Televac® Launches New MX7M Cold Cathode Active Gauge

Huntingdon Valley, PA, December 01, 2020; Televac® – The Fredericks Company, an industry-leading innovator and manufacturer of vacuum measurement and tilt measurement products, today announced the launch of the Televac® MX7M Cold Cathode Active Vacuum Gauge.

The MX7M Cold Cathode Active Gauge features the new Televac® 7M triple inverted magnetron cold cathode ionization gauge, which has a wide operating range and is the only cleanable cold cathode active gauge 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. The MX7M Cold Cathode Active Gauge is designed for e-beam welding, thin film, R&D, and analytical equipment for surface sciences, as well as other existing active vacuum gauge and cold cathode gauge users.

Compared to our other cold cathode gauges, this vacuum gauge is a compact and low-cost design with all-metal seals that significantly reduce outgassing. It can be easily disassembled for cleaning and gauge replacement to save users time and money. It also features a multi-color OLED display, a configurable 0 to 10 V DC analog output for vacuum measurements, digital RS-485 communications, and set points for process control. All features of this cold cathode gauge are accessible through the display and touch controls or through the digital communications.

The MX7M Cold Cathode Active Gauge can also be connected to an EthernetIP network via the Televac® MX Active Gauge EthernetIP Gateway, the first and only solution designed to provide EthernetIP communication between Televac® active vacuum gauges and Rockwell Automation® Allen-Bradley® PLCs.

“Televac® is always designing new, cutting-edge products to maximize productivity and efficiency for our users,” said Heidi McKenna, President of Televac®-The Fredericks Company. “This cold cathode gauge combined with the Televac® MX2A or MX4A provides full range vacuum measurement and makes it the optimal solution for many industries.”

The Televac® brand provides a complete line of cold cathode, thermocouple, convection, and hot ionization gauges for a wide range of applications and the most demanding environments. Dedicated solely to vacuum gauging and calibration services, Televac® provides solutions for heat treating, national laboratories, cryogenics, vacuum distillation, and industrial gas applications, among many others, with fast lead times of 2 weeks or less and industry-leading performance. Covering the entire practical vacuum measurement range from atmosphere to UHV, Televac® instruments deliver rapid response vacuum measurements with superior longevity, contamination resistance, and accuracy.
