Digital Pressure Gauge Security Trends
- Nov 06, 2017 -

Pressure gauges are common measuring instruments and are widely used in various fields. Digital Pressure Gauge It can visually show the pressure change of each process link, insight into the formation of conditions in the product or media process, monitor the safety trends in the production process, and construct a rapid and reliable safety guarantee by automatic chain or sensor device, Digital Pressure Gauge which plays an important role in preventing accidents, safeguarding personal and property safety, and is called safe " Eyes. "

(1) The range of the digital pressure gauge on the boiler and pressure vessel, and the maximum range (scale limit on the dial) should be suitable to the working pressure of the equipment. The range of the digital pressure gauge is generally 1 of the working pressure of the equipment. 5~3 times, Digital Pressure Gauge it is best to take twice times. If the number of digital pressure gauges selected is too large, due to the same precision of the digital pressure gauge, the larger the range, allowing the absolute value of the error and the visual observation of the deviation will be greater, will affect the accuracy of pressure readings; Conversely, if the number of digital pressure gauge is too small, the working pressure of the equipment equals to or close to the scale limit It will make the elastic element in the digital pressure gauge to be in the biggest deformation state for a long time, Digital Pressure Gauge and can produce permanent deformation, which causes the error of the digital pressure gauge to increase and the service life to decrease. In addition, the scale of the digital pressure gauge is too small, in case of overpressure operation, the pointer over the maximum distance of nearly 0, and the operator to create an illusion, resulting in a greater accident. Digital Pressure Gauge Therefore, the use pressure range of the digital pressure gauge should not exceed the $number of the scale limit.

(2) The accuracy of the digital pressure gauge for work is expressed by the allowable error as a percentage of the dial scale limit value. Precision grades are generally marked on the dial, Digital Pressure Gauge the use of digital pressure gauges, should be based on the equipment pressure level and actual work needs to determine the accuracy.

(3) Dial diameter in order to enable operators to accurately see the pressure value, the digital pressure gauge dial diameter should not be too small, Digital Pressure Gauge if the digital pressure gauge installed higher or farther away from the position, the dial diameter should be increased.

(4) The digital pressure gauge used for the measurement of medium if there is corrosive, then must be based on the corrosive medium specific temperature, concentration and other parameters to choose different elastic element materials, otherwise not achieve the intended purpose.

(5) Daily attention to the use of maintenance, regular inspection, cleaning and good use of records.

(6) The general verification cycle of digital pressure gauges is six months. Compulsory verification is a legal measure to guarantee the reliable performance of digital pressure gauge, accurate transmission of quantity value and effective guarantee of safe production.
