The following combination sensors are available:<br />
PCR 260 capacitive diaphragm-Pirani combination transmitter with a measurement<br />
range from 1,500 to 5 . 10 -4 mbar<br />
PKR 251 and 261 Pirani-cold cathode combination transmitters with measurement<br />
ranges from 1,000 to 5 . 10 -9 mbar<br />
PBR 260 Pirani/Bayard-Alpert combination transmitter with a measurement range<br />
from 1,000 to 5 . 10 -10 mbar.<br />
ActiveLine transmitters offer the following advantages:<br />
There are three control units for one, two or six transmitters<br />
Any transmitter can be operated with any control unit<br />
Uniform connection cable<br />
3.3.1.3 ModulLine<br />
The ModulLine series includes three TPR Pirani vacuum gauges with a measurement range<br />
from 1,000 to 8 . 10 - 4 mbar and three IKR cold cathode measuring tubes with measurement<br />
ranges from 5 . 10 - 3 to 10 -11 mbar. Because these vacuum gauges do not contain any electronics,<br />
they are suitable for use in high-radiation environments.<br />
TPG 300 Control Unit Up to three boards<br />
Figure 3.11: TPG 300 control unit for ModulLine vacuum gauges<br />
A TPG 300 with the following features serves as the control unit:<br />
Two measurement boards can be inserted, as well as<br />
An RS-232/RS-485 interface board with relay outputs<br />
Connection of up to four vacuum gauges<br />
Fieldbus connection is possible<br />
