Q:The pressure gauge 0.1 stands for a few kilograms of pressure

The general pressure gauge 0.1 stands for "0.1Mpa", that is, 100000N/m2100000N can be converted into kg by itself.

Q:I have seen pressure gauges at the medical levelOne is the diaphragm pressure gauge with diaphragm at the sanitary levelOne is: wire head pressure gauge used in jacket heat onIs there a pressure gauge that is both sanitary and not diaphragm?

Diaphragm pressure gauge is suitable for measuring strong corrosion, high temperature, high viscosity, easily crystallized, and medium pressure solid suspensions and must avoid measuring medium directly into the universal pressure gauge and prevent sediment accumulation and easy cleaning.Sanitary pressure gauge is also a diaphragm, is a common pressure gauge and diaphragm separator composed of a system of diaphragm pressure gauge. The utility model has the advantages of quick and convenient assembly and disassembly, easy pollution, easy cleaning, safe and reliable safety, etc.. It can meet the requirement of pharmaceutical production quality standard (GMP). In the pharmaceutical, food, drinking water, water treatment and other industries, the instrument has a hygienic requirements of the process has been widely used.

Q:What is a pressure gauge and how to make it?

1. Pressure gaugeRefrigerant leakage is a common fault of air conditioning, refrigeration for dose adequacy of detection system, used to the pressure gauge, pressure gauge is a commonly used detection tool of freon refrigeration system, its shell diameter from 60mm to 250mm, a variety of specifications, suitable for air conditioner refrigeration system using a vacuum pressure gauge range to -0.1mpa 2.5MPa, as shown in figure 2-33,The pressure gauge and three way valve repair often supporting the use of clockwise three pass valve knob can make the valve repair, narrow hole, knob clockwise end, corresponding with the outdoor unit piping gas cut off, counterclockwise rotation knob, valve hole expansion, corresponding piping and outdoor group gas conduction, refrigeration system and the three way valve repair pressure gauge has been conducted, has nothing to do with the knob, together with three pass valve repair switch, can realize vacuum pumping, refrigerant filling and test pressure of the refrigeration system, etc..

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

Q:How to use the car fuel pressure gauge?

Usage method：(1) start the engine and switch to the normal operating temperature, turn off the engine, and then remove all the spark plugs when the engine is stopped;(2) the solar term valve is fully opened, the pressure gauge connecting head is pressed on the spark plug on;(3) use a motor to rotate the engine at 100 150r / min speed for 3 to 5 seconds. At this point, the pointer on the instrument will gradually rise, to a certain value that will stop, at this point the indicator value is the compression pressure of the cylinder;(4) press the button to make the pointer zero;(5) repeat the measurement 2~3 times according to the above procedures to improve the measurement accuracy.(6) general car cylinder pressure >0.9MPa and delta <8% (pressure of each cylinder, gasoline engine cylinder average pressure of not more than 8%).If the measured value is smaller than the specified value, and the intake system is normal, it can show that the cylinder and piston, cylinder head leakage, the original cylinder, piston, valve, piston ring wear, ablation and other undesirable situation. If the measured value is greater than the specified value, and the intake and exhaust system is normal, the possible cause is the serious carbon deposition in the combustion chamber.

Q:Is the pressure meter the same as the pressure meter?

Pressure gauge: only one pressure value is measuredPressure differential: measure two pressure values, and calculate the pressure differenceDissimilarity1, the number of pointers is not the same2, sensor number is not the same3, the structure is not the same

Q:The hydraulic machine of the electric contact pressure gauge old bad, an oil spill, and two pointer does not return, I personally think that is the quality of table or hydraulic diaphragm was too frequent starting impact times too much damage, used in hydraulic machine is not reliable electric contact pressure gauge. Present your valuable comments or suggestions, and Solutions

The hydraulic machine out of pressure is not too stable, this causes the pressure gauge frequently in that swing, and the electric contact pressure gauge used in pressure fluctuation environment is little use to play its normal life

Q:Does the pressure meter belong to the field of mechanics?

Scope of inspection instruments category

Q:First, the water pump remote pressure gauge in the pipe without water, whether the pointer should refer to 0Second, when the inverter is not bad and does not work, whether the table of sliding resistance is bad, so that the frequency converter can not be induced without action. Thank you for your advice.

The pressure gauge (English Name: pressure gauge) refers to the elastic element as the sensitive element, measuring and indicating higher than ambient pressure meter is widely used, it almost all the industrial processes and scientific research. In the heat pipe network, oil and gas transmission, water supply system, vehicle repair and maintenance shop, and other fields can be seen everywhere. Especially in the control and measurement process, because the elastic sensitive element of mechanical pressure gauge has the characteristics of high mechanical strength and convenient production, the mechanical pressure gauge is widely used.

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
