In production, stainless steel reactors usually work under pressure, so they are equipped with pressure gauges to indicate the pressure in the reactor. There are many kinds of pressure gauges on the reactor, including ordinary pressure gauge, ammonia pressure gauge, oxygen pressure gauge, electric contact pressure gauge, vibration resistant pressure gauge, pressure gauge with inspection pointer, etc. The selection of reactor pressure gauge should be based on the use requirements and specific situation.

 

In accordance with the technical conditions proposed in the production process, stainless steel reactor in line with the principle of economy, reasonable type, model, range, precision grade selection. The selection of pressure gauges is mainly considered in three aspects:


(1) According to the measured pressure, determine the instrument range. For the elastic stainless steel reactor pressure gauge, in order to ensure that the elastic element can work reliably within the safe range of elastic deformation, when selecting the range of stainless steel reactor pressure gauge, it must be considered to leave enough room. Generally, when the measured pressure is stable, the maximum pressure value should not exceed 3 / 4 of the full range; When the measured pressure fluctuates greatly, the maximum pressure should not exceed 2 / 3 of the full scale. In order to ensure the measurement accuracy, the measured pressure should not be less than 1 / 3 of the full range.

 

(2) The properties of the medium to be measured should be considered in the selection. Such as temperature, viscosity, corrosivity, dirt degree, inflammable and explosive, etc. Also consider the environmental conditions of the site, such as high temperature, corrosion, humidity, vibration, etc. In order to determine the type and model of stainless steel reactor pressure gauge.

 

(3) The accuracy of the instrument is determined according to the maximum measurement error allowed by the production. When selecting, the stainless steel reactor pressure gauge with low accuracy, low price and durable should be selected as far as possible under the condition of meeting the production requirements.

 

When customizing stainless steel reactor, the selection of stainless steel reactor pressure gauge can be based on the actual production situation.In accordance with the technical conditions proposed in the production process, stainless steel reactor in line with the principle of economy, reasonable type, model, range, precision grade selection. The selection of pressure gauges is mainly considered in three aspects.
