Total pressure measurement in areas with ionizing radiation


Extremely rugged gauge heads for operation in areas with high radiation levels, as well. They are especially suitable for UHV applications.

Controllers and accessories

Controllers TPG 300 are modular and can be configured variously. Two measuring card slots for the operation of up to 4 gauges. An interface slot for various relay and interface cards. For pressure range 1 · 10-11 to 1000 hPa. Controller IMG 400 for the operation of hot cathode gauges with additional connections for Pirani and capacitive gauges from the ActiveLine family. An interface slot for a Profibus interface card (optional). For pressure range 2 · 10-12 to 1100 hPa.
Measuring cables for connection of the ModulLine gauges with the respective controller TPG 300 or IMG 400. The cables are available in standard version for temperatures up to max. 80 °C and as high-temperature cables for temperatures up to 200 °C or up to 250 °C.

Total pressure measurement in areas with ionizing radiation

The ModulLine series includes three Pirani TPR vacuum gauges with a measuring range of 1,000 to 8 · 10-4 hPa, three IKR cold cathode vacuum gauges with a measuring range of 5 · 10-3 to 1 · 10-11 hPa, and two IMR hot cathode vacuum gauges with a measuring range of 1 · 10-2 to 2 · 10-12 hPa. Since these vacuum gauges do not contain any electronics, they are also suitable for use in high-radiation environments. An extensive range of cables, including high-temperature cables and cables with double shielding, and two controllers, complete this measurement equipment line.

The individually configurable TPG 300 controller can have two measuring boards for up to four TPR and IKR-type vacuum gauges. Another socket is for an interface board for serial interfaces RS-232/RS-485 and relay contacts. Controller IMG 400 is used for connecting IMR-type vacuum gauges. Both controllers can also be connected to Profibus DP with an optional interface board.
