Description

BARATRON TYPE 141 VACUUM SWITCH

 

The 141A Absolute Pressure Switch offers fast, accurate, and reliable protection for vacuum equipment and processes. Designed for applications where a DC signal output is not required, the 141A has relay outputs that are easily interfaced with alarms, valve actuators, computers, process controllers, and other protection devices.

 

  • Fully adjustable set point for flexibility
  • All-metal, all-welded Inconel® and stainless steel construction for corrosion resistance
  • Fast response switching – 20 msec
