SAI Offers Compact Solid State Electronics Digital High Pressure Pirani Guage with Provision of connecting 2 Nos. Sensors to read Vacuum from . It is Factory Calibrated for reliable and repeatable reading, Pressure indications, Excellent Zero Stability and with/without set point controller and Modular Design.
Pirani Guage works on Principle of wheat stone Bridge. Change of pressure in vacuum system brings about fall or rise in the no. of gas molecules which brings resistance change into electrically heated filament in the system which forms one arm of wheat stone bridge.
This Pirani Gauge instrument with two sensors having wide range of applications, in high vacuum systems where one sensor is used to measure backing vacuum and the other sensor can be used for measuring high vacuum. Pirani Gauge instruments can be used in high vacuum systems, coating units, sputtering units, and many other applications where vacuum to be measured in the range of 0.000 to 0.001 m.bar.
