Two types of precision digital pressure gauges
2011-5-23 16:35:15

The types of precision digital pressure gauges currently on the market are:

1. Pointer type precision digital pressure gauge . 2.Digital display precision digital pressure gauge

    Pointer precision digital pressure gauges are equipped with different types of mounting structures, such as radial band edge precision pressure gauges and axial band edge precision pressure gauges.

The so-called precision digital pressure gauge refers to a high-precision pointer pressure gauge, which is generally a direct reading type. Precision pressure gauges of different accuracy grades have differences in reading resolution in addition to allowing basic errors. For example: China Precision Pressure The national standard of the table stipulates a precision pressure gauge of class 1.6 and 1.6 MPa, the scale of the dial scale is 160 divisions, and a precision gauge of class 0.25 and 1.6 MPa, the scale of the dial scale is 320 divisions. Obviously, The dial score line must have a high reading accuracy, which can reduce the reading parallax of the precision pressure gauge .

In order to ensure the reading accuracy of the precision digital pressure gauge , the dial of the precision digital pressure gauge is provided with a mirror ring to improve the reading accuracy to correct the reading position and improve the reading accuracy of the precision digital pressure gauge .

In China ’s national standard for precision digital pressure gauges , it is also stipulated that the scale line is a full-thin line not larger than 0.2mm, and the ratio of the long and short lines is 2: 1 ... When choosing a precision pressure gauge , do not ignore the precision pressure gauge . Resolution. Weigh the precision pressure gauges you need.
