Precise use of digital pressure gauges

[China Aluminum Network] The internal structure of the precision digital press is very precise. There are many areas that we need to pay attention to in the process of use. Often a wrong use method will cause the product to damage a large number of functions and even cause the product to be scrapped. In response to this problem, the following Xiao Bian gave you a brief article explaining what you need to pay attention to when using precision digital pressure gauges.

First of all, we first talk about the function of precision digital pressure gauges, which are widely used in various fields. In addition, it can intuitively display the pressure changes in various process steps, provide insight into the formation of conditions in the product or medium flow, monitor the safety trends in the production and operation process, and build a fast and reliable security guarantee through automatic interlocking or sensing devices. It has played an important role in preventing accidents and ensuring the safety of people and property. It is called the "eyes" of security displays.

(1) Precision digital pressure gauge Digital pressure gauges installed on boilers and pressure vessels. The larger range (scale limit value on the dial) should be compatible with the working pressure of the equipment. The range of precision digital pressure gauges is generally 1.5 to 3 times the working pressure of the equipment, preferably 2 times. If the digital pressure gauge selected is too large, due to the precision of the digital pressure gauge with the same accuracy, the larger the range, the larger the allowable error value and the visual observation deviation will affect the accuracy of the pressure reading; otherwise, if the selected If the digital pressure gauge is too small and the working pressure of the equipment is equal to or close to the scale limit of the precision digital pressure gauge, the elastic element in the digital pressure gauge will be in a large deformation state for a long time, and it will easily produce a longer deformation, which will result in precise digital pressure. The error of the meter increases and the service life decreases. In addition, the range of the precision digital pressure gauge is too small. In the event of overpressure operation, the pointer will cross over a large range close to zero, causing an illusion of the operator and causing a greater accident. Therefore, the pressure range of precision digital pressure gauges should not exceed 60 to 70% of the scale limit.

(2) The accuracy of the digital pressure gauge for work is represented by the allowable error as a percentage of the dial scale limit value. Accuracy grades are generally marked on the dial, use precision digital pressure timing, the accuracy should be determined according to the pressure level of the equipment and the actual work needs.

(3) Dial diameter In order for the operator to accurately see the pressure value, the diameter of the dial of the digital pressure gauge should not be too small. If the digital pressure gauge is installed higher or farther from the post, the diameter of the dial should increase.

(4) If the medium used for measuring precision digital pressure gauges is corrosive, different elastic component materials must be selected according to the specific temperature, concentration, and other parameters of the corrosive medium. Otherwise, the intended purpose may not be achieved.

(5) Pay attention to the use of daily maintenance, regular inspection, cleaning and record of usage.

(6) The general verification period for a precision digital pressure gauge is six months. Mandatory testing is a legal measure to guarantee the reliable performance of precision digital pressure gauges, accurate value transfer, and effective guarantee of safe production.

The above is the relevant answer that Xiaobian has made for the matters needing attention in the use of precision digital presses. I believe that after you read the above article, you will be able to use more accurate digital pressure timing to make it easier to operate.
