vacuum sensors – hvs series

vacuum sensors – hvs series-大富豪官方网站

the hvs series is our vacuum sensing series. these miniature pirani-type vacuum sensors allow measurements in a pressure range from 1000 mbar (atmospheric pressure) down to 10-3 mbar (hvs 04), and 10 mbar down to 10-5 mbar resp. 10-6 mbar (hvs 03k resp. hvs 03g). they come in a small and robust to-39 or to-8 metal housing. assembling the hvs 04 and hvs 03g in a to-8 housing allows coverage of the full pressure range.
  • pirani measurement principle
