Vacuum Sensors
Vacuum Sensors - HVS Series
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 (HVS 03k). They come in a small and robust TO-39 or TO-8 metal housing. Assembling the HVS 04 and HVS 03k in a TO-8 housing allows coverage of the full pressure range.
Features and Benefits
- Pirani measurement principle
- Very large pressure range 1000 mbar to 10
-5 mbar
- Small form factor TO-39 or TO-8
- Robust metal housing
- High sensitivity
