Pfeiffer Vacuum

5.3.3 ModulLine

The ModulLine series includes three passive Pirani vacuum sensors TPR for the pressure range of 1,000 to 8 · 10-4 hPa and three cold cathode vacuum sensors IKR for the pressure range of 5 · 10-3 to 10-11 hPa. Because these vacuum sensors do not contain any electronics, they are suitable for use in high-radiation environments. A large range of cables is available to enable the control unit to be installed at a great distance from place of use of the vacuum sensors.

A TPG 300 with the following features serves as the control unit:

  • Modular design for a variety of measuring boards
  • Two measuring boards can be inserted, as well as an RS-232/RS-485 interface board with relay outputs
  • Connection of up to four vacuum sensors
  • Fieldbus connection is possible
