Televac® Active Digital Vacuum Pressure Gauges
Televac® Active Digital Vacuum Gauges
The Fredericks Company’s Televac® vacuum pressure measurement brand designs and manufactures active vacuum pressure gauges that combine Televac®’s passive vacuum pressure gauges 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, when used together these units provide a measurement range of 10-8 Torr to 1000 Torr. Click here to learn more!
What’s an active vacuum pressure gauge?
Terminology varies from different manufacturers, but at Televac® we differentiate between passive gauges and active gauges (check out our terminology reference).
A passive vacuum pressure gauge, such as our 2A thermocouple gauge or our 7B cold cathode gauge, needs controlling electronics to convert the electrical signal from the gauge into a vacuum measurement. This conversion can be done by a vacuum controller, which can control multiple gauges at a time, or by an active gauge, where the control electronics are integrated into an assembly which is directly attached to the passive gauge.
Active gauges are also sometimes called digital vacuum gauges or analog vacuum gauges, because they have a digital display and digital communications, along with an analog 0 to 10 V DC output.
Medidores activos vs. controladores de vacío. ¿Por qué elegiría uno sobre el otro?
Las principales diferencias entre una solución de controlador de vacío y una solución de calibrador activo son el posicionamiento de la electrónica de control (y la pantalla), y la capacidad de un controlador de vacío para conectar y mostrar las lecturas de múltiples calibradores pasivos simultáneamente.
Con un controlador de vacío, los medidores pasivos están conectados por cables al controlador de vacío, permitiendo la separación de la electrónica de control y los sensores de vacío en cualquier lugar de 10 a 300 pies. Esto es particularmente útil para los entornos en los que hay radiación (los componentes electrónicos se dañan rápidamente por la radiación), o en aplicaciones en las que las mediciones deben mostrarse a distancia o en un lugar distinto al de los sensores de vacío.
Los medidores activos ofrecen la oportunidad de ahorrar espacio para algunas aplicaciones (como un horno de vacío con espacio limitado en el armario de control). Los medidores activos también ofrecen la flexibilidad que a veces carecen los controladores de vacío cuando se trata de la calibración:
- ISO 17025 accredited and NIST traceable calibrations without returning your cables (meaning cables don’t need to be removed from your system)
- Los medidores de bajo y alto vacío separados permiten devolver los medidores a diferentes intervalos de calibración.
- This is particularly of interest for end users adhering to NADCAP and AMS standards, where high vacuum gauges (like the MX7B active cold cathode gauge) must be calibrated every 3 months, and rough vac gauges (like the MX4A active convection gauge) must be calibrated annually
- No hay caja controladora de vacío que devolver para su calibración
- Ahorro significativo de costos con menos tiempo de inactividad y mantenimiento para la calibración
Termopar MX2A
The MX2A active thermocouple features the Televac® passive 2A thermocouple gauge (sometimes called a Pirani gauge), one of our most robust and contamination resistant low vac gauges due to its filament design and operating temperature. This compact unit measures from 10-4 Torr to 1000 Torr and comes standard with a color OLED display, touch controls, RS-485 communications, and an analog 0 to 10 V DC output corresponding to its vacuum measurements. Sensor replacement is fast and simple with no screws to remove.
Convección MX4A
The MX4A active convection utilizes the Televac® passive 4A convection gauge (also sometimes called a Pirani gauge) and measures from 10-4 Torr to 1000 Torr, offering ±10% accuracy over its operating range. This low cost, compact unit features a color OLED display, touch controls, RS-485 communications, programmable set points, and an analog 0 to 10 V DC output (also making it an analog vacuum gauge) corresponding to its measurements. Sensor replacement is fast and simple with no screws to remove.
MX7B Cátodo frío
The MX7B active cold cathode features the Televac® passive 7B Cold Cathode gauge and measures from 10-8 Torr to 10-3 Torr, and provides full range vacuum measurement when combined with the MX4A active convection gauge. Our patented Penning cold cathode technology offers superior contamination resistance compared to similar competing technology. Like our other MX Series active gauges, the MX7B is equipped with an easy to read OLED display, touch controls, RS-485 and USB communications, and an analog 0 to 10 V DC output. The 7B sensor is fast and simple to remove (only one screw) for cleaning or replacement to extend the gauge’s life.
MX7M Cátodo frío
The MX7M active cold cathode features the Televac® 7M cold cathode ionization gauge, which has a wide operating range of 5*10-11 to 1*10-2 Torr. This is the only cleanable cold cathode on the market which measures into the 10-11 Torr range. The new triple inverted magnetron design improves the overall accuracy of the vacuum gauge by improving linearity while significantly decreasing the stray magnetic field.
CC-10 Wide Range
The CC-10 active wide range is a wide range active gauge that utilizes dual sensor technology to deliver seamless measurement from 10-9 Torr to 990 Torr. A crystal sensor measures from atmosphere to 10-3 Torr and our patented double inverted magnetron cold cathode gauge is used to measure from 10-2 to 10-9 Torr. The CC-10 features an easy to use front panel with an LED display so options can be set using the touch controls or through RS-485 communications. It also has built-in set points and features an analog 0 to 10 V DC output (also making it an analog gauge) corresponding to its vacuum reading.
MX Active Gauge EthernetIP Gateway
Looking for a digital gauge with Ethernet/IP communications? The new MX Active Gauge EthernetIP Gateway provides EthernetIP communications and power connections for up to 4 Televac® MX series active gauges and 1 capacitance diaphragm gauge (CDG). All MX series active gauge features are accessible via EthernetIP, allowing you to integrate things like calibration and changing gas types into your PLC and HMI.
