、Main functions
  WDS series are suitable for tensile, compression, bending,cutting shearing and tearing test of rubber peeling and tearing plastic, electrical wire and cable, composite, profiled bar, waterproof roll, etc. They are essential testing instruments for quality testing section, university and college, research institution and industrial and mining enterprise.
、Product features  
 This machine equips alternating servo motor for driving crossbeam and imported photoelectric encoder for displacement measure. The controller adopts flush type monolithic computer structure and is equipped multitask operating system and built-in powerful test control software, which includes the test system with measuring, controlling, calculating and saving functions.  This machine has the following performances: Automatically calculating stress, elongation rate, tensile strength and modulus of elasticity
;automatically preserving all of 16 groups testing data;automatically recording the value of extremal vertex, breakpoint, appointed value of force and elongation;testing result can be scanned by pages and printed;the third class purview management;real-time electronic clock, and automatically recording the testing date and time.

Q:Pressure gauge model Y100-1.6KPa
Contradiction between model and rangeModel is the ordinary pressure gauge (range 0~0.1~100MPa)The measuring range is the diaphragm pressure gauge (model YE-100, range 0~1~60kPa)There are two possibilities: 1, the ordinary pressure gauge Y-100, 0-1.6MPa; 2, membrane pressure gauge YE-100 0-1.6kPa.
Q:Cutting acetylene bottles on how there are 2 pressure gauges, which is an adjustable, adjustable number, and oxygen. Thank you!
There are two pressure gauges on the acetylene meter. One is a high pressure meter that measures the pressure in the bottle (i. e. the amount of acetylene in the bottle). Another piece of table is a low table, can be adjusted, which is cutting the required pressure, the pressure is related to the thickness of the plate according to the number ofAn oxygen meter is the same as an acetylene meter
Q:Is the 16 kilogram electric pressure gauge and the electric contact pressure meter the same?
The electric control meter is controlled by the electronic sensor switch, and the electric contact switch is controlled by the mechanical contact, and the mechanical point controls that when the current flows through, the arc is generated, and the contact of the starting point is not good, and the utility model is not used. Therefore, it is recommended to use the electronic pressure gauge.
Q:Function of electric contact pressure gauge
The instrument comprises a measuring system, an indicating system, an outer shell, a magnetic auxiliary electric contact device, an upper and lower adjusting device and a junction box. When the measured medium pressure through the guide part into the measuring element, in which the pressure produces the corresponding displacement measuring element free end through the connecting rod drives the gear transmission mechanism, resulting in the dial on indication of the measured medium pressure value. At the same time, the instrument pointer drives the upper and lower limit movable arm and the set pointer (upper and lower limit) contacts to be disconnected or closed, so that the control circuit can be switched off so as to achieve the purpose of automatic control or sending letters to alarm.In general, the instrument can be used for automatic control or transmitting alarm by measuring and controlling the pressure system of the medium (or relay), which is used in conjunction with the corresponding electrical appliances (such as relays, contactors, etc.).
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:Cutting acetylene bottles on how there are 2 pressure gauges, the general number of suitable adjustment
A high pressure is used to measure the acetylene pressure inside the tank (0~4MPa)A low pressure is used to measure the output pressure of acetylene (0~0.25MPa)How much is the general adjustment?
Q:What kind of oil is it in the oil filled pressure gauge?
Pressure meter which is filled with glycerin or silicone oil, and other can not, the general manufacturers are full of glycerol, because glycerol is cheaper, but the temperature of glycerol is relatively large, good point is filled with silicone oil.
Q:See others welding, found that there are two pressure gauges on the cylinder, one is 0-0.3 range as if, and the other is 0-4 range, ask why, is it safety considerations or other reasons? thank
0-0.3MP is a low pressure meter, which is an oxygen pressure reducer. It converts the high-pressure oxygen into a uniform low-pressure oxygen through the knob handle to supply welding or cutting. 0.3MP's pressure is very common.0- 4MP is a high pressure oxygen meter. The oxygen bottle allows 15MP gas to be filled. This is the gas left in the cylinder at present, 4MP. High pressure makes gas cylinders fill more gas.
Q:How about the model of seismic pressure gauge?
There is a general proof letter "N"
Q:How to choose the accuracy level of the standard pressure gauge when calibrating the industrial pressure meter with the standard pressure gauge? Can I use a stage 0.2, range 0 to 25MP?
The general election results table to use than the calibrated meter high a range check table, table 2.5 the pressure should be 4MPa, 25MPa a lot.
