7B Penning Magnetron Cold Cathode Sensor Part Number: 2-2100-2XXOperating Specifications1 Operating Range 1 x 10-7 to 1 x 10-3 Torr Analog Output Controller-dependent Supply Voltage Controller-dependent Calibration Medium Dry air or nitrogen Analog Output Resolution Controller-dependent Accuracy 1 x 10-6 to 1.0 x 10-3 Torr ± .2 decade The 7B Penning magnetron cold cathode sensor has a measurement range from 1 x 10-7 up to 1 x 10-3 Torr. It indirectly measures absolute pressure by ionizing gas in the presence of a magnetic field. Unlike hot filament sensors, the 7B is resistant to inrushes of gas. The design of this sensor allows for easy disassembly enabling quick cleaning and extended use. The 7B can be operated by the Televac MM200 or MC300 rack mountable controllers. These controllers automatically operate the cold cathode to provide a full range vacuum measurement solution when the 7B is used in conjunction with rough vacuum sensors.
