- Q:What are the main technical parameters in the selection of pressure gauges? Thanks
- The selection principle is as follows:TypeThe selection of instrument type must meet the requirement of process production. For example, whether remote automatic recording or alarm; by nature side medium (such as the temperature of the measured medium height, viscosity, corrosive, flammable and explosive, dirt etc.) whether to put forward special requirements on the instrumentation, on-site environmental conditions (such as temperature, humidity, magnetic field strength and the vibration of the instrument) type etc.. Therefore, according to the requirements of the process, the correct selection of instrument type is an important prerequisite to ensure the normal operation of the instrument and safety in production.Two, measuring rangeAccording to the maximum and minimum values of the measured parameters, the upper and lower limits of the instrument can be calculated, and the measuring range of the instrument can not be directly taken as the measuring range of the instrument. When we select the upper limit of the scale of the instrument, we should select it in the standard series stipulated by the state. China's pressure gauge measurement range standard series are: -0.1-0.06,0.15; 0-1,1.6,2.5,4,6,10X10 "MPa" (where n is a natural integer. Can be positive or negative).Three, accuracy levelAccording to the maximum absolute error permitted by the process and the best range of the selected instrument, the maximum reference error allowed by the instrument is calculated, and the accuracy of the instrument is determined in the precision grade specified by the state. Generally speaking, the more sophisticated the instrument is, the more accurate and reliable the measurement result is. But you can not believe that the higher the accuracy of the instrument used, because the more sophisticated instruments, the more expensive the general price, the more difficult to operate and maintenance.
- Q:We use seismic pressure gauge oil, do not know how to come back. Trouble master solution
- Generally do not recommend their refueling. First of all, to check that the oil leak there, only the oil spill point can be solved again, do not solve, plus the leak. Say you add what kind of oil, general manufacturers have silicone oil (silicone oil has a variety of specifications), some glycerin, if two kinds of oil mix is more trouble, affect observation pressure. It is recommended to be returned to the manufacturer for repair.
- Q:How big is the thread type of the y-60 pressure gauge?
- The thread of the gauge does not specify how large it is. Recommendations: use the amount of the nominal diameter of the thread, and then measure its pitch, to determine the size and specifications of the thread, there is no understanding, please ask. Hope to be of help to you!
- Q:Vibration proof pressure gauge precision grade 1.6 and 1.5 difference
- The accuracy level of a pressure meter refers to the percentage of the allowable error of the pressure gauge to the full scaleFor example, a pressure gauge full scale is 100Mpa, the accuracy level is 1.6, then its allowable error is 100Mpa * 1.6%= + 1.6Mpa., if the accuracy level is 1.5, then its allowable error is 100Mpa * 1.5%= + 1.5Mpa.According to the current national standard GB/T1226-2001, "general pressure table", the accuracy level is 1.6, the use of 1.5 pressure gauges allowed error by 1.6 levels, the accuracy level can not be changed
- Q:Where is the pressure gauge checked?
- The pressure gauge is checked by the quality and Technical Supervision Bureau's measurement test.
- Q:How do remote pressure gauges receive frequency conversion?
- This is unable to access and control the frequency converter. The remote pressure gauge (resistance output) should be adopted - PG control board or pressure controller (resistance input / voltage output) - frequency converter (selection frequency, external control / voltage input)
- Q:The pressure gauge is red, yellow and green to indicate the pressure. When the needle points to the green area, what does it mean?
- The pressure of the lift extinguisher is designed according to the maximum pressure of the storage tank. Work pressure is defined as the internal balance pressure of a fire extinguisher rated and filled 20 hours after being placed in the environment for 18 hours. The situation you describe is qualified. Domestic fire extinguishers generally pressure gauges are divided into three grades, both three colors. The pointer undervoltage condition in the red zone, in the middle of the green zone generally reach fire extinguishers work pressure, and in the yellow zone that is overpressure, each fire extinguisher has its own working pressure, pressure is too low will affect the use of.
- Q:The difference between yn and YTN pressure gauges
- Seismic pressure gauge models now there is no unified naming rules, general provisions are: Y: T: pressure gauge; spring tube; N: Seismic
- Q:What kind of oil is it in the oil filled pressure gauge?
- Pressure meter which is filled with glycerin or silicone oil, and other can not, the general manufacturers are full of glycerol, because glycerol is cheaper, but the temperature of glycerol is relatively large, good point is filled with silicone oil.
- Q:Set up a factory. May I ask what equipment you need to build a pressure gauge factory?
- Now the production of pressure gauge is very simple, a lot of accessories are available, mainly to check the pressure gauge equipment, these devices do you need to see how much precision pressure gauge, decided to choose what equipment, equipment is not expensive. Plus, I can give you some advice
