Description Dead Weight Vacuum Gauge Tester :
YS-2.5/YS-0.6 is mainly used to test precision pressure gauge that with pressure range from -0.1 ~ 0.25 MPa to 0.1 ~ 0.6 MPa, and within accuracy of 0.1, 0.16, 0.25 and 0.4 class.Its accuracy is 0.02 or 0.05, working medium is gas.
Working principle and basic structure Dead Weight Vacuum Gauge Tester
How it works: pressure systems and processing on the weight of the weight of the piston effective area of the piston on the piston as standard pressure generated by the pipeline of the working medium, the pressure is transmitted to the test gauge .
Structural principle shown in Figure 1. In the gauge base piston systems, spinner and five valves.
When measuring pressure, the piston system should be in the position shown, valve 1 mouth contact compression pressure source (YS2.5 type maximum pressure ≥0.25MPa, but more than 0.40MPa, should be connected to the decompression device; YS0.6 type Maximum pressure ≥0.6MPa) or hand pump pressurized air, gas enters the spinner, and then communicates with the meter under test through the valve 3, through valve 4 acting surface in the lower end of the piston, exerting pressure on the valve 5 through oil cup surface, to lubricate and seal at the piston.
Figure 1
When measuring the vacuum, the piston system should be in front of 180 ° rotation around the horizontal axis and locking valve connected to a vacuum pump connected to the mouth 1 through the pipe line and the measured meter turned and acting on the piston end face, and you should close the valve 5 open the oil cup cover and the atmosphere, in order to get to zero.
Instrument piston rod bearing system and knurled nut weight 0.051Kg, remaining piston lever for equal weight 0.051Kg, need to remove the load-bearing rod measured 0.005MPa this point and knurled nut.
