Vacuum Gauge
- - Displacement speed(60Hz) :
- - Ultimate Pressure :
Pirani vacuump gauge (VSPI-3002)
Model : VSPI-3002
0.001 to 10 Torr Range
If Pirani gauge's principle supplies constant voltage to sensor's filament that is established to vacuum chamber, because resistance value according to change of pressure of vacuum changes, it is principle to convert by pressure of vacuum change of flowing current to sensor.
Improved accuracy about sensor using 10bit AD converter.
Improved interior corrosion and oxidation by Sensor filament's gold coating.
improved voltage stability and authoritativeness by SMPS power supply type.
External appearance is elegant, and added Analog output DC 0 ~ 5 V by FND display type
