Televac MV2A Vacuum Controller - Vacuum Pressure Controller

Part Number: 2-7900-071

The Televac MV2A vacuum controller (also called a vacuum control unit or vacuum pressure controller) can be connected to 1 Televac passive vacuum gauges (the 2A thermocouple). It includes a 0 to 5 V DC analog output for the gauge connected to the vacuum controller for simple integration with a PC or PLC, and 2 set point relays to act as a vacuum pressure controller for process control in your vacuum system.

The MV2A vacuum controller’s user interface includes a bright LED display of the current vacuum measurement and indication LEDs for the setpoints, which can be set via two buttons on the front panel. This vacuum control unit supports nitrogen/air, and Televac can provide compensation factors for argon, hydrogen, helium, neon, krypton, and carbon dioxide. The MV2A is our simplest vacuum controller, providing an efficient, low-cost solution for various vacuum markets and applications.

CC-10 Active Vacuum Gauge – This gauge utilizes dual-sensor technology to replace multiple conventional vacuum gauges, permitting seamless measurement of twelve decades of pressure. It has a variety of features including a wide range of measurement from 1 × 10-9 Torr up to 1000 Torr, RS-485 communications, three programmable set points, and a selectable analog output and a bright LED display. Options can be set from either four touch controls located on the front of the unit or through RS-485 communications. The simplicity of use and wide measurement range make this unit an excellent choice for a variety of vacuum applications.

MM200 Vacuum Sensor Controller – The MM200 controls any Televac vacuum sensor including cold cathode, convection, diaphragm, hot ion, and thermocouple sensors. It also has optional features including up to 8 relay set points and RS-232/RS-485 communications. The large, bright LED display makes it easy to read from a distance. The MM200 is a modular unit, allowing customers to choose a vacuum sensing solution specific to their needs.
