Beishide Instruments’ Self – developed BSM – DS Module |
The self – developed BSM – DS module of Beishide Instruments integrates the sample cell, gas circuit, valve, pipeline, sensor, etc. There is no welding seam or seal ring, and the gas circuit connection is seamless. The vacuum degree of the whole system is improved by more than 90%, completely eliminating the leakage point. The overall system leak rate is less than 10 – 10 Pa·m³/s, improving the stability and reliability of the instrument. The gas circuit part of the system is integrally modularized for processing, greatly reducing the failure rate and improving the instrument stability. |
| Sample Loading | Import dual – port pressure sensor, segmented testing: 0 – 100Torr, or 1 – 1000Torr; testing accuracy error < ± 0.15%; Large – pore P0 has real – time testing function, making P0 measurement more accurate at the critical point.
(Patent Name: The analyzer of static volumetric method and pore size distribution. Patent No.: ZL20121020136959.X) |
| Degassing Station | Combined with Beishide’s self – developed vortex – type vacuum – pumping physical anti – pollution device, it can completely eliminate sample pollution during the vacuum – pumping process under the current of the existing gas, improving the vacuum – pumping efficiency and shortening the vacuum – pumping time.
(Patent Name: The physical anti – pollution device for vacuum – pumping station. Patent No.: ZL201620714986.3) |
| Vacuum System | The instrument is equipped with 2 sets of independent vacuum systems, namely, the degassing system and the analysis system are independent of each other, avoiding cross – contamination of the vacuum system. |
| Self – intelligent Detection | Advanced self – intelligent detection process, which can determine whether the sample tube is installed properly, whether the sample tube is tightened, and whether there is air leakage.
