- 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: What does "MPa" on the pressure gauge mean?
- The MPa (Zhao Pa) on the pressure gauge is the unit of pressure,0.1 MPa =1 kg / cm2.
- Q: Function of electric contact pressure gauge
- Function of electric contact pressure gauge:The utility model is used for measuring the positive and negative pressure of the gas and liquid medium which does not corrode copper and copper alloy, and sends out signals when the pressure reaches a predetermined value, and the control circuit is switched on to achieve the purpose of automatic control of the alarm.Electrical contact signal pin in electric contact pressure gauge device, a permanent magnet can be adjusted, can increase the contact force, speed up the contact action, so that the contact reliability, eliminating the arc, can effectively avoid the instrument working environment due to frequent vibration or medium pressure pulsation caused by contact off. Therefore, the electric contact pressure gauge has the advantages of reliable operation, long service life and large power of the contact switch.
- Q: I want to use a frequency converter and a remote pressure gauge to control a submersible pump, using the on-off control, constant pressure water supply, how to connect and set up
- I think you may be wrong! More (money, easy) scheme is using 1 transmission pressure gauge + inverter, constant pressure control. But not switch control. Control is continuous.The only output switch contact transmission pressure gauge is the electric contact pressure gauge. Inside a rheostat, with the change of pressure, sliding rheostat output resistance change. But it should be noted that this watch is certainly three line connection (don't understand NO/NC/COM).Like ABB, ACS510 series and so on, you can access to the X1 2,3,4 terminal, so as to achieve constant pressure control, specifically, you have to look at your inverter manual
- 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: Band sawing machines sometimes fail to rise, sometimes very slowly, and sometimes pressure gauges have no pressure
- For many reasons, there may be oil change or insert the owl problem, to find the best manufacturers see sawing machine.
- Q: What is a pressure gauge and how to make it?
- An instrument with an elastic element as a sensing element to measure and indicate higher than the ambient pressure.
- Q: Is the pressure gauge also a pressure sensor?
- Yes, and displayed through the dial
- Q: How to choose a pressure gauge?
- A digital or a pointer is a manometerWorking environment, vibration proof, stainless steel...Accuracy classMeasuring range, how many MPA?Dial diameter
- Q: Where does the meter check the pressure gauge? How long is the training time?.
- Routine test items and regulations of pressure gauges1, appearance inspection1.1 assembly of pressure gauge parts should be firm and free of looseness.1.2 the newly made pressure gauge should be even and smooth with no obvious stripping.1.3 pressure gauge should have safety hole, safety hole must have dust-proof device. (media not allowed to be spilled outside the pressure gauge outside the table)1.4 pressure gauge on the indexing disc should have the following marks, manufacturing units or product name; trademark; units of measurement and digital measurement equipment manufacturing license mark and number, vacuum gauge should be "-" or "negative", the level of accuracy of the serial number.1.5 readings shall be colorless and transparent and shall not contain defects that interfere with readings. The indexing plate shall be level and smooth with distinct marks.The 1.6 pointer shall cover the minimum length of the index line 1/3~2/3, and the width of the pointer indicating end shall not be greater than the width of the graduation line.1.7 accuracy levels are 1, 1.6, 2.5, 4.1.8 zero, with a check of the gauge pin, without pressure or vacuum, the pointer should be close to the stop pin, "indented" should not exceed the allowable error value specified in Table 1, the pressure gauge without stop pin, without pressure or vacuum, corresponding to the zero mark pointer, zero mark should be 2 times the allowable error absolute value specified in table 1.
