Description

Double-sided pressure gauge

Technical Field

The utility model relates to the technical field related to pressure gauges, in particular to a double-sided pressure gauge.

Background

A pressure gauge is a device that mates with a pipeline or pressure vessel, facilitating the user's understanding of what the fluid pressure is inside the current pipeline or pressure vessel. However, the mechanical pressure gauge can only be visually known by a user through the pointer, and cannot be used for collecting data in real time. Besides the pressure value can be displayed by the electronic pressure gauge, data output can be performed to collect data.

Although the mechanical pressure gauge can only display the pressure value by a pointer, the mechanical pressure gauge has the advantages of low cost, weather resistance, interference resistance and the like because of using mechanical structures such as a Bardon tube and the like. Although the electronic pressure gauge has the convenience of outputting electronic signals, the pressure sensing chip is used in the electronic pressure gauge to detect the pressure, so that the electronic pressure gauge has the defects of high cost, interference tolerance (such as temperature, humidity and the like) and the like, and is also frequently a problem of users.

Therefore, how to meet the cost problem and achieve the convenience of data collection is an improvement of the existing pressure gauge.

In addition, the pressure gauge has only a single display surface, when a user wants to observe the pressure scale of the pressure gauge, the user can only observe the pressure scale in a specific single direction, if the user is located at the back edge of the pressure gauge, the user needs to return to the position facing the specific display surface of the pressure gauge, and the user can visually know the pressure scale, so that not only is the inconvenience caused in work, but also unexpected defects are more likely to be caused because the pressure scale cannot be known at the first time, and the need for improvement is felt.
