shows the difference between the two quantities. Pressure gauges show the absolute value independently of pressure fluctuations in the atmosphere.

Features, structure gauges

Pressure Gauges for pressure measurement are divided into several types, depending on the design and structure of instruments: liquid-filled, dead weight, deformation of the diaphragm deformation to the tubular spring (Bourdon tube). The item gives you the ability to measure the pressure of a high degree of accuracy.

In medicine, used diaphragm pressure gauges. They are the most pure in environmental terms, the quality is not worse than mercury.

Very common are pressure gauges for measuring gas pressure. They consist of a housing, which houses the gauges. Devices are installed in compressors, pumps, gas equipment. Gas pressure gauges are accurate in the testimony.

The Gauges of any kind are classified in terms of accuracy. The smaller the number, the device shows a more correct value. Accuracy classes are as follows: 0,15; 0,25; 0,4; 0,6; 1,0; 1,5; 2,5; 4,0.

Scope of application of the gauge

Purposes at the gauges much. They come in electric, General, reference, recorder, for special purposes.

- Electric-contact pressure gauges are used for monitoring and measuring pressure in liquid and gaseous non-aggressive environments.

- Technical manometers used for measuring pressure of steam, gas, liquid.

- the Reference pressure gauges have high accuracy rate. They make inspection and calibration of other devices. Mostly, they are placed on the dead weight of the device.

- the Gauges with chart recorder, record the pressure reading on special mechanism-carrier.

- the Gauges special purpose provide the desired environmental conditions. These include: oxygen (blue), acetylene (white), hydrogen (green and gray) devices. Different colors are necessary to avoid negative consequences. For example, oxygen equipment must be degreased, otherwise contaminated by contact of the device with pure oxygen could cause an explosion.

Pressure Gauge for measuring the pressure of the fuel can be used in various industries. When choosing a device, you should know that a quality product can only be purchased from reputable manufacturer, with a worldwide reputation. The manufacturer must have a license for the right of release of goods, the quality certificate. This is a very important fact. Because measuring instruments are used in complex technological and production processes. And from them depends the safety of the work progress and the quality of the final product.
