Manometer (pressure gauge)

As you know, the main prerequisite for doing any work is to have proper information about that subject. In order to choose, review the wholesale prices, buy, and know more about manometers (pressure gauges), the following contents are included so that you, dear visitors of the specialized website of Damatajhiz, can use this information to choose and buy all types of manometers (pressure gauges), such as digital, oil, standing, pointer & vacuum pressure gauge from brands Vika, Pickens, Beta, Bentec, TJ, Wilmer, etc. in bulk.

C Type Tube Pressure Gauge

(Bourdon tube) blocked on one side and connected to the pressure point on the other tube (Bourdon tube) that is blocked on one side and connected to the pressure point on the other side. When the pressure enters one end of the line from the pressure point, it causes the Bourdon tube to move, and then it moves the gear wheel and the hand with a lever, and the movement of the hand displays the pressure. These pressure gauges can measure fluid pressures from 30 to 50,000 pounds per square inch (PSI).

Spiral manometer

In addition to the C-shaped Bourdon tube, there are two types of spiral and spiral Bourdon tubes. In this type of pressure gauge operation, the maximum possible displacement is proportional to the bending angle of the tube, and for the C-shaped Bourdon tube, the arc size is less than 360 degrees.

In cases where more sensitivity is needed to measure pressure, spiral or spiral Bourdon tubes are used. Also, spiral and spiral bourdon tubes occupy less space.

C-shaped bourdon tubes with a radius of 25 mm can be displaced up to 4 mm and are used to measure pressure up to 6000 bar, While spiral and bourdon tubes can measure pressure up to 700 bar.

U-shaped manometer

Some other manometers or pressure gauges have a U-shaped tube, one end of which is open, and the other end is connected to the gas source. The inside of this tube is filled with liquid or mercury. Typically, the height of the mercury on both sides of the pipe is equal, but as soon as the valve on the top of the pipe is opened and gas enters it, the height of the mercury on one side of the pipe changes, and in this way, they calculate the gas pressure.

This manometer measures low pressures (0 to 4 inches of water) and high pressures (0 to 48 inches of mercury).

As a result, a manometer measures the pressure, vacuum, or pressure difference between two points. An operator usually observes and records the pressure in this simple pressure measurement method.

Diagonal manometer

Another type of manometer is the oblique manometer, which measures low pressures (up to 0.5 inches of water).

Types of manometer or pressure gauge in terms of pressure type

Manometer with absolute pressure sensor

These pressure gauges measure the pressure of a point relative to a vacuum.

• (vacuum pressure = 0psi)
• (atmospheric pressure at the level of open seas = 101.325Pa)
• (atmospheric pressure at altitudes of 1000, 2000, 5000, 10000, and 20000 cubic meters = 89.88, 79.5, 54.05, 26.5, 5.53 kPa)

Manometer with gauge pressure sensor

This sensor measures the pressure at one point compared to the atmospheric pressure at another.

Manometer with vacuum pressure sensor

This sensor measure pressures lower than atmospheric pressure at a point.

Manometer with differential pressure sensor
This sensor measures the difference between two input pressures. (for example, to measure the flow rate or level in tanks)

Manometer with sealed pressure sensor

The function of this sensor is the same as the pressure gauge sensor, with the difference that the pressure is measured relative to the sea level pressure. (for example, to measure pressure changes in airplanes, rockets, satellites, and weather balloons)

In the group of manometers (pressure gauges), reference site and Damatajhiz store, information, and prices of various types of manometers (pressure gauges), including dry manometers, oil manometers, thermometers, manometers, etc., from the brands of Pickens, TJ, Wilmer, Vika, etc. Review and select.
