Radial Pressure Gauge 100mm Copper Joint Iron Shell M20*1.5

PRODUCT DETAILS

PRODUCT DESCRIPTION

Instrument for measuring the condition of a fluid (liquid or gas) that is specified by the force that the fluid would exert, when at rest, on a unit area, such as pounds per square inch or newtons per square centimetre.

The reading on a gauge, which is the difference between two pressures, is known as the gauge pressure. If the lower of the pressures is the pressure of the atmosphere, the total, or absolute, pressure is the sum of the gauge and atmospheric pressures.

The simplest device for measuring static pressures up to about 90 pounds per square inch (62 newtons per square cm) is a U-tube manometer (shown in the figure), in which one column of a liquid in the tube is open to a region of high pressure and the other column to a region of low pressure. The differential pressure is indicated by the difference in level between the two columns of liquid, and it is calculated as the difference in level multiplied by the density of the liquid. The manometer liquids most commonly used are mercury, oil, alcohol, and water.

Manometer pressure gauges measure pressure on a fluid by balancing one column of fluid against a second column of fluid. This type of pressure gauge is the simplest type and consists of a transparent tube in the form of a “U” that is partially filled with a manometric fluid like mercury.

Absolute pressure gauges are used to measure pressure independent of the natural fluctuations in atmospheric pressure. A reference vacuum is attached to the side of the measuring element, which is not subject to pressure; it has zero pressure with no variation.

Capsule pressure gauge: The sensitive element of the bellows is composed of two diaphragms connected together with circular waves. The pressure of the measuring medium acts on the inside of the capsule cavity, and the resulting deformation can be used to indirectly measure the pressure of the medium. The size of the pressure value is displayed by the pointer. The bellows pressure gauge is generally used to measure the pressure of the gas, and can measure the micro pressure, and the overpressure protection is also possible to a certain extent. When several capsule sensitive components are stacked together, they will produce a large transmission force to measure extremely small pressure.

Main structure

Overflow hole: In the event of an emergency that the Bourdon tube bursts, the internal pressure will be released to the outside through the overflow hole to prevent the glass panel from bursting. Note: In order to maintain the normal performance of the overflow hole, a space of at least 10mm must be left behind the table, and the overflow hole cannot be modified or plugged.
Pointer: In addition to standard pointers, other pointers are also optional.
