MKS offers several different models of vacuum/pressure switches for accurate and reliable protection of vacuum equipment, atmospheric switching, and 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.
141A and 142A Baratron® Vacuum Switches operate on an input voltage of ±15VDC, and offer absolute calibrations from 1 to 1000 Torr (1.33 to 1333 mbar). Their trip points can be customer-adjusted from 0.2 to 100% of the full-scale range. The 141A Baratron® Vacuum Switch operates at ambient temperature, while the 142A operates at 100°C for use in difficult applications where process contamination is likely.
(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.
