Pfeiffer Vacuum PKR 360 Series Pirani/Cold Cathode Gauge

The Compact FullRange® Gauges PKR 360 and PKR 361 have been designed for vacuum measurement of gases in the pressure range of 1×10-9 to 1000 mbar. They must not be used for measuring flammable or combustible gases in mixtures containing oxidants (e.g. atmospheric oxygen) within the explosion range. They are intended for operation in connection with a Pfeiffer Vacuum measurement unit for Compact Gauges or with another suitable controller.

The gauge consists of two separate measuring systems (the Pirani and the cold cathode system according to the inverted
magnetron principle). They are combined in such a way that for the user, they behave like one measuring system. Over the whole measurement range, the measuring signal is output as a logarithm of the pressure.
