Description

ARATRON TYPE 141 VACUUM SWITCH

 

MKS BARATRON TYPE 141 VACUUM SWITCH offers fast, accurate, and reliable protection for vacuum equipment and processes. MKS BARATRON TYPE 141 VACUUM SWITCH 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.

The 141 and 142 Vacuum/Pressure switches offer fast, accurate, and reliable protection for vacuum equipment and processes. Designed for applications where a Dc signal output is not required. The 141 and 142 provide relay outputs that are readily interfaced with alarms, valve actuators, computers, process controllers, or 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
