VSA200 abs. switch
INFICON Vacuum Switches are designed for accurate and reliable pressure detection. These robust electronic switches are used in all vacuum applications, including pressure interlock. The switches are available in two versions, absolute (references vacuum) or differential (references ambient).
Benefits
- Corrosion resistant all stainless steel design
- Robust design, cleanroom compliant
- Easy installation with setpoints factory preset or field-adjustable
Features
- IP 44 protection
- Relay output with potential free contacts
- High-accuracy temperature compensated sensor
- Pressure range 1×10-9 mbar … 2 bar
Typical Applications
- Atmospheric pressure detection for all vacuum applications
- Pressure interlock (power supplies, gas supplies, pumps, valves, actuators, etc.)
- Vacuum to high vacuum
