LEYBOLD COMBIVAC CM 31 - 1.4 Equipment

to the prevailing pressure. A new sensor design permits
safe and reliable measurement operation of this „inver-
ted Penning“ in the pressure range between 1·10
-9
mbar
and 1·10
-2
mbar.This sensor is available fitted with either
a KF or a CF flange. The special alloy used for the
magnet permits bakeing out of the sensor (with CF flan-
ge) up to 250 °C without having to remove the magnet.
The rugged electrodes may be simply taken out and ins-
erted again for cleaning or replacement.
1.3.4 RS 232 C interface
The interface will operate either in connection with a prin-
ter, remote control terminal or a computer.
The RS 232 C interface is suitable for transmitting data
over distances up to 20 m. By using converters such as
for example RS 422 or fibre optical links, much greater
distances can be covered. Moreover, with the aid of a
modem (modulator for transmission in the audio range
and demodulator for converting the signals back to digi-
tal) data may be transmitted down phone lines.
