Passive Pirani Gauge
(1000 - 5x10⁻⁴ mbar)

Body Material

Edwards Passive Pirani Gauge Sensors are available in 3 models. The PRG20K-NW16 Al is improved temperature compensation, the PRG20K-DN16CF SS is overpressure resistant and PRG20CF-NW16 SS is well suited for corrosive processes and water vapour atmospheres.
These passive gauges offer a solution for measuring pressure in a wide range of applications, from UHV systems to process industries or wherever the use of an active gauge is not possible e.g. Cyclotrons and thermal conductivity technology according to Pirani.
