(10 - 26,000 Torr)

photo - 52A Baratron Flow-through, Absolute Pressure/Vacuum Switch (10-26,000 Torr)

The MKS Instruments 52B Flow-through Pressure Switch offers accurate and reliable protection vacuum/pressure processes. Designed for applications where a DC signal output is not required, these switches provide relay outputs that are readily interfaced with alarms, valve actuators, computers, process controllers, load locks and other protection devices. The 52B is referenced to vacuum.

Features & Benefits:

  • High reliability reduces downtime
  • Superb set point accuracy and repeatability
  • All-metal, all-welded construction exposes only stainless steel and Inconel® for corrosion resistance
  • Switch relay can be set to energize above or below set point for fail-safe operation
  • Low hysteresis improves set point accuracy

Applications:

The 52B Baratron® Absolute Pressure Switch provides precise control for a wide variety of production applications including semiconductor processing tools, high vacuum pumps, compressors, blowers, medical equipment and machine tools. The 52B is often used in conjuncton with soft pumping, gas box switching, and safety interlocks.
