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.
액티브 게이지 대 진공 컨트롤러 - 왜 다른 게이지를 선택합니까?
진공 컨트롤러 솔루션과 액티브 게이지 솔루션간의 주요 차이점은 제어 전자 장치(및 디스플레이)의 위치 지정과 여러 패시브 게이지에서 판독값을 동시에 연결하고 표시하는 진공 컨트롤러의 기능입니다.
진공 컨트롤러를 사용하면 수동 게이지가 케이블로 진공 컨트롤러에 연결되므로 제어 전자 장치 및 진공 센서를 10피트에서 300피트로 분리할 수 있습니다. 이는 방사선이 존재하는 환경(전자 장치가 방사선에 의해 신속하고 손상됨) 또는 원격으로 또는 진공 센서와 다른 위치에 측정을 표시해야 하는 응용 분야에 특히 유용합니다.
액티브 게이지는 일부 응용 분야(예: 제어 캐비닛에 공간이 제한된 진공 용광로)에 공간을 절약할 수 있는 기회를 제공합니다. 액티브 게이지는 또한 교정과 관련하여 진공 컨트롤러가 부족할 수 있는 유연성을 제공합니다.
- ISO 17025 accredited and NIST traceable calibrations without returning your cables (meaning cables don’t need to be removed from your system)
- 별도의 저진공 게이지와 높은 진공 게이지를 사용하면 다양한 교정 간격으로 게이지를 반환할 수 있습니다.
- 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
- 교정을 위해 반환할 진공 컨트롤러 상자 없음
- 교정을 위한 가동 중지 시간 및 유지 보수를 줄이면서 상당한 비용 절감
MX2A 써모커플
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.
MX4A 대류
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 콜드 캐터드
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 콜드 캐터드
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 와이드 레인지
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.
