Product Description:

Main function:  

l  This series machines are mainly designed for tension, compression, bending and shearing test of metal materials and meet with the requirements of GB/T228-2002”Metallic materials-Tensile testing at ambient temperature”.

l  This machine is also used for compression and bending test of nonmetal materials, such as cement, concrete and so on.

l  Equipped with special auxiliaries, it can be used for mechanical property testing of fastener, wire rope and components.

l  They are perfect testing instrument for project quality testing section, universities and colleges, research institution and industrial and mining enterprise.

Product features:

l  Host machine consults foreign technique, it has compact structure and a rational layout, significantly reduces the overall height comparing the oil cylinder overhead.

l  The machine owns hydraulic pressure sensor, which is with strong  impact and long-life. Adjust the test space by turbine structure of mobile beam does not need  rotation of screw when adjusting test space compacting the transmitting of chain. It makes complete separation between transmitting and postioning system, ensures the up and down jaws coaxial and the mainframe durable. Unique structure  of screw gap eliminating can guarantee the continuity of the load test.

l   Test data uses Access database management, which is powerful and convenient.

l   Resered data interface can connect with the network directly and share resources.

l   Independent hydraulic clamping structure can guarantee the reliability of the system; it will not hurt person for falling and ensure the safety of test personnel.

Q:Could you tell me why oxygen cylinders require two pressure gauges?
It shows two pressures, 1 side pressure and 2 side pressure, or the pressure before the valve and the working pressure after the valve.
Q:Is the ordinary pressure gauge oil resistant and vacuum resistant?
The use of pressure gauges should be chosen according to the specific working conditions.
Q:What is the difference between 380V and 220V electric contact pressure gauge?
380 of the voltage can kill people, and 280 of the voltage can make the whole body numb
Q:Where is the safety valve and pressure gauge for the gas tank?
Units with inspection qualification can be identified.
Q:How to connect the household air conditioner pressure gauge?
Before adding snow to open air conditioning, after the external machine started, the table connected to air conditioning gas nozzle (to receive a relatively thick that housekeeper, air-conditioning pressure in general 2.8MPA
Q:The difference and relation between the electric contact pressure gauge and the remote pressure gauge
The use of the two is different. One is used to control the other, and the other is to send the signal to the farther end of the monitor.The electric contact pressure gauge consists of measuring system, indicating system, magnetic auxiliary contact device, shell, adjusting device and junction box (plug seat), etc.. The working principle of electric contact pressure gauge is spring pipe in the measuring system under the action of the pressure of the measured medium based on the force generated by the end of spring pipe corresponding elastic deformation displacement transmission rod through a gear transmission mechanism with the help and amplification by the fixed gear instructions (along with contact) by the measured value indicated in the table. At the same time, when the contact and set on the pointer (upper or lower) contact (break or close) instantaneous, resulting in the circuit control system can be switched on or off in order to achieve the purpose of automatic control and alarm.The remote pressure gauge is suitable for measuring the pressure of liquid, steam and gas which can not corrode the steel and copper alloy. Because the resistance transmission pressure gauge is arranged inside the sliding line resistance transmitter, so the measured values of two meters on electricity to far away from the measurement, in order to realize centralized monitoring and remote control. In addition, the pressure gauge is capable of indicating pressure in place so as to facilitate on-site inspection.
Q:What's the cylinder pressure gauge for?
Measure cylinder pressure, use engine cylinder pressure value to judge engine problem
Q:Ytn10 and yn10 have these two types of pressure gauges? What do these two models stand for?
The 2 is the same north-south difference, not what the downstairs says
Q:What is the coefficient of error for the 2.5 grade pressure meter?
The calculation formula is that: the pressure of the table - pressure of the standard table / standard meter, the pressure *100% is less than or equal to 2.5% to be qualified.
Q:Pressure meter return error definition
According to JJG52-1999, Bourdon tube, general pressure gauge, pressure vacuum gauge and vacuum gauge,, return error:For the same test point, the difference between the indication value after tapping the watch case at the step-up (or step-down) and the buck (or boost) testThe return error is the absolute value
