Equipped with special auxiliaries, it can be used for bending resistant test of building materials and compression resistant test of red bricks. We can evaluate result parameters stated in related standards. They are perfect testing instrument for building project detection department, quality testing section, universities and colleges, research institution and industrial and mining enterprise.
Ⅱ、Product features
1、Host machine is with double column type, which make the conformation compact and arrangement reasonable.
2、Adopt precise electro-hydraulic servo proportional valve. The speed is fast and the controlling accuracy is high.
3、Mechanic limit pistons protection assures the safety of testing.

- Q: What does the water pressure meter MPa stand for?
- MPa is a unit of pressure. 1MPa (Zhao Pa) = 10 kg / cm2.
- Q: How do remote pressure gauges receive frequency conversion?
- Frequency converter 10V, VF, GND point is the voltage control frequency of external contacts, is not directly connected to other signals, and can not be defined as other functions, in addition to voltage signals. As for the remote pressure gauge, one is divided into upper and lower limit, switch signal output, (also an instant signal, leaving the lower limit pointer is disconnected, cannot keep) called electric contact pressure gauge; there is no so-called resistance output, the upper and lower limit, through the pressure controller or by the PG board needs to transform into a voltage or current signal to control the frequency converter. Therefore, the remote pressure gauge can not be directly in the inverter 10V, VF, GND points, you need to control the inverter through some means.
- Q: The composition of the pressure gauge?
- The pressure gauge mainly has following parts and components: joint, spring tube, seal piece, movement, connecting rod, dial, pointer, lining ring, watchcase, watch glass, cover ring. The key components are joint, spring tube and core.
- Q: What's the effect of the rubber plug at the top of the shock gauge? What's the effect of not cutting off?
- There are 2 main functions of rubber blockage:1 prevent the transit of seismic oil leakage.2 prevent during use, due to excessive vibration proof pressure gauge and oil leakage, pollution equipment.After the rubber plug with a pressure gauge must be installed to cut the U-turn, ease pressure generated during the operation of cavity pressure in high temperature environment, vibration, seismic oil preheating after expansion will produce cavity pressure, so the use must be cut off.
- Q: How do you contact the pressure meter to the pump control box?
- The electric contact pressure gauge has upper limit and lower limit contact (common midpoint). The lower contact (less water start, parallel contactor normally open contact retention) connected to the pump contactor coil; the upper contact (water full stop) connected to intermediate relay coil, the normally closed contact string into the pump contactor coil circuit of the intermediate relay action, disconnect contactor coil power source. If the contactor is large, then the lower limit contact will be amplified by another relay.
- Q: It is better to explain in principle what parts are not resistant to heat What happens if you measure a high temperature medium? Is it just inaccurate or will there be parts damage?
- The general pressure gauge because of environmental requirements, material control, cost of processing technology is adopted for the purpose of different force used in high temperature environments can lead to measurement error has been damaged if the temperature exceeds the pressure gauge, pressure gauge allows too large range of possible accidents.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.The pressure gauge through the sensitive element in the table (Bourdon tube, bellows, bellows) of the elastic deformation, then the conversion mechanism of table movement will transfer to the pointer pressure distortion caused by pointer rotation to show pressure.
- 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: The structure and working principle of the membrane box of the membrane pressure gauge?
- The free end of the film box is divided into two parts, and the lower end is an air inlet. Then the upper end of the film box is used for driving the connecting rod to work
- Q: If the pressure gauge of the fire extinguisher is damaged and the interface of the pressure gauge is broken, will the fire extinguisher leak?
- The bottle body collision, deformation and cracking damage of nozzle nozzle is not to use the fire extinguisher pressure gauge in the red zone under voltage, need maintenance, seal damaged also need maintenance, depression
- Q: What's in, Hg, VAC on the R134 air conditioner pressure gauge?
- R134: refrigerant for automotive air conditioning.In Hg: Inch mercury column, pressure unit. 1In Hg=25.33 mm HgVAC:VAC - vacuum warning lights, often used in cars
