Televac MP7ER Cold Cathode

2-7950-XYY and 2-7970-XYY

The Televac MP7ER Active Gauge utilizes an easily replaceable Televac 7E double inverted magnetron cold cathode vacuum sensor. It has a variety of features including a wide range of measurement from 1*10-8 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 enabling quick cleaning of the sensor and extended use.
