The Fredericks Company’s Televac® vacuum measurement brand designs and manufactures single channel and multi-channel vacuum controllers (also called a vacuum control unit or vacuum pressure controller) for use with our passive gauges, including thermocouple gauges, convection gauges, and diaphragm gauges for low vacuum measurement, and cold cathode gauges and hot ion gauges for high vacuum measurement.
Each vacuum controller has many features to simplify integration, including analog 0 to 10 V DC outputs for each connected gauge, digital RS-232, RS-485, EthernetIP, and USB communications, and set point relays for process control. Our multi-channel vacuum controllers are highly configurable, connecting to up to 10 passive gauges to give a measurement range of 10-11 Torr to 10,000 Torr.
In addition to our rack and panel mountable solutions, Televac® also offers portable vacuum controllers and active vacuum gauges. While our rack/panel mountable controllers use a 110/220 V AC power supply and connect to passive vacuum gauges with cables, our portable units are battery powered (and connect to passive gauges with cables), and our active vacuum gauges have an electronics head that plugs directly into a passive vacuum gauge (and uses a 24 V DC supply voltage).
If you’re interested in a portable controller, we’d suggest checking out the VacuGuard™. If you’re interested in an active vacuum gauge, we’d suggest checking out the MX4A for low/rough vacuum measurement and the MX7B for high vacuum measurement.

Vacuum Controller and Vacuum Control Unit Solutions
The MX200 is our most versatile multi-channel vacuum controller, connecting to up to 10 passive vacuum gauges to provide vacuum measurement from 10-11 Torr to 10,000 Torr. It has 0 to 10 V DC analog outputs for each connected vacuum gauge, and up to 8 optional set point relays for process control. The serial version of the MX200 includes RS-232, RS-485, and USB digital communications, and the EthernetIP version of the MX200 includes EthernetIP and USB digital communications for connecting directly to Rockwell Automation® Allen-Bradley® PLCs.
The MC300 is essentially a smaller, less configurable version of the MX200 (and depending on your MX200 configuration, the MC300 can also be lower cost). This unit controls up to 3 passive vacuum gauges to provide vacuum measurement from 10-11 Torr to 1000 Torr. It has 0 to 10 V DC analog outputs for each connected vacuum gauge along with 4 set point relays for process control. This unit does not include any digital communications (RS-232, USB, etc.).
The MV2A is a single-channel controller that connects to our 2A thermocouple gauge, giving it a measurement range of 1*10-3 Torr (1 micron) to 20 Torr (20,000 microns). It has a digital display to show vacuum measurements along with a 0 to 5 V DC output corresponding to its current vacuum reading. The MV2A also has 2 set point relays for process control.
The Compact 2A is another single-channel controller, similar to the MV2A, except that the Compact 2A has an analog display to show vacuum measurements. The Compact 2A connects to our 2A thermocouple gauge, giving it a measurement range of 1*10-3 (1 micron) to 20 Torr (20,000 microns).
