3 Terms and Definitions
The following terms and definitions apply to this standard.
3.1
In the differential pressure sensor detects the pressure difference between the measured object and the reference material for the pressure-sensing element to determine whether there is leakage measured object size and leak rate
An instrument or device.
3.2 Reference material master
And the shape, material and volume of the same analyte and the leakage rate and the measured object can be neglected compared to the reference object.
3.3 Volume corrector
Through precise, small amount of change in volume, so that the leak detector generates a pressure difference of different devices.
4 classification, structure and basic parameters
4.1 Classification
Leak test pressure divided by.
a) Vacuum leak test pressure of less than 1 × 105Pa (gauge pressure range of -100kPa ~ 0kPa);
b) micro-pressure leak test pressure in the range of 1 × 105Pa ~ 1.5 × 105Pa (gauge pressure range of 0kPa ~ 50kPa);
c) a low pressure leak test pressure in the range of 1.5 × 105Pa ~ 3 × 105Pa (gauge pressure range of 50kPa ~ 200kPa);
d) the pressure leak test pressure in the range of 3 × 105Pa ~ 8 × 105Pa (gauge pressure range of 200kPa ~ 700kPa);
e) high-pressure leak test pressure is higher than 8 × 105Pa (gauge pressure greater than 700kPa).
4.2 Structure
Detection of analytes with general inflation port of the leak detector (the structure is shown in Figure 1). Unit detected no inflation port sealing components
Leak detector (the structure is shown in Figure 2).
