Supply Voltage Mounting Orientation Calibration Medium Overpressure Analog Output Resolution Operating Temperature Storage Temperature Bakeout Temperature Response Time Accuracy 1 x 10-9 to 1 x 10-2 Torr Controller-dependent Any Dry air or nitrogen 150 PSI Controller-dependent 0° to +50° C -20° to +70° C 400° C (without magnets) 150° C (with magnets) < 10 ms 7F Double Inverted Magnetron Cold Cathode Sensor Part Number: 2-2144-052Operating Specifications1 Operating Range 1 x 10" to 1 x 10" Torr Analog Output Controller-dependent The 7F cold cathode sensor has a measurement range from 1 x 10-11 up to 1 x 10-2 Torr. It indirectly measures absolute pressure by ionizing gas in the presence of a magnetic field. Unlike hot filament sensors, the 7F is resistant to inrushes of gas. The design of this sensor allows for an extended range of measurement and high bakeout temperatures up to 400° C. The 7F can be operated by several Televac controllers, including the MM200 or MC300 rack mountable controllers and the MP7FR. The MM200 and MC300 controllers automatically operate the cold cathode to provide a full range vacuum measurement solution when the 7F is used in conjunction with rough vacuum sensors. Dimensions See dimensional drawings Stainless Steel Ceramic • Competitively priced • Compact design • Minimal stray magnetic field • Resistant to inrushes of gas • High bakeout temperature • Interchangeable with 7E, 7FC, 7FCS • Excellent customer support • Designed and manufactured in the United States of America • RoHS compliant 1 See the Televac website at www.televac.com for a list of definitions for terms used in the operating specifications. All test data was acquired at 23° C.
