Gemini™ MxG5xx ATM to Ultra-High Vacuum Gauge

The INFICON Gemini™ Inverted Magnetron Vacuum Gauge is the workhorse for all vacuum measurement applications. While Gemini MPG50x combines two sensor systems in one small device to measure from atmosphere down to 1x10– 9 mbar, the Gemini MAG50x is a pure cold cathode sensor System (without Pirani element) which covers the range from 1x10-2 mbar to 1x10– 9 mbar. The patented ultra-low magnetic stray field design opens up a whole new range of applications. A unique interchangeable dual chamber sensor unit avoids cleaning cycles and reduces maintenance, making Gemini the most robust and economical vacuum gauge of its kind.

Gemini Cold Cathode and combination comes with fully integrated digital electronics, providing ultimate flexibility for system integration. The Cold cathode and Pirani combination version (MPG) option provides seamless transition, reliability, practicality and flexibility across wide ranging applications.

MAG and MPG Gemini are now available with EtherCAT fieldbus and setpoints as MAG55x and MPG55x.

For corrosive applications we suggest to use the ceramic coated version MxG5x4. Feedthrough and Pirani inside the sensor head are fully ceramic coated for enhanced corrosion resistance.

Gemini™ Cold Cathode and combination sensor`s come with fully integrated digital electronics, providing ultimate flexibility for System Integration.

Both, cold cathode and Pirani combination sensor Option provide seamless Transition, reliability, proactivity and flexibility across wide ranging applications.

Advantages
