141A Baratron® Absolute Ambient Vacuum Switch
(0.1-1000 Torr)

The MKS Instruments 141A Absolute Ambient Pressure/Vacuum 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.

Features & Benefits:

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

Applications:

Designed for applications where a DC signal output is not required, the 141A is ideal for protection of expensive equipment or processes such as: high vacuum pumps, mass spectrometers, lasers, plasma systems.
