Download Datasheet

Not recommended for new designs.
Replaced by Televac® MX7B and MX7M Active Gauge.

Part Numbers: 2-7970-152, 2-7970-352

Features and Benefits:

  • Compact design
  • Mountable in any orientation
  • Minimal stray magnetic field
  • Superior unit-to-unit performance
  • Excellent customer support

The Televac® MP7FR Active UHV 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.
