Q:Can the pressure meter read on the computer?
This one is ok. With a CWY series of digital watches, in a pressure source, coupled with the computer on it. Provide pressure with a pressure source, connect a digital meter to 485, and then connect to the computer. On the computer, you can read directly the pressure values for each point of the pressure. On the computer will directly generate reports, and finally print out the data directly with the computer just fine. Our shipyard is used Shaanxi Chuangwei this equipment. Very convenient! Increase of efficiency!
Q:What's the difference between a pressure gauge and a negative pressure meter?
A negative pressure meter is also a pressure gauge. It is only used to measure negative pressure. Negative pressure is relative to standard atmospheric pressure.
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:The pressure gauge is red, yellow and green to indicate the pressure. When the needle points to the green area, what does it mean?
It means normal pressure, yellow means high pressure, red means low pressure and can't be used.
Q:What does the condensing pressure gauge in the refrigeration system measure?
Measuring the condensing pressure, this pressure is determined by the temperature of the refrigerant saturation state your condenser, the heat transfer ability of saturated refrigerant temperature by heating your heat exchanger (area, heat transfer coefficient and the temperature of the cooling medium is decided)
Q:What's the meaning of diaphragm pressure gauge YTP-100?
Refers to the internal diameter of the pressure gauge 100mm
Q:The role of a pressure gauge
As the name suggests, it is to measure the pressure, welding need to ensure adequate flow of gas protection, sufficient flow is the premise of sufficient pressure in the tank, pressure gauge is to show the pressure inside the tank is enough
Q:What does the pressure gauge 1% mean?
Pressure gauge accuracy of 1%, that is, the standard accuracy level of 1 pressure gauges.A pressure gauge with a rating of 1, indicating that the measuring range of the pressure meter is 1% of the full range.That is, 1MPa pressure gauge, the accuracy level is 1, that is to say, this value error is + 0.01MPa.5MPa pressure gauge, accuracy class is 1, that is to say, this value error is + 0.05MPa.If the accuracy level is 1.6, the measurement error is + 1.6%.1MPa pressure gauge, the accuracy level is 1.6, the value of this error is + 0.016MPa.
Q:Is the gauge thread metric or English?
What thread do you want to thread on your request?. Often used in metric systems
Q:What's the difference between the pressure gauge and the bellows pressure gauge?
I am engaged in the sale of this product, and I will answer your question. Bellows gauges are used as sensitive elements for measuring micro pressure. Measurement of corrosion resistance of copper alloys, no explosion of dangerous gases, micro pressure and negative pressure, widely used in boiler ventilation, gas pipelines, combustion equipment and other similar equipment. Stainless steel film box, pressure gauge according to the pressure system and shell are made of stainless steel material. It is applied to the measurement of micro pressure and negative pressure of various gas mediums in the process of high corrosion resistance. The stainless steel film box pressure gauge is developed with reference to the structural characteristics of the original film box pressure gauge and a micro manometer with corrosion resistance is developed. Applied to the boiler ventilation and gas pipelines and other equipment, in the process of corrosion resistance requirements of high pressure measurement of various gas medium micro pressure and negative pressure. Accuracy: measurement range: 2.5 (kPa) from 0 to 4; 0 to 6; 0 to 10; 0 to 16; 0 to 25; 0 to 40; 0 to 60; -4 ~ 0; -6 ~ 0; -10 ~ 0; -16 ~ 0; -25 ~ 0; -40 ~ -2 ~ 0; 2; -3 ~ 3; -5 ~ 5; -8 ~ 8; -12 ~ 12 -20 ~ 20 -30~30; the use of environmental conditions: -25 to 55 degrees Celsius, relative humidity is not more than 80% anti vibration working environment: V - H - 3 weight: 0.5kg
