Item Description

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 types HVS Vac03g and HVS Vac03k show 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 03g together with Vac04, can be mounted in the same TO8 housing to make the HVS dual chip model - HVS Vac3g+Vav04. This allows for a wider measurement range by switching from Vac03g to Vac04.

Select from the pull down menu above. Please contact our application team for other options or dual sensors.
