Digital Pressure Gauge Test Requirements
- Jul 24, 2017 -

Pressure gauge in fact, regardless of hydraulic or pressure, that is, Digital Pressure Gauge hydraulic pressure gauge, can also be used in air pressure test. The pressure gauge on the hydraulic station can also be used in steel drums. The most important thing is that the pressure gauge pressure range to meet the test requirements.

In order to reasonable, Digital Pressure Gauge the economic use of pressure gauges, Digital Pressure Gauge pressure gauge range can not be selected too much, but in order to ensure the measurement accuracy, the measured pressure is not less than the minimum pressure gauge full scale of 1/3 is appropriate. At the same time in order to extend the life of the elastic components to avoid elastic components due to long-term force is too large and permanent deformation, the upper limit of the pressure gauge should be higher than the maximum measured (range of 1/2 to 1/3), leaving margin.

Pressure gauge is a common measurement instrument, Digital Pressure Gauge widely used in various fields. It can visually show the pressure changes in the various processes, insight into the formation of conditions in the product or media process, monitoring the production process of the safety trends, Digital Pressure Gauge and through the automatic chain or sensor device to build a fast and reliable security, In order to prevent accidents, Digital Pressure Gauge protect the personal and property safety play an important role, known as the safety of the "eyes".

(1) The digital pressure gauge mounted on the boiler and pressure vessel, the maximum range (the scale limit on the dial) should be compatible with the working pressure of the equipment. Digital pressure gauge range is generally the equipment working pressure of 1.5 to 3 times, preferably 2 times. Digital Pressure Gauge If the choice of digital pressure gauge range is too large, due to the same precision digital pressure gauge, the greater the range, allowing the absolute value of the error and the greater the deviation of the naked eye observation, it will affect the accuracy of pressure readings; Digital pressure gauge range is too small, Digital Pressure Gauge the equipment working pressure is equal to or close to the digital pressure gauge scale limit, it will make the digital pressure gauge in the long-term elasticity of the largest deformation state, easy to produce permanent deformation, Digital Pressure Gauge causing digital pressure gauge error increase Large and reduced service life. In addition, the digital pressure gauge range is too small, in case of overpressure operation, the pointer over the maximum range close to zero, Digital Pressure Gauge leaving the operator illusion, Digital Pressure Gauge resulting in greater accidents. Therefore, the use of digital pressure gauge pressure range should not exceed the scale limit of 60 to 70%.

(2) The accuracy of the working digital pressure gauge is expressed as a percentage of the allowable error to the dial scale limit. Accuracy levels are generally marked on the dial, Digital Pressure Gauge the choice of digital pressure gauge, Digital Pressure Gauge the equipment should be based on the pressure level and the actual work needs to determine the accuracy.

(3) Diameter of the dial In order to allow the operator 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 is installed higher or away from the post, the dial diameter should be increased.

(4) digital pressure gauge for the measurement of the media if corrosive, Digital Pressure Gauge it must be based on the specific temperature of corrosive media, Digital Pressure Gauge concentration and other parameters to use different elastic components of materials, or fail to achieve the desired purpose.

(5) daily attention to the use of maintenance, Digital Pressure Gauge regular inspection, Digital Pressure Gauge cleaning and use the record.

(6) digital pressure gauge general test cycle for six months. Mandatory test is to protect the digital pressure gauge technical performance is reliable, Digital Pressure Gauge the amount of accurate delivery, effective guarantee of safe production of legal measures.
