MAG050, MAG060, MAG070
Cold Cathode Gauges - Passive
The gauge heads MAG050, MAG060 and MAG070 are
long-established passive, inverted magnetron cold
cathode gauges intended to operate with the Vacuum
Gauge Controllers VGC094 and VGC083C. They aredesigned for vacuum measurement in the pressure
range from 1×10-11 (MAG070) to 5×10-3 mbar. The
compact metal design provides a robust solution
suitable for general vacuum applications.
MAG050 is a simpler cold cathode gauge with anelastomer sealed feedthrough. Thanks to their allmetal design, MAG060 and MAG070 respond to needsof demanding applications requiring bake-out
temperature up to 250 °C or high ionizing radiation
resistance. Both allow pressure measurement in theUHV range. The triaxal connection of MAG070 allows
lowest pressure reading (down to 1×10-11 mbar) andlong distance operation between the gauge head andcontroller (up to 500 m). All gauge heads have anignition aid mounted on the anode (reducing the cold
cathode ignition time at low pressure) and can be easily
disassembled and cleaned, allowing long term use withminimal downtime.
ADVANTAGES• Reliable and proven gauge head design, based on the inverted magnetron principle• Large vacuum pressure measurement range capability from 1×10-11 (MAG070) to 5×10-3 mbar
• Bakeable to 150 °C (MAG050) or 250 °C (MAG060, MAG070)• Good ignition properties• Corrosion resistant with ceramic feedthrough• Radiation resistant design available (MAG060, MAG070)• Easy to maintain, low cost of ownership
APPLICATIONS• General vacuum measurement and control for demanding and/or high temperature applications from low tothe high vacuum range
OPERATING UNITS• Vacuum Gauge Controller VGC094 and VGC083C (MAG070 excluded)1
