With increased emphasis on accountability,
the MG3 Digital Process Sentry offers the
tools required for process development,
production monitoring, data collection, and
analysis to support your ISO, GMP and TQM
requirements.
The MG3 represents the very latest
technology in resistance weld monitoring;
it provides precision real-time dynamic
measurement of all the welding variables
and is an invaluable tool for:
Process Development
Welding Evaluation and Research, DoE
Studies, Process Optimization, Process
Validation
Process Monitoring
Data Logging, Setting Process Limits, Electrode
Maintenance,Troubleshooting, Set-up
Verification, Statistical Process Control
Quality Control
Traceability, Process Certification and
Analysis, Calibration Confirmation, Statistical
Process Control
With three models to choose from, the
MG3 can monitor up to two simultaneous
channels of current and voltage from up to
two AC, DC or CD
power supplies for spot
or seam welding. In addition to the basic
model, the W1 and W2 models have single
and dual channel displacement capability,
respectively, and also offer inputs for force
and pressure sensors.
Upper and lower limits can be set to trigger
alarms for all measurements; for more
advanced users, these limits can be set as
envelopes that follow the contour of the
waveform. Judgment of good/bad welds
can be determined by status LED’s on the
front panel and outputs from the MG3’s I/O.
All welding parameters are stored in internal
memory, available from the built-in RS-232
port, and data may be transferred to a
Compact Flash (CF) card and directly
exported into Excel® for user-defined
analysis. The MG3 also has a convenient
“SNAPSHOT” feature to save screenshots
for reports. Comprehensive SPC functions
include run chart logging and histograms.
