- Measuring Range (air, N2): 5 x 10-9 ... 1000 mbar
- DN 35 CF Flange
- FRG700CF35
The gauge consists of two separate measurement systems (Pirani and cold cathode system) the signals of which are combined in such a way that one measurement signal is output. The Pirani measurement circuit is always on.
Over the whole measuring range, the measuring signal is output as a logarithm of the pressure.
The gauge is factory-calibrated. If used under different climatic conditions, through extreme temperatures, aging or contamination, and after exchanging the sensor, the characteristic curve can be offset and readjustment may become necessary.
The cold cathode measuring circuit, which is dominant for low pressures (<1×10-3mbar), is factory-calibrated and cannot be adjusted. By way of contrast, the Pirani measuring circuit can be adjusted. Any adjustment has a negligible effect on the pressure range between approx. 10-2mbar and 102mbar.
