What is a Radial Pulse?

The radial direction of the pressure gauge means that the threaded joint of the pressure gauge is parallel to the dial. It is used to measure the pressure or vacuum of liquids, gases and vapors that have no explosion hazard, do not crystallize, do not solidify, and do not corrode copper and copper alloys.

Distinguish from range and range

In the positive pressure range, it is divided into a micro-pressure range section, a low-pressure range section, a medium-pressure range section, a high-pressure range section, and an ultra-high-pressure range section. Each range section is subdivided into several measurement ranges ( Instrument range); in the negative pressure range, there are three kinds of negative pressure; the axial pressure gauge of the positive pressure and negative pressure joint is an axial pressure gauge that spans the range. Its standard name is pressure vacuum gauge, also called vacuum axial pressure gauge. It can measure not only positive pressure but also negative pressure.

Distinguish from measurement accuracy

Can be divided into precision radial pressure gauge, general radial pressure gauge. The measurement accuracy levels of precision radial pressure gauges are 0.1, 0.16, 0.25, 0.4 and 0.05 respectively; the accuracy levels of general radial pressure gauges are 1.0, 1.6, 2.5, and 4.0.

Distinguish from measurement basis

Radial pressure gauges are divided into general radial pressure gauges, absolute radial pressure gauges, stainless steel radial pressure gauges, and differential pressure gauges according to the basis of their indicated pressure. General radial pressure gauges are based on atmospheric pressure; absolute pressure gauges are based on absolute zero pressure; differential pressure gauges measure the difference between two measured pressures. ^[2]

The use of radial pressure gauges is extremely common, and it covers almost all industrial processes and scientific research fields. Pressure gauges can be found everywhere in heat pipe networks, oil and gas transmission, water supply and gas supply systems, vehicle maintenance and repair shops, etc. It is mainly used to measure the pressure of the medium. ^[2]

(1) The installation position should meet the requirements of the installation status. The dial should generally not be placed horizontally, and the height of the installation position should be easy for workers to observe.

(2) The distance between the installation place and the pressure measurement point should be as short as possible, to ensure a perfect seal, and no leakage phenomenon should occur.

(3) There should be a buffer at the front of the installed radial pressure gauge; to facilitate inspection, a shut-off valve should be installed below the instrument; when the medium is dirty or there is a pulse pressure, a filter, buffer and pressure tank can be used Wait.
