VSP841 Passive Vacuum Sensor ● DN16KF

The VSP841 Pirani half bridges measures absolute pressure in the fine vacuum range. The robust heat conduction sensor is compact, pre-adjusted and temperature compensated.
It is suitable for controlled and passive bridge circuits and as sensor for monitoring of vacuum isolations, readout of measurements with 
VD84.
