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.

Some of the most common markets where a vacuum controller is used are heat treat and vacuum furnaces and national labs and research and development.

The Fredericks Company’s Televac® vacuum pressure measurement brand designs and manufactures portable vacuum controllers (also sometimes called a vacuum control unit or vacuum pressure controller, see our handy terminology reference) for use with our 2A thermocouple gauges and DV4 and DV6 thermocouple gauges. We offer two types of portable vacuum pressure controllers; digital vacuum controllers (which have a digital display) and analog vacuum controllers (which have an analog display).

What’s a portable vacuum controller? A portable vacuum control unit is a scaled down (lighter and smaller), battery powered version of our standard vacuum controllers that come with a carrying case and coiled cables to save space. These vacuum controllers only read from one thermocouple gauge at a time, giving them a range of 1 micron (0.001 Torr) to 20 Torr. They’re most commonly used for low vacuum applications like cryogenic and industrial gas storage and the HVAC market.

What are some of the benefits of the 2A thermocouple gauge? The 2A thermocouple gauge has been used in the cryogenic and industrial gas storage industry for decades, testifying to the gauge’s reliability and ruggedness. The filament design and operating temperatures of the 2A thermocouple gauges make it the most contamination resistant passive gauge offered by Televac®.

NIST traceable calibration is also available for all of our portable vacuum controllers. Click here to learn more!

Televac Active Digital Vacuum Gauges

The Fredericks Company’s Televac® vacuum pressure measurement brand designs and manufactures active gauges (also called analog or digital gauges) that combine Televac®’s passive gauges (also called vacuum sensors) and controlling electronics into one compact unit for pressure measurement.

Our active gauges cover the entire practical vacuum range from 10-11 Torr to 1000 Torr and feature bright OLED displays and easy to use touch controls, in addition to RS-485 communications, allowing the user to adjust settings such as measurement units, set points, and calibration directly through the unit’s display or remotely through digital communications.

These active gauges are compact, easy to use, and cost effective solutions for a wide range of vacuum measurement applications, the most common being heat treat and vacuum furnaces, vacuum distillation, thin film deposition, and semiconductor manufacturing equipment.

Looking for full-range vacuum measurement and not sure where to start? Check out our MX4A active convection gauge and our MX7B active cold cathode gauge (also sometimes called a CC gauge), when used together these units provide a measurement range of 10-8 Torr to 1000 Torr.

ETI 핫 이온

Our ETI brand offers various types of vacuum technology including glass and nude hot ion gauges (also called a hot filament, Bayard-Alpert, BA, or BAG gauges or vacuum sensors) for high-vacuum measurement from 10-10 Torr to 10-3 Torr using tungsten filaments. This vacuum technology is popular in the semiconductor industry for the higher accuracy it offers over cold cathode vacuum technology. While hot ion gauges provide better accuracy than cold cathode gauges, hot ion gauges are also more expensive, cannot be cleaned, and are more susceptible to contamination so they don’t last as long.

Televac® cables are used to connect passive gauges to controllers, or to connect active gauges to your vacuum system. Many standard cable lengths are available, with cables as long as 300 ft (91 m) for larger vacuum systems. Our robust gauge cables are designed to be plugged and un-plugged extensively over their lifetime, with built-in strain relief and durable connectors to prevent damage or breakage over years of use.


Televac® accessories include a variety of spare parts for our vacuum technology along with vacuum sensor filters and vacuum sensor simulators. Filter vacuum technology helps prevent contamination of your gauges, extending their life, reducing the need for cleaning, and keeping the gauge accuracy in tolerance for longer, all meaning that you spend less money on gauge maintenance. Vacuum sensor simulators can be used to diagnose many different issues with vacuum controller and active gauge electronics, providing an electrical signal which is equivalent to a typical passive gauge at various pressures.

교정 및 서비스

We offer vacuum calibration services for all of our vacuum technology, and our vacuum calibration services include both standard vacuum calibration or NIST traceable vacuum calibration for any of our active gauges or controllers with passive gauges. Our vacuum calibration services typically have much shorter lead times than our competitors with turn-around times of 1 to 2 weeks once we receive your equipment, with expedited services also available. Also, if you’re having a problem with any of your vacuum equipment, you can send it back to us for evaluation and repair if necessary.
