TELEVAC MP7FR Double Inverted Magnetron Cold Cathode

2-7950-X-YY and 2-7970-X-YY

The TELEVAC MP7FR Active Gauge utilizes an easily replaceable TELEVAC 7F double inverted magnetron cold cathode vacuum sensor. It has a variety of features including a wide range of measurement from 1×10-11 Torr to 1×10-2 Torr, a programmable set point, a factory settable analog output, and an LED display. This unit indirectly measures absolute pressure by ionizing gas in the presence of a magnetic field. Unlike hot ion sensors, this unit is resistant to inrushes of gas. The design allows for easy disassembly for replacement of the sensor.
