What components does the pressure gauge set consist of?

The working principle of the manometer set is based on the elastic deformation of the sensitive elements (Bourdon tube, bellows, bellows) in the watch, and then the pressure deformation is transferred to the hand through the conversion mechanism of the movement, which turns the pointer to indicate the pressure. Spring tubes (Bourdon tubes) are divided into shape tubes, coil spring tubes, spiral tubes and other types. In general, pipe blanks made of cold-hardened material are used, which have a high plasticity when annealed. After cold hardening and qualitative treatment by compression, you get high elasticity and strength. The spring tube of the pressure gauge set can easily convert the pressure into the elastic displacement of the free end of the spring tube due to its elastic properties under the action of the inner cavity pressure.

How does the pressure gauge set work?

The measuring range of the spring tube in the manometer set is generally such that the membrane-sensitive element is a circular diaphragm with shafts and the diaphragm itself is arranged between two flanges or is welded to the flange or its edge between the two in between lies the flanges. One side of the diaphragm is applied with the pressure of the measuring medium, so that the low bending deformation of the diaphragm can be used for indirect measurement of the medium pressure and the size of the pressure is indicated by the pointer. Compared to the tube spring, the diaphragm has a greater transmission force. Since the circumference of the membrane itself is fixed, its vibration resistance is better. The diaphragm manometer of the manometer set can achieve high overpressure protection (for example, the diaphragm is attached to the upper flange), and the diaphragm can also be coated with a protective varnish to improve the corrosion resistance. During measures such as opening, the diaphragm spring manometer can be used to measure the medium with high viscosity, contamination and crystallization. The pressure measurement range of the diaphragm manometer is 1600Pa to 2.5 MPa.

What are the selection criteria for the pressure gauge set?

The pressure gauge can be used to monitor the pressure of each operating point of the hydraulic system for adjustment and control. The selection of the pressure gauge should be based on the production requirements of the use process and a specific analysis should be carried out according to the specific situation.

The selection of the pressure gauge set must meet the requirements of process manufacturing. Whether remote transmission, automatic recording or alerting; whether the characteristics of the medium to be measured (such as temperature, viscosity, corrosivity, degree of contamination, flammability and explosion of the measuring medium, etc.) Environmental conditions (such as humidity, temperature, magnetic field strength, vibration, etc.). require instrument types, etc.

To meet these growing demands, Guangzhou HERUI offers various pressure gauge sets, all of which are more effective, reliable and consistent.
