Technology Leadership

MKS was the first company to offer an RGA compatible

with modern Ethernet based web-enabled wide area

network installations. The e-Vision 2 continues this

development for the highest flexibility and connectivity

through the use of industry standard communication

hardware and software. The e-Vision 2 optimizes the roles

required of a complex sensor by having two dedicated

processors, one optimized, proprietary processor for data

acquisition and one industry standard CE operating system

processor for external communications through field proven

TCP-IP technology.

The advantages of this design approach are fast, accurate

data from a robust RGA sensor using industry standard,

flexible communication protocols, all at the best possible

value for your investment.

Hardware Performance

Sensors

Field proven MKS quadrupole mass analyzers, with twin

filaments as standard, ensure minimum downtime during

critical diagnostic testing.

The RGA is available with an optional dual detector

including a faraday detector and microchannel plate

electron multiplier for detection to e-14 mbar.

Electronics

Data acquisition occurs through all solid state, wide

dynamic range, fast settling detector electronics. This

technology prevents large peaks from causing false

positive measurements on small peaks.

Temperature stabilized critical components mean that

signal stability and baseline drift are improved, allowing the

unit to be used without frequent recalibration if the vacuum

chamber is stable but ambient air temperature fluctuates.

Software Flexibility

Built-in Web Application

A web interface using industry standard technology allows

control of the e-Vision 2 as well as calibration, operation

and data export through a non platform-specific web

browser from anywhere on a network.

Using the ASCII protocol and TCP-IP communication, any

third party software can send and receive commands and

data from the e-Vision 2.

In addition to the standard, built-in web applications,

software control is also available through an optional

Windows application, offering the best possible fit to any

customer requirement.

• Store RGA data and recall it back into the Recall viewer

• Annotate graphs with notes

• Run several RGAs from one software package
