- Q: For example, a 1.6 mpa. How do you measure it?!
- A high, medium, and low end pressure gauge shall be a three position contact type control pressure meter. If no signs are available, you can use either the ohmmeter or the buzzer test of the meter. Use the pencil first low limit hands to contact with the actual pressure gauge contact is closed, with a multimeter measuring three end exchange both ends of the middle and low end, the rest is high, then closed contact separately, the high pressure closed with the actual pointer to pointer, and then test interoperability both ends of the middle and high, so you can points out.
- Q: What is a negative pressure gauge?
- The negative pressure gauge should be another name for the vacuum meterVacuum meter: Instrument Based on atmospheric pressure for measuring less than atmospheric pressure.
- Q: What is the state of the warranty period for the ordinary pressure gauge?
- The pressure gauges are calibrated once every 6 months,Wuxi Hui Hua Instrument Technology Department
- 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: What are the diaphragm materials for the diaphragm pressure gauge?
- The biggest advantage of diaphragm pressure gauge is that it can select different diaphragm material according to different corrosion medium, so as to achieve the best corrosion resistance.At present, the diaphragm materials are commonly used tin bronze, SU316 stainless steel, titanium, tantalum, Monel, Hastelloy, PTFE etc..In the use of diaphragm pressure gauge, in addition to correctly select its structure form, the more important thing is to reasonably select the diaphragm diaphragm material. The so-called reasonable is to consider both its corrosion resistance, but also to consider the economy.For example, tantalum sheet and Hastelloy alloy have excellent corrosion resistance, but they are expensive and are only used in corrosive environments where other inexpensive materials are not suitable.
- Q: Why is the manifold pressure gauge called the manifold pressure gauge, not the air conditioning pressure gauge group?
- The manifold pressure gauge is called the manifold pressure gauge because the pressure gauge is mounted on the manifold. Detection of air conditioning system pressure gauge is more, such as the evaporator refrigerant pressure, working pressure of the condenser, cooling water inlet and outlet pressure, cooling water inlet and outlet pressure, circulating pump inlet and outlet pressure, air-conditioning pipe pressure differential pressure, oil pressure, oil separation pressure, if called the gauge group is not specific determine what part of the work pressure, can not determine the various parts of the system working pressure is normal.
- Q: The greater the accuracy of a pressure gauge, the higher or lower the accuracy of the measurement, or the difference between the two
- 2.5 represents the accuracy of the maximum range of 2.5%, 1.5, 1.5%, so the larger the number, the lower the relative accuracy, when it is necessary to pay attention to its maximum range is how much
- Q: What is the calibration cycle for the pressure gauge / thermometer / flowmeter? Is there a standard to check?
- Used as an enterprise, usually for one year unless required.
- Q: What are the common measuring ranges of pressure gauges?
- 0.25mp, 0.6mp, 1.0mp, 1.6mp, 2.0MP, 2.5MP and so on. In order to ensure that the elastic element can work reliably in the safety range of the elastic deformation, the pressure gauge range is selected not only according to the measured pressure, but also should consider the measured pressure change rate, the range need to leave enough room for. When measuring the steady pressure, the maximum working pressure shall not exceed 2/3 of the measuring range; the pulsating pressure shall be measured; the maximum working pressure shall not exceed 1/2 of the measuring range; when measuring the high pressure, the maximum working pressure shall not exceed the 3/5 of the measuring range. In order to ensure the accuracy of measurement, the minimum operating pressure should not be less than 1/3 of the measuring range. According to this principle, according to the measured maximum pressure to calculate a value, from the pressure gauge product catalog select a little larger than the measurement range.The pressure gauge is divided into vacuum meter, pressure vacuum meter, micro pressure meter, low pressure meter, middle pressure meter and high voltage meter according to its measuring range. Used to measure the atmospheric pressure is less than the pressure value of the vacuum gauge; pressure vacuum gauge used to measure the atmospheric pressure is larger than the pressure value; micro pressure gauge for measuring the pressure value is less than 60000 Pa; low voltage meter for measuring 0~6MPa value of pressure; pressure meter for measuring 10~60MPa value of pressure; pressure gauge for measuring the pressure value of more than 100MPa.
- Q: How to choose a pressure gauge?
- The first is selected according to the type of environmental characteristics, such as whether the need of explosion-proof, and then select the range, the general scale selection principle is that the pointer under normal pressure, shown in the 2/3 position is appropriate, margin; according to the actual demand, choose the suitable range of precision; the interface is needless to say.
