Page 4: Introduction
The MC300 is a rack-mountable vacuum controller, which operates up to three vacuum sensors, including cold cathode, mini Bayard-Alpert, thermocouple convection, and thermocouple sensors. The capability of controlling a wide range of sensors allows the MC300 to provide a maximum vacuum measurement range of 1 Torr to 1,000 Torr. -

Page 21: Configurations
3 CONFIGURATIONS 3 Configurations The MC300 can be configured to run two low vacuum sensors and an optional high vacuum sensor. The low vacuum sensors available are the 2A Thermocouple sensor and the 4A Thermocouple Convection sensor. The two low vacuum sensors must be the same type. The optional high vacuum sensors are the 7B Penning Magnetron cold cathode, 7E/F/FC Double Inverted Magnetron cold cathode, and the Mini Bayard-Alpart sensor. -

3.1 Sensor Descriptions 3 CONFIGURATIONS 3.1.3 7B Penning Magnetron Cold Cathode The 7B Penning Magnetron cold cathode sensor has a measurement range from 1 10 up to 1 10 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 in-rushes of gas. -

High vacuum versions of the MC300 include automatic operation of the high vacuum sensors based on the low vacuum sensor in Channel 1. Channel 2 is also a low vacuum sensor. The high vacuum sensor is labeled "ION GAUGE" on the MC300 display and is referred to as Channel 3. 4.1 Cold Cathodes Configurations For MC300 configurations that contain a cold cathode (either 7B or 7E/7F/7FC), the cold cathode... -
