New series of transducer type "G-RTAN series Multi Ionization Gauge" that is capable of connection to differet type sensor heads.
This product, which is a triode type ionization gauge, is capable of longer life stable measurement in harsh environment for vacuum gauges because of low deterioration of sensitivity.
Improved to be more user-friendly taking over the concept of long-life and low running cost.

Features
- High usability: Set point setting, condition check, etc. by connecting PC/Android.
- Filament life notification function: An advance warning can be made before the life of ionization vacuum gauge by watching flilament power.
- ULVAC own concept: Capable of connection of different measurement range sensor heads according to application.
- Compact: Significantly miniaturized compared to the previous series (56% reduction of controller volume). World’s smallest class.
- Larger selection: EtherCAT spec to be available in addition to analog output spec and serial communication spec.
- World's first metal type triode ionization gauge: Long life even if in harsh environment and no worry of such damage as glass type.
- Wide range measuremnt: Measurment from atmospheric pressure to ultra figh vacuum (1 x 10+5 to 1 x 10-5Pa) is possible (when using with an optional unit SWU10-R).
- Precise atmospheric pressure sensing: Atmospheric pressure check for chamber open is available (when using with an optional unit SAU).
Applications
- Ultimate pressure check or process control for vacuum equipment for OLED touch panels.
- Ultimate pressure check for industial vacuum equipment such as vacuum furnaces.
- Measurement in hydrocarbon rich atmosphere.
- In case that replacement cycle of sesnosr head is required.
*Please contact in case of using corrosive gases (halogen gases).
