Absolute Pressure 1000...100 mbar to 1 x 10-3 mbar, 750...75 Torr to 1 x 10-3 Torr
The VSP841 and VSP842 Pirani half bridges measure 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.
Benefits
Economical Pirani sensor
Good long time stability
Durable sensor, elastic helix filament
Filament protected from condensing solvents by a metal screen
Sensor pre-adjusted
Extremely small sensor volume
Screwable, electric connector
Proposal for evaluation circuit available on request
Typical Applications
Monitoring of vacuum insulations
Appliances with integrated electronics for regulation and evaluation
Apparatus engineering
Chemical process engineering
Analysis instruments
Freeze drying
Concentrators
