The Heimann vacuum sensor HVS is a miniature Pirani-type sensor based on a heated resistor structure on a thin micromachined membrane. The sensor comes in a small, robust, TO type metal housing.
The sensor type HVS Vac03k shows a response U(p) typically ranging from 0 – 400 mV in the pressure range 1 mbar - 10-5 mbar. HVS Vac 04 can be used in the 1 - 1000 mbar range.
Two chips, Vac 03k together with Vac04, can be mounted in the same TO8 housing to make the HVS dual chip model - HVS Vac3k+Vav04. This allows for a wider measurement range by switching from Vac03k to Vac04.
