| Abstract: | Pirani vacuum gauge and thermal couple vacuum gauge are rather suitable for measurement of vacuum in the interlayer of low-temperature thermal-insulated vessel,and currently the use of thermal couple vacuum gauge is relatively wider.From the comparison of measurement range,measurement precision,measurement temperature,interchangeability,remote monitor,leakage detection capacity and performance/price ratio of Pirani vacuum gauge and thermal couple vacuum gauge,a conclusion is obtained that Pirani vacuum gauge is more suitable for measurement of vacuum in the interlayer of low-temperature thermal-insulated vessel.Finally,technical parameters of several typical abroad commercial Pirani vacuum gauges and thermal couple vacuum gauges are listed. |
