How can we use the Pressure Gauge Set correctly?

Pressure Gauge Set In the process of industrial process control and technical measurement, due to the high mechanical strength and convenient production of the elastic sensitive element of the mechanical pressure gauge, the mechanical pressure gauge is more and more widely used.

What are the precautions for using the Pressure Gauge Set?

1. The use range of the Pressure Gauge Set should be between 1/3 and 2/3 of the upper limit;

2. When measuring corrosive media, media that may crystallize, and media with high viscosity, an isolation device should be added;

3. The Pressure Gauge Set should be checked frequently (at least once every three months), and if any fault is found, it should be repaired in time;

4. If the Pressure Gauge Set is found to be invalid or damaged due to poor manufacturing quality under normal storage and use conditions within half a year from the date of delivery, the company will be responsible for repairing or replacing it;

5. Instruments for measuring corrosive media should be used, and the requirements should be specified when ordering.

What is the pressure representation in the Pressure Gauge Set?

There are two ways to express the pressure of Pressure Gauge Set: one is the pressure expressed by absolute vacuum as a reference, which is called absolute pressure; the other is the pressure expressed by atmospheric pressure as a reference, called relative pressure. Since the pressure measured by most Pressure Gauge Sets is relative pressure, relative pressure is also called gauge pressure. When the absolute pressure is less than the atmospheric pressure, it can be expressed by the value that the absolute pressure in the container is less than one atmospheric pressure. It is called "vacuum degree". Their relationship is as follows:

Absolute pressure = atmospheric pressure + relative pressure

vacuum = atmospheric pressure - absolute pressure

How is the Pressure Gauge Set installed?

1. The installation position of the Pressure Gauge Set should meet the requirements of the installation state. Generally, the dial should not be placed horizontally, and the height of the installation position should be easy for the staff to observe.

2. The distance between the installation place of the Pressure Gauge Set and the pressure measuring point should be as short as possible, to ensure the integrity of the sealing, and there should be no leakage.

3. There should be a buffer at the front end of the installed Pressure Gauge Set; for the convenience of inspection, a shut-off valve should be installed under the instrument; when the medium is dirty or there is pulse pressure, filters, buffers and stabilized gas can be used.
