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
- very large pressure range 1000 mbar to 10-6 mbar
- small form factor to-39 or to-8
- robust metal housing
- high sensitivity
