- Q: What kind of oil is it in the oil filled pressure gauge?
- Don't talk nonsense! What you said is the general vibration proof pressure gauge, silicone oil filling. Other oils do not work
- Q: How does the fire pump pressure meter work?
- Imagine a floor of 3 meters, the 27 floor is 81 meters, so at least 81 meters to provide water pump pressure + atmospheric pressure, converted to 9.8*81*1000pa+1.01*100000pa=0.8938Mpa
- Q: How many degrees above is the high temperature pressure gauge?
- The use of environmental conditions: -40~200 degrees (YTH), relative humidity is not greater than 85%Effect of temperature: when the temperature deviates from 20 + 5 DEG C, the additional error of temperature is not more than 0.4%/10 degrees centigrade
- Q: How is the pressure gauge ABC divided?
- Instrument certification according to the location of the importance of varying degrees, generally divided into a, B, C three grades.A class is generally used in pressure control strict locations, requiring accurate instructions, is the focus of monitoring instruments, usually for an annual or semiannual inspection;Class B is generally used at locations where pressure control is more stringent and requires more accurate instructions. It is a general monitoring instrument, usually tested annually or two years;Class C is generally used in places where the pressure control is not strict and can be used as a reference value. It is a non monitoring instrument, usually tested for many years or replaced after failure;
- Q: What are the requirements of the gas pressure test for the pressure gauge?
- The maximum pressure shall not exceed the upper limit of the pressure gauge, preferably at the 2/3 position, and the measurement accuracy is relatively high. If the production needs to be calibrated by the technical measurement Institute, the validity shall be used within the period of validity. The watch list is better. The dial is larger. It looks clearer.
- Q: What are the precision grades of precision pressure gauges in our country?
- According to the JJG49-1999 spring tube precision pressure gauge and vacuum meter verification regulation, the accuracy degree of the pointer precision pressure gauge is:0.6, 0.4, 0.25, 0.1, 0.06
- Q: Can you use the precision pressure gauge of level 0.25, measuring range (0~10) and MPa to verify the general pressure gauge of level 1, measuring range (0~6) MPa? Why?
- Yes, measurement pressure gauge inspection requirements, standard table accuracy requirements greater than or equal to 4 times
- Q: How do you use this? How about two pointers? Don't use that kind of book. It's just as the saying goes, "take it step by step, how to use it. Thank you."!!!
- Blue red yellow high, connected with a low voltage, connected with vacuum pump, blue red switch full open, vacuum pump work for 10 minutes, then the blue red switch closed, wait 10 minutes, see the table pointer has no change, no change can add refrigerant, the refrigerant pipe connecting the first yellow bottle. Che Zifa, the cold medium, yellow head spin open air open blue switch, will be added, such as pointer does not move, turn off the blue switch, air conditioning, open blue switch, with a good bottle, then turn off the blue switch, change the refrigerant, then how much should be.! The red tube switch is always closed! Remember!
- Q: Working principle of electric contact pressure gauge
- The work principle is very simpleIt uses sliding resistors to control the switchThe current signal is outgoing
- Q: What is the maximum allowable error of a precision pressure gauge of 0.4? How to calculate?
- The accuracy level of a pressure gauge is divided by the percentage of its allowable error to the dial scale value, and the greater the accuracy grade, the greater the allowable error limit for the dial scale. The greater the measuring range of the pressure gauge, the same accuracy level of the pressure gauge, the absolute value of the pressure measurement it allows, the greater the error.Often use the pressure gauge diameter of 60 precision grade 2.5, dial diameter phi 100/150 accuracy of 1.6, level 1, diaphragm pressure meter accuracy is 2.5 grade, precision pressure meter accuracy: 0.4, 0.25.Allowable error of pressure gauge = range X (+ precision level)Example: the error rating of a pressure gauge is 0.4, and the range is 1MpaAllowable error of pressure meter = range X (+ precision level) =1Mpa * + 0.4%= + 0.004Mpa
